Sumner Tunnel Shutdown: Tuesday Traffic Test

The Sumner Tunnel in Boston is undergoing a major renovation, resulting in its closure for eight weeks. MassDOT authorities expect Tuesday, Wednesday, and Thursday to have the heaviest traffic during morning and afternoon commutes, providing a more accurate idea of the project's impact. Last week's traffic was light due to the Fourth of July holiday, but as holiday travelers return, traffic is expected to increase. Officials are encouraging commuters to use alternative routes and public transportation, such as the Blue Line, Commuter Rail, and ferries, which are being offered at reduced prices or for free.
