Silver Line 3 Chelsea (SL3)
Timeline: 2015 – 2018
Status: Complete
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.
Building a Better T
As part of our $9.6 billion, 5-year capital investment plan, we're renovating stations, modernizing fare collection systems, upgrading services for our buses, subways, and ferries, and improving the accessibility of the entire system.
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
- Bellingham Sq Station at Arlington and 6th St
- Box District Station at Gerrish Ave and Highland St
- Eastern Ave Station at Eastern and Central Ave
- Airport Station, connect to Blue Line and Massport Shuttle
- Silver Line Way, Seaport
- World Trade Center Station, Seaport
- Courthouse Station, Seaport
- South Station, connect to Red Line and Commuter Rail
Where does the SL3 connect to other bus routes?
You can make quick, easy connections to bus routes 111, 112, 114, 116, and 117 at the new Silver Line stations in Chelsea.
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?
We alert SL3 drivers before the bridge goes up and provide alternate routes based on real-time traffic information. Those alerts will be available to the general public soon.
