Description: The Sumner Tunnel, located in Massachusetts, is a critical transportation artery that connects downtown Boston to East Boston and Logan International Airport. Opened in 1934, it was the first traffic tunnel in the state and one of the earliest in the United States. The tunnel spans approximately 1.6 miles and runs beneath Boston Harbor, facilitating the movement of thousands of vehicles daily. It operates in conjunction with the parallel Ted Williams Tunnel and the Callahan Tunnel, which together help manage the heavy traffic flow in and out of the city. Over the years, the Sumner Tunnel has undergone various upgrades and maintenance efforts to ensure safety and efficiency, reflecting its enduring importance to Boston's infrastructure and economy.
