Tobin Bridge/Chelsea Curves Rehabilitation Project

Work on the Tobin Bridge/Chelsea Curves Rehabilitation Project began April 1, 2019. It requires closures in both the north and southbound lanes, as well as the on ramps in Chelsea.

This work is expected to result in significant traffic delays. Customers who take the 111, 426, and 428 buses may want to seek alternate routes, especially during peak travel times.
