Construction Look-Ahead: August 9 – 22 

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 Traffic Impacts

Route 1 Northbound: Approaching the Tobin Bridge from Boston, the work zone begins in the left lane. 2 of 3 travel lanes will be open during daytime hours (5 a.m.–10 p.m.) 

Route 1 Southbound: Approaching the Chelsea Curves from the North Shore, the work zone begins in the left lane before the Carter Street off-ramp. 2 of 3 travel lanes will be open during daytime hours (5 a.m.–10 p.m.)

Lane Shift: During the overnight hours on Friday, August 14, roadway configuration changes and southbound (towards Boston) lane shifts will take place in the Chelsea Viaduct portion of the combined Tobin Bridge/Chelsea Curves Rehabilitation project.  Work will begin after 9 p.m. and finish before 5 a.m. the following day.  This operation is weather dependent.  If weather conditions are not right on the 14, the operation will take place overnight on August 17.

•Once the shift is complete, southbound traffic will be split into two lanes with the work zone between them from approximately the top of the Carter Street off-ramp, adjacent to Chelsea High School, to 4th Street, adjacent to the 4th Street northbound off-ramp and the Congregation Agudas Shalom synagogue.

Detour Between Carter and Everett Ramp: There will be a detour between the Carter Street and Everett Street South Bound lanes on Thursday, 8/13 and Friday 8/14 during the nighttime (11 p.m. to 4 a.m.). The detour will allow for the reconfiguration of the temporary barrier from Stage 3 to Stage 4.
