List of Interstate Highways in Michigan

October 15, 2023

The Interstate Highways in Michigan are the segments of the national Dwight D. Eisenhower System of Interstate and Defense Highways[3] that are owned and maintained by the U.S. state of Michigan,[4] totaling about 1,239 miles (1,994 km).[2] The longest of these, Interstate 75 (I-75), is also the longest highway of any kind in the state.[5] On a national level, the standards and numbering for the system are handled by the Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO), while the highways in Michigan are maintained by the Michigan Department of Transportation (MDOT) and the Mackinac Bridge Authority (MBA). The Interstates in Michigan have their origins in World War II-era expressways built in the Detroit area. After the system was created in 1956, the state highway department completed its first border-to-border Interstate in 1960. The last highway was completed in 1992, giving Michigan a total of 13 Interstate freeways. The original allotment of mileage to Michigan which would receive federal funding was expanded in 1968, and the United States Congress designated an additional highway in the 1990s that has not yet been built.

There are also 26 current business routes that connect cities bypassed by the Interstates; 23 are business loops that connect on both ends to their parent highway, and three are business spurs that connect on only one end. I-496 has the Capitol Loop as its connection to the Michigan State Capitol in downtown Lansing. Another six business routes have been designated but are either no longer signed or maintained as state highways.

Description Edit

MDOT is the agency responsible for the day-to-day maintenance and operations of the State Trunkline Highway System, which includes the Interstate Highways in Michigan. These highways are built to Interstate Highway standards,[6] meaning they are all freeways with minimum requirements for full control of access, design speeds of 50 to 70 miles per hour (80 to 113 km/h) depending on type of terrain, a minimum of two travel lanes in each direction, and specific widths of lanes or shoulders;[7] exceptions from these standards have to be approved by the FHWA.[8] The numbering scheme used to designate the Interstates was developed by AASHTO, an organization composed of the various state departments of transportation in the United States.[9]

The Interstate Highway System covers about 1,240 miles (2,000 km) in the state and consists of four primary highways and nine auxiliary highways. There are additional 29 business routes associated with the system in Michigan. The longest segment of Interstate Highway in the state is Interstate 75 (I-75) at just under 396 miles (637 km); the shortest is I-375 at 1.1 miles (1.8 km). The length of I-75, the longest highway of any kind in the state,[5] includes the Mackinac Bridge, which is maintained by the MBA, the only section of state highway not under MDOT jurisdiction.[a] The Mackinac Bridge is one of three monumental bridges in the state used by I-75; the others are the Zilwaukee and International bridges. A fourth, the privately owned Ambassador Bridge connects I-75 and I-96 in Detroit to Canada.[11]

History Edit

Construction of the first expressways in Michigan predates the Interstate Highway System. During World War II, the Michigan State Highway Department (MSHD)[b] built the Willow Run and Detroit Industrial expressways (now part of I-94) to carry workers from Detroit to the defense plants at Willow Run Airport.[14] The state created the Michigan Turnpike Authority (MTA) in 1951,[15] which proposed the construction of a toll freeway to run north–south in the state. The original termini for the Michigan Turnpike were Bridgeport and Rockwood.[16] Interagency politics stalled progress on any proposed turnpikes[17] while MSHD had three freeways under planning or construction.[18]

 
1958 planning map for Michigan's Interstate Highways

The Interstate Highway System was authorized by the Federal Aid Highway Act of 1956,[1] and the state had already designed several freeways for its portion of that system. Seizing the opportunity brought by a 1957 state law, the department sold $700 million in bonds (equivalent to $5.24 billion in 2011[19]) in the late 1950s and early 1960s to finance land purchases and construction of the new freeways. The goal was to connect every city with a population over 50,000 with four-lane freeways that could accommodate rural traffic traveling at 70 mph (110 km/h).[18] The MSHD delayed numbering these freeways as part of the Interstate Highway System until the federal government had finalized the designations to be assigned to Michigan's freeways.[20] The first highway to be signed as an Interstate in Michigan was I-75, which received signage in late 1959, along a section near the Ohio state line that opened to traffic in October 1957.[21][22] I-94 was the first of the Interstates to be completed border to border in a US state.[23] In 1974, the state implemented mileage-based exit numbers along the Interstates in Michigan.[24]

The MSHD asked for 600 miles (970 km) in additions to the state's Interstate mileage in 1968. Included in these requests were the extension of the Davison Freeway (now M-8), the extension of I-69 from Marshall to Port Huron, and the conversion of the northern sections of US Highway 23 (US 23) and US 131.[25] Of these, the I-69 proposal was approved when the United States Congress extended it to terminate in at I-75 in Flint. The highway was lengthened twice more: to I-475 in 1973 and to Port Huron on February 10, 1987.[26] These last two extensions were classified non-chargeable mileage, or segments not financed through the Interstate Highway fund.[27] The federal government paid 90 percent of the cost of the chargeable mileage originally approved.[18]

The last of Michigan's Interstates to be completed was I-69, the last segment of which opened in 1992.[28] Since then, the United States Congress has designated an additional primary Interstate, I-73 in the state. All studies by MDOT on that highway were cancelled in 2001 over funding concerns.[29] Press reports state there is a "lack of need" for the freeway in the state,[30] and the department has no plans to revive I-73 as of 2011.[31] If built as designated, I-73 would cross into Michigan near Toledo, Ohio, and connect Jackson, Lansing, and Clare to I-75 at Grayling.[32]

