in the southern portion of Aberdeen was removed in 1950; MD 159 was extended north to MD 7's new eastern terminus and the remainder of Old Philadelphia Road became the responsibility of Harford County and Aberdeen. MD 7 between MD 213 and South Street in Elkton became one-way eastbound in 2001 and municipally maintained in 2003. The western terminus of that section of MD 7 was truncated at MD 213 in 2010, resulting in the portion of Main Street from a dead end at the Amtrak Northeast Corridor to MD 213 also becoming the responsibility of Elkton. In 2012, the MD 7 designation was removed from the portion of municipally-maintained roadway between MD 213 and South Street. In 2018, a roundabout was constructed at Seven Trails Drive.
