Interstate 795 Maryland

North End
South End


Named the Northwest Expressway, Interstate 795 serves Reistertown, Westminster and other suburbs in Baltimore County. The freeway is six lanes wide between Interstate 695 and Owings Mill (Exit 4) and four lanes wide for the remainder of the route to Reistertown. The Maryland Transit Administration (MTA) Metro SubwayLink runs along I-795 between Owings Mill and the Baltimore Beltway between the north and southbound roadways.


AASHTO approved the designation for Interstate 795 from Randallstown northwest to Owings Mill on June 25, 1979. The Northwest Expressway was completed between I-695 and Reisterstown in October 1987.1

Original plans for the Northwest Expressway extended the route southward from I-695 to Wabash Avenue in the city of Baltimore. The proposed corridor followed the Metro SubwayLink line through the Mount Hope and Forest Park neighborhoods. The urban freeway spur was never built and Wabash Avenue was instead constructed as a six-lane surface arterial.
