Silver Line 3 Chelsea (SL3)
Updated on August 7, 2018
Timeline: 2015 – 2018
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 as 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.
Where does the SL3 stop?
The SL3 stops at 4 new Silver Line stations in Chelsea and 5 existing Silver Line stations in Boston:
- Chelsea Station at Everett Ave
