U.S. Route 12 in Michigan

March 06, 2023

This article is about the section of highway in Michigan. For the entire length of highway, see U.S. Route 12.

US Highway 12 (US 12) is an east–west US Highway that runs from Aberdeen, Washington, to Detroit, Michigan. In Michigan it runs for 210 miles (338 km) between New Buffalo and Detroit as a state trunkline highway and Pure Michigan Byway. On its western end, the highway is mostly a two-lane road that runs through the southern tier of counties roughly parallel to the Indiana state line. It forms part of the Niles Bypass, a four-lane expressway south of Niles in the southwestern part of the state, and it runs concurrently with the Interstate 94 (I-94) freeway around the south side of Ypsilanti in the southeastern. In between Coldwater and the Ann Arbor area, the highway angles northeasterly and passes the Michigan International Speedway. East of Ypsilanti, US 12 follows a divided highway routing on Michigan Avenue into Detroit, where it terminates at an intersection with Cass Avenue.

When US 12 was designated in Michigan on November 11, 1926, along with the other original US Highways, it ran along a more northerly course. It originally replaced sections of the original M-11 and M-17 along Michigan Avenue in the state, the route of the much older St. Joseph Trail, a footpath used by Native Americans before European settlement in the area. It entered from Indiana as it does now, but it followed the Lake Michigan shoreline farther north to Benton Harbor–St. Joseph before turning eastward to run through Kalamazoo, Battle Creek and Jackson. In the Ann Arbor area, it followed a more northerly path into Detroit before terminating downtown. In the 1940s and 1950s, sections of the highway were converted into expressways and freeways. Starting in 1959, these freeway segments were renumbered as part of I-94, and in January 1962, US 12 was shifted to replace US Highway 112 (US 112). That highway, when it was designated in 1926 replaced the original M-23 along the Chicago Road, which was the route of the older Sauk Trail. Later, US 112 replaced the first M-151 when the former was extended to New Buffalo in the mid-1930s. Since 1962, the highway has remained relatively unchanged aside from minor truncations in the city of Detroit. US 112 previously had two business loops, both of which were renumbered Business US 12 (Bus. US 12) in 1962. In 2010, the Niles business loop was decommissioned, but the one in Ypsilanti remains. One section of the former US 112 was renumbered US 112S for a few years in the 1930s.

Route description

Between the state line near Michiana and the interchange with I-94 near New Buffalo, US 12 forms a portion of the Lake Michigan Circle Tour (LMCT). The full length of the highway in the state is also a Pure Michigan Historic Byway.[3] Outside of the various cities, most of US 12 is a rural, two-lane state highway. One section runs concurrently with I-94 south of Ypsilanti. From there eastward, US 12 is a divided highway and then a boulevard into the Detroit area.[4] The entire length of the highway east of Coldwater is listed on the National Highway System,[5] a network of roads important to the US's economy, defense, and mobility.[6]

Southwest Michigan

US 12 enters the state of Michigan southwest of New Buffalo near the town of Michiana. The highway runs a bit inland and parallel to the Lake Michigan shore on Red Arrow Highway past the community of Grand Beach before turning eastward away from the lake on the north side of New Buffalo. US 12 intersects I-94 less than a mile east of this turn and continues due east along Pulaski Highway through rural farmland. The highway is the main east–west street as it crosses through Three Oaks in southern Berrien County. East of Galien, the highway dips southward around Dayton Lake before passing south of Buchanan. The highway continues eastward, intersecting US 31 (St. Joseph Valley Parkway) near Niles. East of that freeway, US 12 expands into an expressway as the Niles Bypass. This bypass intersects M-139, crosses the St. Joseph River and intersects M-51 on the south side of Niles. US 12 turns northeasterly along the bypass east of downtown and then departs to the southeast at an interchange with Main Street and M-60 just across the county line with Cass County.[3][4]

Continuing through southern Cass County, US 12 runs roughly parallel to the state line. It turns northeasterly to run into Edwardsburg, where it intersects M-62. The highway turns southeasterly and runs to the south of Eagle Lake before entering the community of Adamsville. The highway continues on this southeasterly course until it intersects the former M-205 and M-217 (Michiana Parkway) near Union and turns to the northeast. US 12 intersects the southern end of M-40 before crossing into St. Joseph County at the eastern crossing of the St. Joseph River.[3][4]

On the eastern side of the river, US 12 enters Mottville and intersects M-103. The highway continues as Chicago Road through farmland and intersects US 131 near White Pigeon. It runs along the south side of Klinger Lake and continues to a junction with M-66 in Sturgis; the two highways run concurrently for about eight blocks through town. East of Sturgis, US 12 turns northeasterly into Branch County. Still named Chicago Road, it passes through Bronson and past Batavia. Northeast of Batavia, US 12 intersects the eastern end of M-86 near Branch County Memorial Airport. The airport is on the western edge of Coldwater, and after crossing the Coldwater River between Cemetery and South lakes, the highway runs through residential neighborhoods and into downtown. East of Division Street, Business Loop I-69 (BL I-69) follows US 12 through downtown and out to an interchange with I-69 on the east side of Coldwater. The highway continues past retail businesses and parallel to the Sauk River. US 12 passes through the town of Quincy before crossing into Hillsdale County.[3][4]

