Silver Line Gateway

About This Project

The Silver Line Gateway Project will provide new, dedicated bus rapid transit (BRT) service connecting Chelsea and East Boston (via the Blue Line’s Airport Station) with the Red Line’s South Station and Seaport District in Boston. Four new BRT Stations will be located at Eastern Avenue, Box District, Bellingham Square, and Chelsea. The preferred alternative was selected by MassDOT based on public input and due to its fast travel times and high potential ridership.

As part of the project, the Chelsea Commuter Rail Station will be relocated to create a modern and fully accessible station. MassDOT is also coordinating with the City of Chelsea and the Executive Office of Energy and Environmental Affairs to develop the Chelsea Greenway, a new shared-use path. To learn more, visit the Project Overview page.

MassDOT continues to welcome your ideas and participation in this process while the project is in construction. Please sign up for email alerts and participate in community meetings. Interpreters will be available at community meetings and project information will be posted on this website.

Traffic Management

Conversion of Arlington Street and Sixth Street to One-Way

Phase 1 of the Silver Line Gateway Project includes construction of a dedicated busway extending from Everett Avenue to Eastern Avenue. The busway will require changes to intersections at Everett Avenue, Spruce Street, Eastern Avenue and Arlington Street/Sixth Street.

To reduce potential conflicts of turning movements within the 6-legged intersection of Arlington Street, Sixth Street and the Busway, both Arlington Street north of the intersection and Sixth Street east of the intersection will be converted to one-way:

  • Arlington Street will be one-way from Sixth Street to Heard Street
  • Sixth Street will be one-way from Arlington Street to Washington Avenue

The one-way conversion on Arlington Street and Sixth Street will occur at 7:00 AM on Tuesday, August 23. View the One-Way Circulation Map in English or Map in Spanish for details.

Washington Avenue Bridge Closure and Detours

Phase 1 of the Silver Line Gateway Project includes a full replacement of the Washington Avenue Bridge, which requires closing the bridge during certain stages of construction. The Washington Avenue Bridge was closed to vehicles in late May 2015, but it will remain open to pedestrians throughout construction. The bridge is scheduled to reopen to one-way traffic by spring 2016. Completion is scheduled by the end of 2016. During the closure, traffic detours are in place directing vehicles around the work zones via Cary Avenue and Broadway. To view the detour routes, please review the Map in English or the Map in Spanish. For more information about the work, please review the Notice in English or the Notice in Spanish.

For additional information about upcoming construction phases and project design, view the Design & Construction page.
