The Sumner Tunnel — which connects downtown Boston to East Boston and is a key route to Logan Airport — reopened Monday after a month-long closure.
The tunnel closed on July 5 to allow crews to do repair work on its ceiling, roadway, walls, lighting and more. Massachusetts Transportation Secretary Monica Tibbits-Nutt said previously that the work would make the tunnel safer and more climate resilient.
This was the second such closure to happen in the last two years, though last summer’s closure lasted two months instead of one. The closures were part of a $160 million project meant to improve and rehabilitate the nearly century-old tunnel.
