Southwest Corridor Park is a 4.1-mile-long (6.6 km) linear urban park in Boston, Massachusetts, part of the Metropolitan Park System of Greater Boston and managed by the Massachusetts Department of Conservation and Recreation. It extends from the South End and Back Bay neighborhoods through Northeastern University's campus to the Forest Hills section of Jamaica Plain in what was originally planned to be the alignment for Interstate 95 to Boston. It follows the routes of regional Amtrak and Commuter Rail lines and the Massachusetts Bay Transportation Authority Orange Line rapid transit rail line, from its Back Bay Station to its terminus at the Forest Hills Station. It features tennis courts, basketball courts, playgrounds, and walking, jogging, and biking paths.