Southeast Michigan

East of the Hillsdale County line, US 12 runs easterly into Allen, where it intersects M-49. The highway continues northeastward through farmland to Jonesville, where it runs concurrently with M-99 through downtown and across a different St. Joseph River. The trunkline continues northeasterly through northern Hillsdale County, crossing the South Branch of the Kalamazoo River in Moscow. US 12 runs along the south side of Lake LeAnn in Somerset Center in the northeastern corner of the county. East of Somerset, the highway crosses into northern Lenawee County.[3][4]

Immediately east of the Lenawee County line, US 12 intersects US 127 in the Irish Hills region. South of Brooklyn in Cambridge Junction, it passes the Michigan International Speedway and crosses the River Raisin next to a junction with M-50. East of the racetrack, the highway meanders through an area dotted by several smaller lakes until it intersects M-124 at Walter J. Hayes State Park. Continuing as Michigan Avenue, US 12 angles northeasterly from the park until it hits the Lenawee–Washtenaw county line. The highway follows the line for several miles before reentering Lenawee County. It continues through an intersection with M-52 and into Clinton before turning northeasterly and fully crossing into Washtenaw County.[3][4]

In Washtenaw County, US 12 passes through Benton in a rural southern section of the county.[3] At Saline, the highway enters the suburban edge of the Ann Arbor–Ypsilanti metro area. US 12 follows Michigan Avenue northeasterly through Saline and across an interchange with US 23 before intersecting I-94 in Pittsfield and Ypsilanti townships. US 12 leaves Michigan Avenue to follow I-94 at that freeway's exit 181; Michigan Avenue continues into downtown Ypsilanti as a city street. I-94/US 12 skirts around the south side of the city and intersects the western end of Business US 12 (Bus. US 12) at Huron Street south of downtown. The freeway continues around the south side of the city and rounds the north end of Ford Lake. It is bounded by residential neighborhoods, and it crosses the Huron River on the eastern side of Ypsilanti. Near the Willow Run industrial complex and airport, US 12 separates from I-94 and turns northeasterly along an expressway on the north side of the airport. There are three interchanges, including one for the eastern end of M-17 before US 12 crosses into Wayne County and intersects the eastern end of Bus. US 12.[4][7]

East into Detroit

Once US 12 intersects the eastern end of its business loop, it returns to Michigan Avenue for the remainder of its routing in the state. The roadway is a boulevard in this area, a street divided by a central median. It runs through Canton Township and parallel to the Lower River Rouge. US 12 intersects I-275 on the eastern side of the township before crossing into Wayne. The highway is bounded by a mix of industrial and commercial properties in suburban Metro Detroit. In downtown Wayne, the two sides of Michigan Avenue split apart, surrounding the central business district of the city and separated by two to three city blocks. East of this split, Michigan Avenue crosses a section of Westland before entering Inkster.[4][7]

 
Historic Michigan Central Station along Michigan Avenue

In Dearborn, US 12 intersects US 24 (Telegraph Road) at an interchange on the western side of the city, and M-39 (Southfield Freeway) on the eastern side near the River Rouge crossing and Greenfield Village. On the Dearborn–Detroit city border, US 12 pass through a complex interchange with I-94 (Edsel Ford Freeway) and M-153 (Ford Road/Wyoming Avenue). Michigan Avenue continues northeasterly parallel to I-94 for a short distance before it turns due east.[4][7] Once it makes the direction change, it forms the 0 Mile of Detroit's Mile Road System.[8] US 12 continues through residential areas on Detroit's West Side, passing through the interchange that connects I-75 with I-96's eastern terminus near the Ambassador Bridge. The highway runs through Corktown and beside the site of the former Tiger Stadium at the corner of Michigan and Trumbull. East of the former stadium, US 12 crosses M-10 (Lodge Freeway) near the MGM Grand Detroit casino. East of M-10, Michigan Avenue enters Downtown Detroit. At the corner of Michigan and Cass, US 12 ends while Michigan Avenue continues several blocks further to terminate at Campus Martius Park at Woodward Avenue.[4][7]

History

Before 1926

 
Map of the pre-statehood Indian trails

The first major overland transportation corridors in the future state of Michigan were the Indian trails.[9] Two of these trails are relevant to US 12. The St. Joseph Trail ran between the Benton Harbor–St. Joseph area and Detroit by way of what is now Kalamazoo, Battle Creek, Jackson and Ann Arbor. The second, the Sauk Trail, ran further south through what is now Niles, and Coldwater to the Ann Arbor area.[10]

