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.
The City of Cambridge and the MBTA are working together on the Better Bus Project
We are working with the MBTA on their Better Bus Project to make buses operate better in Cambridge. The MBTA is seeking your feedback on bus operations. Please take a moment to submit comments to the Better Bus Project on-line survey. In late 2018, the Better Bus Project team will propose changes to bus service based on the research, partnerships, and public feedback. Customers should expect to see service changes and improvements, related to the Better Bus Project, between now and 2020.
The MBTA runs 21 bus lines that serve Cambridge neighborhoods. Here is a listing of the routes by area of the City. Please find a PDF map here displaying the public transit routes in Cambridge. Click on the links to get more information from MBTA for each route.
