List of former Maryland state highways (400–499)

The Maryland highway system has several hundred former state highways. These highways were constructed, maintained, or funded by the Maryland State Roads Commission or Maryland State Highway Administration and assigned a unique or temporally unique number. Sometime after the highway was assigned, the highway was transferred to county or municipal maintenance and the number designation was removed from the particular stretch of road. In some cases, a highway was renumbered in whole or in part. This list contains all or most of the state-numbered highways between 400 and 499 that have existed since highways were first numbered in 1927 but are no longer part of the state highway system or are state highways of a different number. Most former state highways have not had their numbers reused. However, many state highway numbers were used for a former highway and are currently in use. Some numbers have been used three times. The former highways below whose numbers are used presently, those that were taken over in whole or in part by another highway, or have enough information to warrant a separate article contain links to those separate highway articles. Highway numbers that have two or more former uses are differentiated below by year ranges. This list does not include former Interstate or U.S. Highways, which are linked from their respective lists.

Maryland Route 447 was the designation for Old Locust Grove Road, which ran 0.84 miles (1.35 km) from MD 213 northwest to MD 444 at Locust Grove in northern Kent County.^{[MD 447 L 1]} The roads on which MD 447 ran were built in two sections. The portion from US 213 to Shallcross Wharf Road and Shallcross Wharf Road west from Locust Grove were part of the original Chestertown–Galena highway proposed for improvement as a state road in 1909.^{[MD 447 L 2]} This stretch was constructed as a 12-foot-wide (3.7 m) macadam road in 1913.^{[MD 447 L 3]} The section from Shallcross Wharf Road to MD 444 is the original alignment of the Kentmore Park Road portion of MD 444. The highway was improved in 1939 and brought into the state highway system as a northward extension of that route in 1942.^{[MD 447 L 4][MD 447 L 5]} After US 213's bypass of Locust Grove was built in 1950 and 1951, the old path of US 213 through Locust Grove—Shallcross Wharf Road between the western end of the bypass and the center of Locust Grove, and Old Locust Grove Road between the center of Locust Grove and the eastern end of the bypass—became part of MD 444, with the eastern section being a spur of the main route.^{[MD 447 L 6][MD 447 L 7]} After MD 444's present course west of Locust Grove was constructed in 1968, Old Locust Grove Road became MD 447 and Shallcross Wharf Road between US 213 and the new MD 447 became MD 449.^{[MD 447 L 6][MD 447 L 8]} MD 447 was resurfaced with bituminous concrete in 1984.^{[MD 447 L 9]} Three years later, MD 447 was transferred from state to county maintenance through a December 1, 1987, road transfer agreement.^{[MD 447 L 1]}