The Town of Detroit[a] created 120-foot-wide (37 m) rights-of-way for the principal streets of the city in 1805, including Michigan Avenue.[12] This street plan was devised by Augustus Woodward and others following a devastating fire in Detroit,[13] with a mandate from the territorial governor to improve on the previous plan.[14] The wide width of the avenues was an emulation of the street plan for Washington, DC, and intended to make Detroit the "Paris of the West".[15]

The southern of these two Indian trails later became the Chicago Road. Father Gabriel Richard, the first priest to serve in the U.S. House of Representatives, petitioned Congress to fund a highway between Detroit and Chicago in March 1824. A year later, the road was established in federal law, and it was surveyed by the end of 1825. Construction started in 1829, and the road was finished across Michigan in 1833.[16] The northern Indian trail was established as an unnamed territorial road (later called Territorial Road) in 1829.[17]

The State Trunkline Highway System was created on May 13, 1913, by an act of the Michigan Legislature; at the time, two of the system's divisions corresponded to the original US 12. Division 5 had a segment from New Buffalo to Benton Harbor and Watervliet while Division 6 connected Watervliet through Kalamazoo, Jackson and Ann Arbor to Detroit. No divisions corresponded to the future US 112.[18] In 1919, the Michigan State Highway Department (MSHD)[b] signposted the highway system for the first time,[21] and the future US 12 corridor was assigned two numbers. From the state line north through Benton Harbor to Watervliet, it carried the original M-11 designation, and from Watervliet eastward it was the original M-17. From Dearborn into Detroit, the original M-10 ran concurrently along M-17.[22]

The future US 112 along the Chicago Road had two different numbers in the original highway plan. Between New Buffalo and Niles, the highway was numbered M-60, and from Union to Ypsilanti, it was M-23. East of Ypsilanti, the corridor was part of M-17 and M-10. In November 1926, these two highway corridors were renumbered as part of the United States Numbered Highway System.[23]

Original US Highway: 1926–62

On November 11, 1926, the United States Numbered Highway System was approved by the American Association of State Highway Officials (AASHO),[2][c] and US 12 was the designation assigned to a highway running northeasterly from Indiana near Lake Michigan to Benton Harbor–St. Joseph and turning east to Detroit through Kalamazoo, Jackson, and Ann Arbor.[23] This designation replaced sections of the original M-11 and M-17 through the southern part of the state.[25][26] By the end of the next year, the MSHD rerouted the highway between Sawyer and Stevensville,[27] and Downtown Stevensville was bypassed in 1928.[28][29] Additional work to fully bypass Stevensville was finished in 1929.[30][31]

In 1931, the original routing of US 12 along a section of Michigan Avenue between Kalamazoo and Comstock was renumbered US 12A, and a new routing along King Highway south of the original opened.[32][33] By 1936, another US 12A debuted in Battle Creek, and by the end of the year, the main highway was rerouted between Augusta and Battle Creek. Another new segment of highway opened that same year east of Jackson, bypassing Leoni and Grass Lake to the north.[34][35] This new bypass was extended eastward from Sylvan to bypass Chelsea to the south the following year, filling a gap in "super highway"[d] segments between Jackson and Ann Arbor.[36][37] The last routing change in the 1930s was the opening of Stadium Drive in Kalamazoo, after which US 12 was rerouted to follow it west of downtown.[38][39]

In 1940, a southern bypass of Battle Creek opened along Columbia Avenue, and the former routing through downtown on Michigan Avenue became a Business US 12 (Bus. US 12).[40][41] In late 1951 or early 1952, a northerly bypass of Jackson opened, and the former route through downtown on Michigan Avenue became another Bus. US 12.[42][43] By the next year, the western half of the Jackson bypass opened, including a bypass of Parma.[44][45] In 1954, a new bypass of Kalamazoo and Galesburg opened; US 12 was rerouted to follow the new highway while M-96 replaced part of the old route and the US 12A in the area.[46][47]

In 1956, several changes were made to US 12's routing. A southern bypass of Ann Arbor and Ypsilanti was converted to a freeway. US 12 was rerouted to follow the bypass, supplanting the M-17 and Bypass US 112 designations used previously on the bypass. US 112 was also rerouted, and it ran concurrently with US 12 along the bypass. The former route of US 12 along Plymouth Road from Ann Arbor east to Detroit was renumbered M-14, and the M-112 designation on the Willow Run and Detroit Industrial expressways was replaced by US 12. At the same time as these changes were made, the Jackson bypass was upgraded to a full freeway.[48][49] By the middle of 1958, the Kalamazoo bypass was converted to a full freeway.[50][51]

