GLX and the Green Line Transformation (GLT) Lechmere Viaduct Rehabilitation Project are working concurrently to rebuild and restore historic structure for enhanced future service

Bus Replacement Service – Lechmere to North Station

GLX improvements will require Green Line service between Lechmere and North Stations to be interrupted for approximately one year beginning May 24, to remove, rebuild, and relocate a section of viaduct and construct a new Lechmere Station.

Structural upgrades will be completed by two separate MBTA entities—GLX and the Lechmere Viaduct Rehabilitation Project—working in close coordination with one another.  Ultimately, the two projects will allow more trains to pass over the elevated structure providing both new branches of GLX with high capacity service.

• During the closure, Green Line service between Lechmere Station and North Station will be provided via replacement bus service.
• Existing commuter bus routes (69, 80, 87, & 88) will continue regular service to their usual terminus at the existing bus garage at Lechmere Station during Green Line service outage.
• Pavement markings on Charles River Dam Road will be temporarily reconfigured during the track outage to include all-day dedicated bus lanes in both directions.
• The replacement bus service plan, which preserves the existing bicycle and pedestrian accommodations, also maintains two vehicular travel lanes on Charles River Dam Road, and one left-turn lane in the Cambridge-bound direction.
• When this segment of viaduct / station work is complete, Green Line service will be restored from North Station to the new Lechmere Station.
• Final completion of the GLX project, including two additional, new Green Line branches—to Union Square in Somerville and to Medford / Tufts Station in Medford—is anticipated by December 2021.
