Maryland Route 458 (MD 458) is a state highway in the U.S. state of Maryland. Known as Silver Hill Road, the highway runs 3.12 miles (5.02 km) from MD 5 in Silver Hill north to Walker Mill Road in District Heights. MD 458 is a four- to six-lane divided highway that connects the inner suburbs of Hillcrest Heights, Silver Hill, Suitland, and District Heights in southern Prince George's County. The highway is a part of the National Highway System between MD 5 and MD 4 as an intermodal connector between those highways and the Suitland station of the Washington Metro.[2] MD 458 was originally constructed in the early 1930s between the original alignments of MD 5 and MD 4. The route was relocated in District Heights in 1960 and widened to a divided highway in the mid-1960s. MD 458 was extended to its present southern and northern termini in the late 1960s and mid-1980s, respectively.

Route description[edit]

MD 458 begins at an intersection with MD 5 (Branch Avenue) in Silver Hill. The west leg of the intersection is Iverson Street, which passes under the Iverson Mall and through Hillcrest Heights. MD 458 heads east as a four-lane divided highway and intersects MD 414, which heads south as St. Barnabas Road and north as Old Silver Hill Road. The highway expands to six lanes east of MD 414 and passes a Smithsonian Institution Libraries support center. MD 458 enters Suitland at its partial cloverleaf interchange with the Suitland Parkway. Just beyond the parkway, the highway passes the Suitland station on the Washington Metro's Green Line. MD 458 continues past the Suitland Federal Center, whose main tenant is the U.S. Census Bureau, and intersects Suitland Road, which heads northwest as MD 218 in the center of Suitland. The highway passes Suitland High School before its intersection with MD 4 (Pennsylvania Avenue). Just east of MD 4, unsigned MD 972 splits east along Old Silver Hill Road toward the center of District Heights. MD 458 passes along the edge of the town and intersects Marlboro Pike before reaching its northern terminus at Walker Mill Road. The intersection is a T-intersection with Walker Mill Road turning from southeast to northeast at the junction; this portion of Walker Mill Road is unsigned MD 458A.[1][3]


MD 458 was constructed as a concrete road in two sections—from MD 5 (now MD 414) in Silver Hill to MD 218 in Suitland, and from MD 218 to MD 4 (now Marlboro Pike) in District Heights—between 1930 and 1933.[4][5] The whole highway was widened with the addition of a pair of 3.5-foot-wide (1.1 m) bituminous shoulders between 1940 and 1942.[6] MD 458's interchange with the Suitland Parkway was built in its modern configuration when the parkway was constructed through Suitland in 1943.[7][8] The first divided highway portion of MD 458 was created in 1960 when the highway was relocated from just south of the just-completed present alignment of MD 4 north to the old alignment of MD 4 in District Heights.[9] Marlboro Pike became MD 4 Business, which was removed in 1970; Old Silver Hill Road became MD 972A.[9][10] The divided highway was extended west from MD 4 to MD 414 in 1965.[7][11] MD 458 was constructed as a divided highway to its present terminus at MD 5 in 1967; Old Silver Hill Road became an extension of MD 414.[12] The highway was constructed as a divided highway from Marlboro Pike north to its present terminus with Walker Mill Road in 1985.[13]
