Maryland Route 851
Maryland Route 851 (MD 851) is a state highway in the U.S. state of Maryland. The state highway runs as a north–south highway between junctions with MD 32 in Sykesville. MD 851 is the old alignment of MD 32 through Sykesville, which was paved by 1910. The state highway was designated when the MD 32 bypass of Sykesville opened in 1963. MD 851 was relocated at its northern end in 2006. Route description MD 851 begins at an intersection with MD 32 (Sykesville Road) in Howard County south of Sykesville. The state highway heads north as two-lane undivided West Friendship Road along the edge of Hugg-Thomas Wildlife Management Area into the narrow valley of the Patapsco River. MD 851 traverses the river and crosses CSX's Old Main Line Subdivision railroad line at-grade as the highway enters the town of Sykesville in Carroll County, where the highway's name changes to Main Street. The state highway passes through the Sykesville Historic District. At the northern end of the town center, MD 851 turns northeast onto Springfield Avenue while Spout Hill Road continues straight toward Springfield Presbyterian Church. The state highway passes Millard Cooper Park, a park and ride lot, and Third Avenue
