Canterbury Street Bridge Closure and MBTA Bus Diversions: Boston Tuesday Traffic Update

Commuter Alert: Major Bridge Closure and Transit Adjustments

As of Tuesday, February 17, 2026, commuters in the Greater Boston area should prepare for significant localized delays due to ongoing bridge reconstruction and public transit service changes. While the major weekend shutdowns on the Orange Line have concluded for the moment, several key surface-level disruptions remain in effect for the Tuesday morning and evening rush hours.

Key Roadway Impacts and Bridge Closures

The most significant long-term disruption remains the full closure of the Canterbury Street Bridge to vehicular traffic. Following a recent structural inspection by the Massachusetts Department of Transportation (MassDOT), the bridge is closed until further notice. Drivers are advised to utilize the following detour routes to navigate the Roslindale and Hyde Park areas:

• Primary Detour: Traffic is being rerouted via Hyde Park Avenue, Cummins Highway, Rowe Street, Brown Avenue, and Seymour Street.
• Eastbound Route: Follow Seymour Street to Brown Avenue to Cummins Highway.
• Westbound Route: Utilize Hyde Park Avenue to Cummins Highway and Rowe Street.

Additionally, in Downtown Boston, motorists should notice early parking restrictions appearing on Cambridge Street near City Hall Plaza. These are in preparation for the upcoming Red Bull Snowboarding event scheduled for later this week. Both sides of Cambridge Street from Court Street to New Sudbury Street are affected.

MBTA Service Updates and Bus Diversions

Public transit riders can expect a return to regular rail service on the Orange Line following the successful completion of signal upgrades between Jackson Square and Forest Hills this past weekend. However, several bus and Silver Line adjustments are currently active:

• Silver Line (SL1, SL2, SL3): While currently operating normally, be advised that starting tomorrow evening, February 18, these lines will shift to street-level operation between Silver Line Way and South Station for tunnel maintenance.
• Bus Routes 77 and 96: The outbound stop at Massachusetts Ave @ Wendell St has been moved approximately 100 feet south between 7:00 AM and 4:00 PM due to active construction.
• Route 70: The stop at Green St @ Magazine St remains closed through the end of the month. Riders should use the temporary stop at Western Ave @ Green St.

Commuter Recommendations

Commuters are encouraged to budget an additional 15 to 20 minutes for travel through the Hyde Park and Roslindale corridors due to the Canterbury Street detour. For those using the MBTA, real-time tracking for diverted bus routes may be less accurate; the MBTA Go app remains the most reliable source for immediate arrival data. Pedestrian access across the Canterbury Street Bridge remains open, offering a viable alternative for those traveling locally on foot.