Previously delayed so that the designations could be finalized,[52] the MSHD started numbering its Interstate Highways in 1959, adding I-94 to the sections of US 12 freeway.[53] Later that year, additional segments of I-94/US 12 were opened, starting with a 10-mile (16 km) section from Hartford to Coloma, then another from Paw Paw to Kalamazoo which connected with a segment between Galesburg to Battle Creek. The overall 45-mile (72 km) section from Paw Paw to Battle Creek was dedicated on December 7, 1959.[54] By the middle of 1960, US 12 followed the I-94 freeway from Coloma to Watervliet and from Paw Paw to the east side of Jackson. It was also routed along the freeway from the west side of Ann Arbor into Detroit, where it followed the southern end of the Lodge Freeway.[55] By the middle of 1961, the Watervliet–Paw Paw and Jackson–Ann Arbor freeway gaps were completed, and the freeway was extended westward to Stevensville.[56] By the end of the year, I-94/US 12 extended all the way to New Buffalo.[57] In January 1962, the state made the biggest rerouting change of all to US 12: the designation was removed from the I-94 freeway from New Buffalo to Detroit and shifted to completely replace US 112.[58][59]

US Highway 112: 1926–62

In 1925, US 112 was originally proposed to run from Oshkosh to Fremont, Wisconsin, on what later became U.S. Route 110.[62] When it was initially designated in November 1926, US 112 made a sharp turn to the southwest to connect to US 20 in Elkhart, Indiana.[23] In 1931, a new trunkline highway was designated between M-60 at Niles and US 112 at Union. This highway was numbered M-151.[32][33] In 1933, the section of US 112 from Union to Elkhart was renumbered US 112S.[63][64] M-151 and US 112S each lasted until 1935 when US 112 was extended to replace M-151. US 112 was also extended to run concurrently with M-60 to New Buffalo, and US 112S was renumbered M-205.[60][61]

In 1936, the section of US 112 along Michigan Avenue east of Ypsilanti was expanded into a "super highway".[34][35] In 1955, a realignment of US 127 in southern Jackson County removed a short concurrency with US 112 from Somerset Center in Hillsdale County and the current intersection in northwestern Lenawee County.[65][66]

On December 1, 1956, the highway department opened the first 6.6 miles (10.6 km) of a new four-lane divided highway around the south side of Niles; the final 1.6 miles (2.6 km) of the bypass opened early the next year.[67] Consequently, they converted the former route through town back to US 112/M-60 into a business loop numbered Bus. US 112.[68][69] At the end of the decade, another highway concurrency was removed when US 131 was realigned to run directly south of US 112 to the state line instead of running concurrently along US 112 between Mottville and White Pigeon.[51][55] In January 1962, the US 112 designation was eliminated when US 12 was shifted off the I-94 freeway to replace US 112.[58][59] The state's rationale for the removal of the US 112 designation was the long-standing AASHO recommendation against US Highway designations extant in only one state.[70]

After 1962

After US 12 replaced US 112, the Bus. US 12 routes were renumbered as Business Loop I-94, and the two Bus. US 112s were renumbered to Bus. US 12.[57] In 1966, the state truncated M-60 and removed it as a concurrent designation along US 12 between New Buffalo and Niles.[71][72]

In October 2000, the state proposed changing jurisdiction of several highways near Campus Martius Park in Detroit,[73] and US 12 was shortened by four city blocks the next year to end along Michigan Avenue at Griswold Street.[74][75] This would be shortened again in 2005 to Michigan Avenue and Cass Avenue.[76][77]

In April 2017, MDOT announced the reconstruction of US 12 east of Ypsilanti, which would reduce the route from a boulevard to a singular road along the existing eastbound lanes. This project would also eliminate an interchange with Wiard Road and allow the adjacent American Center for Mobility to use the westbound lanes as part of a facility to test automated vehicles. The project was projected to be completed that November.[78][79]

Memorial highway and byway names

 
Iron Brigade Memorial Highway sign, Pittsfield Township

The roads that have carried US 12 in Michigan have been given a number of memorial highway names. In 1922, after the publication of Main Street by Sinclair Lewis that street name took on a pejorative connotation. The newspaper in Jackson advocated that the main road from Detroit to Chicago which formed the main street through many communities in southern Michigan should be given a new name. It was already labeled the Michigan–Detroit–Chicago Highway on travel maps of the time, so the paper suggested that the roadway should be renamed to create the longest street in the country. Both Chicago and Detroit had streets named Michigan Avenue, so that is what the newspaper suggested for a new name. Albion was the first community to change the name of its street followed by Jackson and Marshall in 1924, Battle Creek in 1928 and Kalamazoo in 1929.[17]

