Tobin Bridge & Chelsea local traffic advisories through Nov. 30

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.

Route 1 Lane Shifts

  • Roadway configuration changes on Route 1 northbound and southbound travel lanes will take place overnight on Saturday, 11/23 and Sunday, 11/24, weather permitting.
  • Beginning Monday, 11/25, the new workzones will begin in the left lanes on Route 1 northbound and southbound.
  • Exact dates of lane shifts may adjust if needed.
  • Overnight work will begin one hour after the completion of events at TD Garden.
  • Drivers should take care to pay attention to all signage and move carefully through the workzones. Police details, lane markings, temporary barriers, traffic cones, signage, and other tools will be used to control traffic and create safe work zones.

Traffic Impacts

  • Route 1 Northbound: Approaching the Tobin Bridge from Boston, the workzone begins in the left lane and continues in the center lane. 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.).

  • Fourth Street Off-ramp: The Fourth Street off-ramp will remain closed for approximately 1 more month. Northbound traffic headed to Chelsea must be in the right lane when crossing the bridge to access the Beacon Street off-ramp. After Beacon Street, the next opportunity to exit Route 1 Northbound will be at Webster Avenue.
