Maryland Route 650

Maryland Route 650 (MD 650) is a state highway in the U.S. state of Maryland. Known as New Hampshire Avenue for most of its length, the state highway runs from Eastern Avenue at the Washington, D.C. border north to MD 108 in Etchison. MD 650 serves as a major north-south commuter route in southwestern Prince George's County and eastern Montgomery County, connecting the District of Columbia with the residential suburbs of Takoma Park, Langley Park, Maryland, Adelphi, Hillandale, White Oak, and Colesville. By contrast, the part of MD 650 north of Spencerville is a quiet rural road connecting several small communities along the northeastern fringe of Montgomery County.
