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. Some time 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 2 and 199 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.

MD 20
edit Maryland Route 20 | |
|---|---|
| Location | Fort Howard–Baltimore |
| Existed | 1927–1998 |
Maryland Route 20 was the designation for North Point Road, which originally ran from the tracks of an interurban near Fort Howard north through Edgemere and Dundalk in southeastern Baltimore County to US 40 in Baltimore. MD 20 was the main highway between Baltimore and Sparrows Point, which was accessed by MD 151 (Sparrows Point Road) from Edgemere.[MD 20 1] The interurban line connected Baltimore with Bay Shore Park, an amusement park that operated between 1906 and 1947 within what is now North Point State Park.[MD 20 1][MD 20 2] As early as 1923 and late as 1928, a ferry connected Bay Shore Park with Rock Hall, thus briefly and indirectly connecting this MD 20 with the extant MD 20 in Kent County.[MD 20 3][MD 20 4][MD 20 5]
The first section of MD 20 was constructed as a concrete road from Sparrows Point Road in Edgemere to Trappe Road at the hamlet of North Point in what is now Dundalk by 1921.[MD 20 6] The concrete road was extended from North Point to Baltimore in 1922 and 1923; those same years, a macadam road was built from Sparrows Point Road to the interurban tracks near Bay Shore Park.[MD 20 3][MD 20 5] MD 20 was widened and resurfaced with bituminous concrete north of Edgemere by 1926.[MD 20 7] By 1934, MD 20 was proposed to be expanded from a width of 18 to 20 feet (5.5 to 6.1 m) to 40 feet (12 m) from Baltimore to MD 151 in Edgemere to serve the Sparrows Point industrial complex. In addition, MD 20 from MD 151 to the interurban near Bay Shore Park was proposed to be widened from 14 feet (4.3 m) to 20 feet (6.1 m).[MD 20 8] The Edgemere portion of MD 20 was bypassed when a new four-lane divided highway—Sparrows Point Boulevard and North Point Boulevard—was completed from Sparrows Point to Wise Avenue in Dundalk in 1940 and 1941.[MD 20 9] Between 1942 and 1944, the remainder of North Point Boulevard was constructed from Wise Avenue to Baltimore as a wartime access project, including a cloverleaf interchange at MD 150.[MD 20 10][MD 20 11] In addition, Erdman Avenue was extended as a four-lane divided highway to connect with North Point Boulevard, bypassing the segment of North Point Road between the boulevard and US 40 in the city of Baltimore.[MD 20 10][MD 20 12]
By 1946, MD 151 was applied to the four-lane divided highway connecting Baltimore with Sparrows Point, and MD 20 was assigned to four mainline segments and a spur of the old North Point Road:[MD 20 12]
- MD 20A was the designation for the 0.51-mile-long (0.82 km) section of North Point Road from the ramp from southbound MD 151 to westbound MD 150 northwest to a dead end at the Canton Railroad near the Baltimore city limit.[MD 20 13]
- MD 20B was the designation for the 2.72-mile-long (4.38 km) section of North Point Road from MD 151 and Cove Road in Dundalk northwest to a right-in/right-out interchange with eastbound MD 150 at the MD 150–MD 151 cloverleaf.[MD 20 13]
- MD 20C was the designation for the 1.30-mile-long (2.09 km) section of North Point Road from MD 151 near Wise Avenue north to MD 151 near Cove Road in Dundalk.[MD 20 13]
- MD 20D was the designation for the 2.53-mile-long (4.07 km) section of North Point Road from the former interurban track intersection at Penwood Avenue near Fort Howard north to MD 151 north of Edgemere.[MD 20 13][MD 20 14] The portion of MD 20 from near Fort Howard to Sparrows Point Road in Edgemere was resurfaced with bituminous concrete in 1969.[MD 20 15]
- MD 20E was an unnamed 0.04-mile-long (0.064 km) spur from MD 20C to a dead end near MD 20C's northern end near Cove Road.[MD 20 13]
The 1.77-mile-long (2.85 km) portion of MD 20D from near Fort Howard to Sparrows Point Road in Edgemere, then MD 718, was transferred from state to county maintenance through a December 12, 1985, road transfer agreement.[MD 20 14] The remainder of MD 20D and all of MD 20A, MD 20B, MD 20C, and MD 20E were transferred to Baltimore County control through an October 1, 1998, road transfer agreement.[MD 20 13]
One segment of MD 20 was constructed later and was not part of North Point Road. MD 20F was an unnamed 0.52-mile-long (0.84 km) connector from southbound MD 151 to MD 20D.[MD 20 16] The highway began as a loop ramp from southbound MD 151, crossed east over both directions of MD 151, and ended at MD 20D.[MD 20 16][MD 20 17] What became MD 20F was constructed as one of several ramps built to connect MD 151 and MD 20 with the new Bethlehem Boulevard in 1957 and 1958.[MD 20 15][MD 20 17][MD 20 18] However, the road did not receive the MD 20F designation until 1976.[MD 20 19][MD 20 20] MD 20F was replaced by an eastward extension of newly designated MD 158 (Bethlehem Boulevard) when Bethlehem Boulevard was transferred from Bethlehem Steel control to state maintenance through an October 17, 1989, road transfer agreement.[MD 20 21] Former MD 20F was destroyed by the reconstruction of I-695 and its junction with MD 151 and MD 158 completed in 1999.[MD 20 22]
