Transportation Projects in Somerville

Here’s a quick overview of transportation projects, some planned, some potential, all useful! Read the summaries below the map, and click the map to enlarge.

Green Line Extension (GLX)
Phase 1 of the GLX project for six new open-air stations and the relocated Lechmere station is nearly complete and scheduled to be operational in late 2022. The ADA-compliant stations have canopies and benches, bike storage, and feature an interim solution toward the MBTA’s forthcoming new fare payment system. Ridership at the seven stations is projected to be approximately 45,000 – 49,000 riders per day. Phase 2 of GLX, as yet unscheduled and in need of an updated environmental review, will extend the route from the Phase 1 terminus at Medford/Tufts station down the commuter rail tracks along Boston Ave. to the current U-Haul building, which will be the site of a new terminus at Route 16.

Community Path Extension
The full multi-use Community Path extension will run mostly alongside the west/south side of the Medford branch of GLX from Magoun Square station to Lechmere station, connecting four stations, branching into a dedicated flyover structure over the Fitchburg Commuter Rail tracks, and terminating at street level at Lechmere Station and Cambridge Crossing. This fully off-road Path extension will connect the Minuteman and Charles River path networks, linking a network of approximately 48 miles of continuous bike/pedestrian path, connecting 11 Boston area cities and towns, and creating the eastern six miles of the 104-mile Mass Central Rail Trail. The Path extension is expected to be complete in fall 2022, shortly after the opening of the Medford branch GLX stations. Learn more.

Mystic River Ped/Bike Bridge
The project to build a pedestrian/bike bridge across the Mystic River, led by DCR in partnership with MassDOT, would connect Somerville and Charlestown at Draw Seven Park with Everett at the site of the Encore casino. The $32 million bridge, would connect the casino area directly to the Assembly Orange Line station. In Everett, the bridge would also be a key Boston connection for bike paths to Lynn and the North Shore. The project is in 75 % design phase with funding in hand to complete the design and permitting in 2022. The state has committed capital funding to build the bridge by 2026. Learn more.

McGrath Boulevard
From 2015 to 2018, MassDOT led a conceptual design process with the Somerville community and other regional stakeholders for the removal of the McCarthy Overpass on Route 28 (McGrath Highway over Washington St.) and turn McGrath into a street-level multi-modal boulevard. The goal is to reconnect Union Square with East Somerville and Inner Belt and make the route safer and more accessible for pedestrians, cyclists, and motorists. The current concept provides a multi-modal boulevard with bike/ped features and a primarily 4-lane vehicle cross section. MassDOT is now advancing the project to the 25% design phase. Public engagement will be part of this phase, once the design is underway. Federal funding for the project is programmed in the Boston Metropolitan Planning Organization’s (MPO’s) 2023-2027 Transportation Improvement Plan (TIP). Learn more.

Silver Line Extension (SLX)
The MBTA SLX project would extend Silver Line bus rapid transit service to and from Everett and Chelsea, and include Somerville and Cambridge. Three of the six route alternatives being analyzed extend the existing SL3 line, and three are of a new proposed SLX line between Everett, Sullivan Square, and either Kendall Square or downtown Boston. One route connects Sullivan and Kendall Squares through Somerville via McGrath Boulevard. Learn more.

Innerbelt Multi-Use Path
The proposed multi-use path would link the Assembly and Sullivan Orange Line stations, the Innerbelt neighborhood, and the new East Somerville GLX station at Washington St. In addition to providing off-street transit connections, this path would provide off-street connections between the Charles River (via the Community Path extension) and Mystic River path networks.
