Maryland Route 185 - History

History

MD 185 was constructed and designated on two different segments of the current state highway at different times. The first section to be built was between Chevy Chase and Kensington as an extension of Connecticut Avenue into Montgomery County, which was designated MD 193. The section between Bradley Lane and Kensington was paved by 1927. The segment south of Bradley Lane was paved as a county road by 1930. By 1936, the segment of Connecticut Avenue south of Bradley Lane had come under state control. The grade crossing of the railroad tracks in Kensington was eliminated by the construction of a bypass and bridge in 1936 as well. The section of MD 193 south of MD 410 was marked as an alternate route of US 240 by 1946, a designation it retained until the 1960s. The segment from the D.C. line to north of MD 410 in Chevy Chase was expanded to a multi-lane divided highway in 1950. The remainder of the route to Kensington was expanded to a divided highway between 1957 and 1960.

The section of highway between Kensington and Aspen Hill was built on a new alignment as a four-lane divided highway in stages in the 1960s and given the designation of MD 185. The highway was completed from Kensington to MD 586 in 1963. The remaining section north to Aspen Hill was completed in 1969. Immediately north of the crossing of Turkey Branch is a bridge that was to be MD 185's overpass of the Washington Outer Beltway. Ramp stubs exist next to the bridge for the partial cloverleaf interchange with this cancelled freeway. By 1980, the MD 185 designation was extended south from Kensington south to the D.C. line. The state highway was expanded to six lanes to Beach Drive in 1986 and through Kensington in 1991.