In 1952, US 12 was dedicated to the 32nd Infantry Division. The division used a red arrow as its insignia to symbolize how they pierced the German Hindenburg Line during World War I and Japanese defenses during World War II. The soldiers who composed the division were drawn from the Michigan and Wisconsin National Guards. After other proposals failed, US 12 was named the Red Arrow Highway on August 30, 1952, and dedicated on March 22, 1953. Jurisdiction of most of the roadways that composed US 12 at that time has passed to local governments as I-94 was built, but the highway still bears that name in Berrien County[80] and Van Buren County.[81]

Count Casimir Pulaski was a Polish-born noble and soldier who fought on the side of the Americans during the Revolutionary War. He was appointed a brigadier general on the recommendations of George Washington and later became known as the "Father of the American Cavalry". He was severely wounded during the siege of Savannah and died while being treated on the brigantine Wasp. The route of US 112 was designated the Pulaski Memorial Highway by Public Act 11 of 1953 and formally dedicated in Detroit on October 4, 1953. The segment of what is now US 12 in Berrien County still bears this name.[82]

US 12 has also been designated as the Iron Brigade Memorial Highway, a designation which it also has in Indiana,[83] Illinois[84] and Wisconsin.[85] The name honors the 24th Michigan Infantry Regiment, part of the Iron Brigade from the American Civil War. The regiment lost more troops than any other on the Union side during the war and provided the military escort for Abraham Lincoln's funeral in Springfield, Illinois. The unit traveled along the Chicago Road to join the war effort. The highway was dedicated in twin ceremonies in New Buffalo on October 9, 1994, and in Detroit on November 11, 1995, to the Iron Brigade.[86]

In 1986, the Michigan Department of Transportation consulted with its counterparts in Wisconsin (WisDOT), Minnesota (Mn/DOT) and Ontario (Ministry of Transportation of Ontario, MTO) about the formation of a circle tour around Lake Superior.[87] The Lake Michigan Circle Tour was signed on maps by 1988.[88] In May 2001, the section of US 12 through Saline was designated a Michigan Historic Heritage Route. The segment through Clinton was given the same status in October 2002.[16] On June 9, 2004, the full length of US 12 was dedicated as the US 12 Heritage Trail.[89] In December 2014, this became a Pure Michigan Byway when Governor Rick Snyder signed legislation renaming the Michigan Heritage Route System to the Pure Michigan Byway System.[90]

US Highway 12A (US 12A) was an alternate route of US 12 in the Kalamazoo area. The highway followed Michigan Avenue from Kalamazoo eastward along the north side of the Kalamazoo River to Comstock, where it terminated at an intersection with M-96. The highway was formed in 1931 when US 12 was rerouted in the area.[32][33] In 1954, the designation was decommissioned when M-96 was extended to Kalamazoo on the south side of the Kalamazoo River along King Highway.[46][47]

Business US Highway 12 (Bus. US 12) was a business route running in Niles. The western terminus was at the corner of West Chicago Road and US 12 (Pulaski Highway) east of the US 12/US 31 interchange. From there, the business loop followed Chicago Road northeasterly through residential areas on the west side of town. Bus. US 12 turned north along Lincoln Avenue and then east on Main Street, crossing the St. Joseph River. The loop intersected the southern end of M-139 at Front Street one block east of the river in downtown Niles. Four blocks further east, Bus. US 12 met M-51. The two highways merged along Main Street and then turned south along 11th Street at an intersection that also marks the western terminus of Bus. M-60 (Oak Street). Bus. US 12/M-51 continued south along 11th Street to the corner of US 12 (Pulaski Highway) and M-51 (South 11th Street) where the business loop terminated.[93][94]

The trunkline was first designated in 1956 as a business route of US 112. At that time, US 112 and M-60 were transferred to a bypass south of Niles.[68][69] When US 112 was decommissioned in January 1962,[58] Bus. US 112 was redesignated Bus. US 12 to match the new US 12 designation.[57] In 1986, US 33 was truncated in Michigan to end at US 12.[95] Bus. US 12 was rerouted in Niles to replace US 33 through town;[96][97] Bus. US 31 was added a year later when the signage was updated in the area.[97][98] In 1998, US 33 was removed from Michigan completely. At this time, M-51 was extended over former US 33 and replaced part of the Bus. US 31 designation in Niles.[99] On March 5, 2010, the segment of Bus. US 12 between Bus. US 31 and M-51 was turned over to local control.[92] In April 2010 the Bus. US 12 designation was retired when an extended M-139 replaced it from the local control section southwestward prior to maps and signage being changed.[100] The concurrent segment along M-51 became M-51 only.[101]

Major intersections
The entire highway was in St. Joseph County.

