"Massive Traffic Delays Expected as Sumner Tunnel Shuts Down for 2 Months"

State transportation officials are warning residents of severe congestion and multi-mile backups during the two-month closure of the Sumner Tunnel in Massachusetts. They are urging people to use public transit and offering incentives such as free subway and ferry services, discounted bus fares, and priority access at Logan Airport. The closure, starting on July 5, is part of a $160 million infrastructure investment to upgrade the tunnel, which was built in the 1930s. The project will also include another two-month closure next summer with weekend shutdowns in between.
