What is the SL3?

If you live in East Boston and Chelsea, there’s a new way to get where you need to go: Silver Line 3 Chelsea (SL3)

The SL3 travels through Chelsea and East Boston to Logan Airport, the Seaport District, and South Station. It makes connections to many area bus routes (including the 111, 112, 114, 116, and 117), as well the Blue Line, Red Line, and Commuter Rail. 

Silver Line buses are larger than regular MBTA buses, with room for more passengers as well as luggage and strollers. And don’t worry about getting stuck in traffic--the SL3 travels in dedicated bus-only lanes through Chelsea.

    What are the buses like?

    SL3 rapid transit buses are roomier and offer a smoother ride than other MBTA buses. Like other Silver Line buses, they include plenty of space for luggage if you're going to the airport.

    All Silver Line buses are accessible to people with disabilities.


    How does the Chelsea Street Bridge impact the SL3?