Business US Highway 12 (Bus. US 12) is a business route running in Ypsilanti. The loop starts at exit 183 on I-94/US 12 south of downtown Ypsilanti and runs northward along the one-way pairing of Huron Street (northbound) and Hamilton Street (southbound). At the intersection with Michigan Avenue in downtown, the two directions reunite and turn eastward, merging onto M-17 in the process. Michigan Avenue crosses the Huron River and continues due east until an intersection at Prospect Street where it turns northeasterly. M-17 separates from Bus. US 12 at Ecorse Road, and Michigan Avenue continues through commercial areas, exiting the city of Ypsilanti. Once Bus. US 12 crosses from Washtenaw County into Wayne County, it expands into a boulevard with Michigan left turns. Just north of the Willow Run industrial complex, Bus. US 12 terminates where US 12 merges onto Michigan Avenue.[104][105]

 
Michigan Avenue facing west, downtown Ypsilanti

In 1942 or 1943, Ypsilanti was bypassed by a Bypass US 112 (Byp. US 112). US 112 continued to run along its routing in Ypsilanti.[102][103] The first business loop in Ypsilanti was created in 1956 when US 112 was realigned to bypass downtown along the former Byp. US 112. The former route through downtown was then numbered Bus. US 112.[48][49] The current designation was changed to Bus. US 12 in 1962 when US 12 replaced US 112.[58]

US Highway 112S (US 112S) was a spur route of US 112 in the mid-1930s. Originally, US 112 turned southward at Union and ran to US 20 in Elkhart, Indiana. In 1933, this section of highway was renumbered US 112S,[63][64] before US 112 was relocated to go through Michigan's southwesternmost counties in 1935. At the same time, US 112S was renumbered M-205,[60][61] a designation it would hold until it was transferred to local control on October 10, 2002,[107] decommissioning the trunkline.[108][109]

150M 151 M 151When US 12 was designated in Michigan on November 11 1926 along with the other original US Highways it ran along a more northerly course It originally replaced sections of the original M 11 and M 17 along Michigan Avenue in the state the route of the much older St Joseph Trail a footpath used by Native Americans before European settlement in the area It entered from Indiana as it does now but it followed the Lake Michigan shoreline farther north to Benton Harbor St Joseph before turning eastward to run through Kalamazoo Battle Creek and Jackson In the Ann Arbor area it followed a more northerly path into Detroit before terminating downtown In the 1940s and 1950s sections of the highway were converted into expressways and freeways Starting in 1959 these freeway segments were renumbered as part of I 94 and in January 1962 US 12 was shifted to replace US Highway 112 US 112 That highway when it was designated in 1926 replaced the original M 23 along the Chicago Road which was the route of the older Sauk Trail Later US 112 replaced the first M 151 when the former was extended to New Buffalo in the mid 1930s Since 1962 the highway has remained relatively unchanged aside from minor truncations in the city of Detroit US 112 previously had two business loops both of which were renumbered Business US 12 Bus US 12 in 1962 In 2010 the Niles business loop was decommissioned

