Southwest Corridor

From Wikipedia, the free encyclopedia

This page is about the cancelled highway near Boston, Massachusetts. For the future light rail project in Minneapolis, Minnesota, see Southwest Corridor (Minneapolis).

The Southwest Corridor or Southwest Expressway was a project designed to bring an eight-lane highway into the City of Boston from a direction southwesterly of downtown. It was supposed to connect with Interstate 95 at Route 128.

The project started in 1948 with William F. Callahan's Master Highway Plan for Metropolitan Boston, went through several adjustments and then was killed in 1972 by Republican Governor Francis Sargent, following popular pressure. (Gov. Sargent declared a moratorium on all expressway construction within Route 128.) Having been witness to recent housing clearances for the Interstate 93 expressway and Massachusetts Turnpike, as well as similar projects in New York City and other cities, the population of the affected area was largely unwilling to repeat similar costs for another expressway.

The corridor was later recycled into the new route for the MBTA's Orange line and Amtrak's Northeast Corridor with much of the surface area being developed as a 52 acre (210,000 m²) linear park.


The 128–93–95 interchange was partially constructed, leaving a few abandoned ramps north of the interchange and one abandoned bridge (42°12′32″N 71°08′33″W / 42.208876, -71.142483) just west of the two active bridges.
