History
The first section of River Road to be paved was from the District of Columbia boundary west to Wilson Lane at the hamlet of Cohasset. Montgomery County applied for state aid for the road by 1910; it was built as a 10-foot-wide (3.0 m) macadam road by 1915.[5][6] A second section of macadam road was built from Bradley Lane to a point just west of Potomac by 1923.[7] The western section was extended as a concrete road from Potomac to near Piney Meetinghouse Road in 1925 and 1926.[8][9] A third segment of MD 190 was built as a concrete road from Cabin John Creek to Booze Creek in 1928.[10] The original extent of the state highway was finished when the gaps in the highway between Bradley Lane and Wilson Lane were filled with macadam roadway by 1930.[11] MD 190 was extended west from Piney Meetinghouse Road to Travilah Road, which was then MD 421, in 1950.[12] River Road from MD 421 to MD 112 was completely reconstructed as a federal aid project for Montgomery County between 1954 and 1956.[13][14] This improved road was brought into the state system as the westernmost portion of MD 190 in 1974.[15] MD 190 was expanded to a four-lane divided highway from just west of the I-495 interchange east to the Georgetown Branch railroad crossing in 1963, the same year the highway's interchange with I-495 opened.[16] The Capital Crescent Trail's bridge across MD 190 was completed in 1996.[17]