Indian trails The first major overland transportation corridors in the future state of Michigan were the Indian trails 9 Two of these trails are relevant to US 12 The St Joseph Trail ran between the Benton Harbor St Joseph area and Detroit by way of what is now Kalamazoo Battle Creek Jackson and Ann Arbor The second the Sauk Trail ran further south through what is now Niles and Coldwater to the Ann Arbor area 10 The Town of Detroit a created 120 foot wide 37 m rights of way for the principal streets of the city in 1805 including Michigan Avenue 12 This street plan was devised by Augustus Woodward and others following a devastating fire in Detroit 13 with a mandate from the territorial governor to improve on the previous plan 14 The wide width of the avenues was an emulation of the street plan for Washington DC and intended to make Detroit the Paris of the West 15 The southern of these two Indian trails later became the Chicago Road Father Gabriel Richard the first priest to serve in the U S House of Representatives petitioned Congress to fund a highway between Detroit and Chicago in March 1824 A year later the road was established in federal law and it was surveyed by the end of 1825 Construction started in 1829 and the road was finished across Michigan in 1833 16 The northern Indian trail was established as an unnamed territorial road later called Territorial Road in 1829 17 The State Trunkline Highway System was created on May 13 1913 by an act of the Michigan Legislature at the time two of the system s divisions corresponded to the original US 12 Division 5 had a segment from New Buffalo to Benton Harbor and Watervliet while Division 6 connected Watervliet through Kalamazoo Jackson and Ann Arbor to Detroit No divisions corresponded to the future US 112 18 In 1919 the Michigan State Highway Department MSHD b signposted the highway system for the first time 21 and the future US 12 corridor was assigned two numbers From the state line north through Benton Harbor to Watervliet it carried the original M 11 designation and from Watervliet eastward it was the original M 17 From Dearborn into Detroit the original M 10 ran concurrently along M 17 22 M 23LocationUnion YpsilantiLength130 223 mi 1 209 574 km Existedc July 1 1919 22 November 11 1926 23 The future US 112 along the Chicago Road had two different numbers in the original highway plan Between New Buffalo and Niles the highway was numbered M 60 and from Union to Ypsilanti it was M 23 East of Ypsilanti the corridor was part of M 17 and M 10 In November 1926 these two highway corridors were renumbered as part of the United States Numbered Highway System 23 Original US Highway 1926 62 Edit On November 11 1926 the United States Numbered Highway System was approved by the American Association of State Highway Officials AASHO 2 c and US 12 was the designation assigned to a highway running northeasterly from Indiana near Lake Michigan to Benton Harbor St Joseph and turning east to Detroit through Kalamazoo Jackson and Ann Arbor 23 This designation replaced sections of the original M 11 and M 17 through the southern part of the state 25 26 By the end of the next year the MSHD rerouted the highway between Sawyer and Stevensville 27 and Downtown Stevensville was bypassed in 1928 28 29 Additional work to fully bypass Stevensville was finished in 1929 30 31 In 1931 the original routing of US 12 along a section of Michigan Avenue between Kalamazoo and Comstock was renumbered US 12A and a new routing along King Highway south of the original opened 32 33 By 1936 another US 12A debuted in Battle Creek and by the end of the year the main highway was rerouted between Augusta and Battle Creek Another new segment of highway opened that same year east of Jackson bypassing Leoni and Grass Lake to the north 34 35 This new bypass was extended eastward from Sylvan to bypass Chelsea to the south the following year filling a gap in super highway d segments between Jackson and Ann Arbor 36 37 The last routing change in the 1930s was the opening of Stadium Drive in Kalamazoo after which US 12 was rerouted to follow it west of downtown 38 39 In 1940 a southern bypass of Battle Creek opened along Columbia Avenue and the former routing through downtown on Michigan Avenue became a Business US 12 Bus US 12 40 41 In late 1951 or early 1952 a northerly bypass of Jackson opened and the former route through downtown on Michigan Avenue became another Bus US 12 42 43 By the next year the western half of the Jackson bypass opened including a bypass of Parma 44 45 In 1954 a new bypass of Kalamazoo and Galesburg opened US 12 was rerouted to follow the new highway while M 96 replaced part of the old route and the US 12A in the area 46 47 Tiger Stadium former home of the Detroit Tigers at the corner of Michigan and Trumbull in Detroit now demolished In 1956 several changes were made to US 12 s routing A southern bypass of Ann Arbor and Ypsilanti was converted to a freeway US 12 was rerouted to follow the bypass supplanting the M 17 and Bypass US 112 designations used previously on the bypass US 112 was also rerouted and it ran concurrently with US 12 along the bypass The former route of US 12 along Plymouth Road from Ann Arbor east to Detroit was renumbered M 14 and the M 112 designation on the Willow Run and Detroit Industrial expressways was replaced by US 12 At the same time as these changes were made the Jackson bypass was upgraded to a full freeway 48 49 By the middle of 1958 the Kalamazoo bypass was converted to a full freeway 50 51 Previously delayed so that the designations could be finalized 52 the MSHD started numbering its Interstate Highways in 1959 adding I 94 to the sections of US 12 freeway 53 Later that year additional segments of I 94 US 12 were opened starting with a 10 mile 16 km section from Hartford to Coloma then another from Paw Paw to Kalamazoo which connected with a segment between Galesburg to Battle Creek The overall 45 mile 72 km section from Paw Paw to Battle Creek was dedicated on December 7 1959 54 By the middle of 1960 US 12 followed the I 94 freeway from Coloma to Watervliet and from Paw Paw to the east side of Jackson It was also routed along the freeway from the west side of Ann Arbor into Detroit where it followed the southern end of the Lodge Freeway 55 By the middle of 1961 the Watervliet Paw Paw and Jackson Ann Arbor freeway gaps were completed and the freeway was extended westward to Stevensville 56 By the end of the year I 94 US 12 extended all the way to New Buffalo 57 In January 1962 the state made the biggest rerouting change of all to US 12 the designation was removed from the I 94 freeway from New Buffalo to Detroit and shifted to completely replace US 112 58

