MBTA Services in Cambridge

Nearly every part of Cambridge’s 6 square miles is within a short walk of a subway station or bus stop.  Here is a summary of T service in Cambridge

Red Line Subway

There are five Red Line stations in Cambridge (plus a sixth just across the city line in Davis Square, Somerville), each about a mile apart.  The heavy rail subway line run underneath Massachusetts Avenue for most of its length before terminating at Alewife Station near the Arlington town line.  Trains run about 4 minutes apart in the rush hours and 10 minutes apart at all other times.

The Red Line provides fast and direct access to downtown Boston and South Station, where rail connections to the south shore and he eastern seaboard are available.

Green Line Trolley

The northern end of the Green Line Trolley terminates at Lechmere Square in East Cambridge.  North Station, which provides rail service to the north shore and Maine, is two stops away.

MBTA plans to extend the Green Line past Lechmere to Somerville and Medford.  Preliminary work has already begun.  To learn more about the Green Line Extension Project, please click here.
