The Massachusetts Department of Transportation (MassDOT) will begin demolishing the toll plaza at the Sumner Tunnel in East Boston on Friday night.
Work will continue during overnight off-peak closures and continue during overnight, off-peak closures of the Sumner Tunnel this weekend through 5 a.m., on Monday, May 8, in order to allow for the removal of the existing toll plaza structure and canopy.
During the overnight closures of the Sumner Tunnel beginning Friday evening, all traffic will be detoured through the Ted Williams Tunnel, and the full closure hours will be as follows:
• From 9 p.m. on Friday, May 5, through 9 a.m. on Saturday, May 6
• From 9 p.m. on Saturday, May 6, through 9 a.m. on Sunday, May 7
• From 9 p.m. on Sunday, May 7, through 5 a.m. on Monday, May 8
Additionally, on Saturday, May 6, from 9 a.m. through 9 p.m., demolition-related work will necessitate the closure of the Porter Street entrance to the Sumner Tunnel.
Vehicles accessing the tunnel during this time should follow the detour route along Bennington Street, Marion Street, Chelsea Street and Visconti Road. MassDOT expects to have the tunnel open for traffic in time for the Monday morning commute.
The full scope of work for this project consists of removing the existing toll plaza structure, removing roadway materials, milling and paving, and preparing the roadway for after plaza demolition traffic usage.
Work-related logistical activities at the Sumner Tunnel began last month, including marking utilities and installing temporary signage. All construction work is scheduled to be completed by the end of 2017.
Throughout the Sumner Tunnel project, two lanes of travel will be maintained and a temporary traffic signal will control local street access into the Tunnel. In order to allow crews to safely and effectively conduct construction operations, there will be temporary off-peak lane closures at various points throughout the project.