112 made a sharp turn to the southwest to connect to US 20 in Elkhart Indiana 23 In 1931 a new trunkline highway was designated between M 60 at Niles and US 112 at Union This highway was numbered M 151 32 33 In 1933 the section of US 112 from Union to Elkhart was renumbered US 112S 63 64 M 151 and US 112S each lasted until 1935 when US 112 was extended to replace M 151 US 112 was also extended to run concurrently with M 60 to New Buffalo and US 112S was renumbered M 205 60 61 In 1936 the section of US 112 along Michigan Avenue east of Ypsilanti was expanded into a super highway 34 35 In 1955 a realignment of US 127 in southern Jackson County removed a short concurrency with US 112 from Somerset Center in Hillsdale County and the current intersection in northwestern Lenawee County 65 66 On December 1 1956 the highway department opened the first 6 6 miles 10 6 km of a new four lane divided highway around the south side of Niles the final 1 6 miles 2 6 km of the bypass opened early the next year 67 Consequently they converted the former route through town back to US 112 M 60 into a business loop numbered Bus US 112 68 69 At the end of the decade another highway concurrency was removed when US 131 was realigned to run directly south of US 112 to the state line instead of running concurrently along US 112 between Mottville and White Pigeon 51 55 In January 1962 the US 112 designation was eliminated when US 12 was shifted off the I 94 freeway to replace US 112 58 59 The state s rationale for the removal of the US 112 designation was the long standing AASHO recommendation against US Highway designations extant in only one state 70 After 1962 Edit After US 12 replaced US 112 the Bus US 12 routes were renumbered as Business Loop I 94 and the two Bus US 112s were renumbered to Bus US 12 57 In 1966 the state truncated M 60 and removed it as a concurrent designation along US 12 between New Buffalo and Niles 71 72 In October 2000 the state proposed changing jurisdiction of several highways near Campus Martius Park in Detroit 73 and US 12 was shortened by four city blocks the next year to end along Michigan Avenue at Griswold Street 74 75 This would be shortened again in 2005 to Michigan Avenue and Cass Avenue 76 77 In April 2017 MDOT announced the reconstruction of US 12 east of Ypsilanti which would reduce the route from a boulevard to a singular road along the existing eastbound lanes This project would also eliminate an interchange with Wiard Road and allow the adjacent American Center for Mobility to use the westbound lanes as part of a facility to test automated vehicles The project was projected to be completed that November 78 79 Memorial highway and byway names Edit Iron Brigade Memorial Highway sign Pittsfield Township The roads that have carried US 12 in Michigan have been given a number of memorial highway names In 1922 after the publication of Main Street by Sinclair Lewis that street name took on a pejorative connotation The newspaper in Jackson advocated that the main road from Detroit to Chicago which formed the main street through many communities in southern Michigan should be given a new name It was already labeled the Michigan Detroit Chicago Highway on travel maps of the time so the paper suggested that the roadway should be renamed to create the longest street in the country Both Chicago and Detroit had streets named Michigan Avenue so that is what the newspaper suggested for a new name Albion was the first community to change the name of its street followed by Jackson and Marshall in 1924 Battle Creek in 1928 and Kalamazoo in 1929 17 In 1952 US 12 was dedicated to the 32nd Infantry Division The division used a red arrow as its insignia to symbolize how they pierced the German Hindenburg Line during World War I and Japanese defenses during World War II The soldiers who composed the division were drawn from the Michigan and Wisconsin National Guards After other proposals failed US 12 was named the Red Arrow Highway on August 30 1952 and dedicated on March 22 1953 Jurisdiction of most of the roadways that composed US 12 at that time has passed to local governments as I 94 was built but the highway still bears that name in Berrien County 80 and Van Buren County 81 Count Casimir Pulaski was a Polish born noble and soldier who fought on the side of the Americans during the Revolutionary War He was appointed a brigadier general on the recommendations of George Washington and later became known as the Father of the American Cavalry He was severely wounded during the siege of Savannah and died while being treated on the brigantine Wasp The route of US 112 was designated the Pulaski Memorial Highway by Public Act 11 of 1953 and formally dedicated in Detroit on October 4 1953 The segment of what is now US 12 in Berrien County still bears this name 82 US 12 has also been designated as the Iron Brigade Memorial Highway a designation which it also has in Indiana 83 Illinois 84 and Wisconsin 85 The name honors the 24th Michigan Infantry Regiment part of the Iron Brigade from the American Civil War The regiment lost more troops than any other on the Union side during the war and provided the military escort for Abraham Lincoln s funeral in Springfield Illinois The unit traveled along the Chicago Road to join the war effort The highway was dedicated in twin ceremonies in New Buffalo on October 9 1994 and in Detroit on November 11 1995 to the Iron Brigade 86 In 1986 the Michigan Department of Transportation consulted with its counterparts in Wisconsin WisDOT Minnesota Mn DOT and Ontario Ministry of Transportation of Ontario MTO about the formation of a circle tour around Lake Superior 87 The Lake Michigan Circle Tour was signed on maps by 1988 88 In May 2001 the section of US 12 through Saline was designated a Michigan Historic Heritage Route The segment through Clinton was given the same status in October 2002 16 On June 9 2004 the full length of US 12 was dedicated as the US 12 Heritage Trail 89 In December 2014 this became a Pure Michigan Byway when Governor Rick Snyder signed legislation renaming the Michigan Heritage Route System to the Pure Michigan Byway System 90 Major intersections EditCountyLocationmi 1 kmExitDestinationsNotesBerrienNew Buffalo Township0 0000 000 US 12 west LMCT west Michigan
