The Ted Williams Tunnel westbound will be closed weeknights from 11:30 p.m. to 5 a.m. the following morning. One lane of the tunnel will also be closed at 9 p.m. Monday through Friday.
This closure by the Massachusetts Turnpike Authority is scheduled to allow for ongoing work to overhead fans, hanger and signage installation.
All traffic will be detoured to the Sumner Tunnel. Motorists destined for I-90 (Masspike) West and I-93 South should keep left and follow signs for Government Center and then follow detour signs and police direction for I-93 South and I-90 (Masspike) West. All ramp connections from the Sumner Tunnel to I-93 North and Storrow Drive will remain open when the Ted Williams Tunnel is closed.
