These 11 highways are service roads related to and sections of an old alignment of MD 31 between New Windsor and Manchester in Carroll County.

Access between the two highways was cut off in 2008 when a traffic signal was added at the MD 31–Tahoma Farm Road intersection.

MD 852K becomes municipally-maintained just south of where houses start to line the westbound side of the highway.

The state highway climbs to the top of the ridge on which downtown Westminster sits and reaches its eastern terminus at the intersection of Main Street and Uniontown Road on the edge of the Western Maryland College Historic District and the district's namesake, McDaniel College.

MD 852G curves to the northeast and passes through a mix of farmland and scattered residences.

[1][6] MD 31 from New Windsor to Westminster was originally constructed as a 15-foot (4.6 m) wide concrete road between 1919 and 1921.

[7][8] The state highway was widened to 21 feet (6.4 m) with a pair of 3-foot (0.91 m) wide macadam shoulders between 1936 and 1939.

[12] By 1978, the state highway was municipally-maintained on its present stretch, which was named Doyle Avenue.
