Sumner Tunnel restoration project changes closure schedule to reduce impact on travelers this summer

BOSTON — The Sumner Tunnel restoration project has changed its full closure schedule to reduce the impact on travelers this summer.

The $135-million project to restore the Sumner Tunnel in Boston began in June 2022.

The work is being done in Phases. Phase one includes 36 weekend closures.

Phase 2 was originally supposed to include the full closure of the tunnel from May 2023 to September 2023.

Now, full tunnel closure will no longer occur May-September this year. Instead, full closure will happen from July 5 -August 31.

The second full closure will happen from July to August 2024.

“We are pleased to be announcing a shorter closure of the Sumner Tunnel to traffic this summer, basically half as long this summer as previously planned,” said Highway Administrator Jonathan Gulliver. “Since launching the Sumner Tunnel Restoration Project last year, we have been working closely with our contractor to identify every opportunity to reduce traffic impacts.  Breaking up the full closure for only eight and a half weeks this summer rather than four months significantly benefits regional travelers, local businesses, and area residents.”
