Sumner Tunnel

Built in the 1930s, the Sumner Tunnel (Route 1A South) is the first traffic tunnel in Massachusetts and takes vehicles from Logan Airport to Boston/I-93. Now, after nearly a century of service, it’s time for an upgrade.

From July 5 to August 5, the tunnel will be fully closed to traffic. The tunnel will close at 12:01 a.m. on Friday July 5 and reopen by 5 a.m. on Monday August 5.
