Charles Street, known for most of its existence as
Maryland Route 139, runs through
Baltimore City and through the
Towson area of
Baltimore County. On the north end it terminates at an intersection with
Bellona Avenue near
Interstate 695 and at the south end it terminates in
Federal Hill in Baltimore. Charles Street is one of the major routes through the city of Baltimore, and is a major public transportation corridor. For the one-way portions of Charles Street, the street is functionally complemented by the parallel
St. Paul Street (including St. Paul Place and Preston Gardens),
Maryland Avenue,
Cathedral Street, and
Liberty Street.