Notes Edit

  1. ^ The Mackinac Bridge Authority (MBA) is an independent state agency responsible for the Mackinac Bridge and thus maintains that section of the overall highway system. The MBA works with MDOT but does not report to it. The executive secretary of the MBA is appointed by MDOT with MBA approval.[10]
  2. ^ The Michigan State Highway Department was reorganized into the Michigan Department of State Highways and Transportation on August 23, 1973,[12] and the name was later shortened to its current form in 1978.[13]
  3. ^ When the MSHD was planning the freeway network in the state, they called all of the auxiliary Interstate Highways, "Penetrator"[43]
  4. ^ The legislation defining the I-73 corridor specifies Sault Ste. Marie and Detroit as the northern termini, but the Grayling–Sault Ste. Marie or Toledo–Detroit segments overlap I-75 with no requirement to overlap the highway designations. Similarly, Congress included I-94 between Chicago and Port Huron in the I-69 corridor to make it eligible for funding.[32]
  5. ^ The section of Jefferson Avenue that connects I-375 with M-10 is combined with the freeway as I-375 on MDOT right-of-way (ROW) maps that document property transfers and ROW descriptions,[99] but in the department's Physical Reference Finder Application, the street is marked as BS I-375,[2] a designation missing from the official state map for the public.[100]

The Interstate Highways in Michigan are the segments of the national Dwight D Eisenhower System of Interstate and Defense Highways 3 that are owned and maintained by the U S state of Michigan 4 totaling about 1 239 miles 1 994 km 2 The longest of these Interstate 75 I 75 is also the longest highway of any kind in the state 5 On a national level the standards and numbering for the system are handled by the Federal Highway Administration FHWA and the American Association of State Highway and Transportation Officials AASHTO while the highways in Michigan are maintained by the Michigan Department of Transportation MDOT and the Mackinac Bridge Authority MBA The Interstates in Michigan have their origins in World War II era expressways built in the Detroit area After the system was created in 1956 the state highway department completed its first border to border Interstate in 1960 The last highway was completed in 1992 giving Michigan a total of 13 Interstate freeways The original allotment of mileage to Michigan which would receive federal funding was expanded in 1968 and the United States Congress designated an additional highway in the 1990s that has not yet been

operations of the State Trunkline Highway System which includes the Interstate Highways in Michigan These highways are built to Interstate Highway standards 6 meaning they are all freeways with minimum requirements for full control of access design speeds of 50 to 70 miles per hour 80 to 113 km h depending on type of terrain a minimum of two travel lanes in each direction and specific widths of lanes or shoulders 7 exceptions from these standards have to be approved by the FHWA 8 The numbering scheme used to designate the Interstates was developed by AASHTO an organization composed of the various state departments of transportation in the United States 9 The Interstate Highway System covers about 1 240 miles 2 000 km in the state and consists of four primary highways and nine auxiliary highways There are additional 29 business routes associated with the system in Michigan The longest segment of Interstate Highway in the state is Interstate 75 I 75 at just under 396 miles 637 km the shortest is I 375 at 1 1 miles 1 8 km The length of I 75 the longest highway of any kind in the state 5 includes the Mackinac Bridge which is maintained by the MBA the only section of state highway not under MDOT jurisdiction a The Mackinac Bridge is one of three monumental bridges in the state used by I 75 the others are the Zilwaukee and International bridges A fourth the privately owned Ambassador Bridge connects I 75 and I 96 in Detroit to Canada 11 History EditConstruction of the first expressways in Michigan predates the Interstate Highway System During World War II the Michigan State Highway Department MSHD b built the Willow Run and Detroit Industrial expressways now part of I 94 to carry workers from Detroit to the defense plants at Willow Run Airport 14 The state created the Michigan Turnpike Authority MTA in 1951 15 which proposed the construction of a toll freeway to run north south in the state The original termini for the Michigan Turnpike were Bridgeport and Rockwood 16 Interagency politics stalled progress on any proposed turnpikes 17 while MSHD had three freeways under planning or construction 18 nbsp 1958 planning map for Michigan s Interstate HighwaysThe Interstate Highway System was authorized by the Federal Aid Highway Act of 1956 1 and the state had already designed several freeways for its portion of that system Seizing the opportunity brought by a 1957 state law the department sold 700 million in bonds equivalent to 5 24 billion in 2011 19 in the late 1950s and early 1960s to finance land purchases and construction of the new freeways The goal was to connect every city with a population over 50 000 with four lane freeways that could accommodate rural traffic traveling at 70 mph 110 km h 18 The MSHD delayed numbering these freeways as part of the Interstate Highway System until the federal government had finalized the designations to be assigned to Michigan s freeways 20 The first highway to be signed as an Interstate in Michigan was I 75 which received signage in late 1959 along a section near the Ohio state line that opened to traffic in October 1957 21 22 I 94 was the first of the Interstates to be completed border to border in a US state 23 In 1974 the state implemented mileage based exit numbers along the Interstates in Michigan 24 The MSHD asked for 600 miles 970 km in additions to the state s Interstate mileage in 1968 Included in these requests were the extension of the Davison Freeway now M 8 the extension of I 69 from Marshall to Port Huron and the conversion of the northern sections of US Highway 23 US 23 and US 131 25 Of these the I 69 proposal was approved when the United States Congress extended it to terminate in at I 75 in Flint The highway was lengthened twice more to I 475 in 1973 and to Port Huron on February 10 1987 26 These last two extensions were classified non chargeable mileage or segments not financed through the Interstate Highway fund 27 The federal government paid 90 percent of the cost of the chargeable mileage originally approved 18 The last of Michigan s Interstates to be completed was I 69 the last segment of which opened in 1992 28 Since then the United States Congress has designated an additional primary Interstate I 73 in the state All studies by MDOT on that highway were cancelled in 2001 over funding concerns 29 Press reports state there is a lack of need for the freeway in the state 30 and the department has no plans to revive I 73 as of 2011 31 If built as designated I 73 would cross into Michigan near Toledo Ohio and connect
