What is the SL3?

Silver Line 3 Chelsea (SL3) service began on April 21, 2018.

For the cost of a standard subway fare, the SL3 provides service to Chelsea, East Boston, Logan Airport, the Seaport District, and South Station.

The larger Silver Line buses travel in bus-only lanes in Chelsea to avoid traffic—and you don't need to transfer to another line or mode of transit to get to Boston.


Who is the SL3 for?

Three Chelsea residents

The SL3 serves riders who need to go to Chelsea, East Boston, Logan Airport, the Seaport District, or South Station.

The SL3 may offer faster service if you:

  • Take MBTA bus routes 111, 112, 114, 116, or 117: The SL3 offers fewer stops and transfers along these key bus routes, and it travels in an exclusive bus lane in Chelsea to avoid traffic.
  • Transfer from the Blue Line to get to South Station or the Seaport: The SL3 offers direct service to both.
  • Take taxis or rideshares to the airport: The SL3 stops at Airport Station on the Blue Line for a fraction of the cost of a taxi or rideshare.
  • Drive to Boston: Taking public transit saves you money on tolls, gas, and parking. In addition, the SL3 travels in an exclusive bus lane in Chelsea to avoid traffic.

Where does the SL3 stop?

The SL3 stops at 4 new Silver Line stations in Chelsea and 5 existing Silver Line stations in Boston.

    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?
