Tobin Bridge & Chelsea local traffic advisories through Sept. 21

This is a brief overview of construction operations and traffic impacts for the Tobin Bridge/Chelsea Curves Rehabilitation Project. MassDOT will provide additional notices as needed for high-impact work, temporary ramp and street closures, and changes to traffic configurations beyond those described below.

Traffic Impacts

  • Route 1 Northbound: Approaching the Tobin Bridge from Boston, the workzone begins in the center lane. Local traffic headed to Chelsea must be in the right lane to access the Beacon Street off-ramp. After Beacon Street, the next opportunity to exit Route 1 Northbound will be at Webster Avenue. 2 of 3 travel lanes will be open during daytime hours (5 a.m. – 10 p.m.) and at least 1 travel lane will be open during overnight hours (10 p.m. – 5 a.m.).
  • Route 1 Southbound: Approaching the Chelsea Curves from the North Shore, the workzone begins in the right lane at the Carter Street off-ramp. 2 of 3 travel lanes will be open during daytime hours (5 a.m. – 10 p.m.) and at least 1 travel lane will be open during overnight hours (10 p.m. – 5 a.m.).
  • Ramps: The Fourth Street off-ramp will remain closed for 2-3 months. Overnight on 9/8 after the last MBTA bus, the Beacon Street off-ramp will be closed until 5 a.m.
  • Local Streets: Orange Street under Route 1 will close overnights (7 p.m.–6 a.m.), 9/15 – 9/20. Carter Street lanes will be shifted to allow for a workzone on the westbound side starting 9/9. Traffic will remain two-way and police details will be used to guide travelers.
