Fort Point Channel Tunnel

The Fort Point Channel Tunnel is a tunnel in Boston, Massachusetts, United States. It carries the Massachusetts Turnpike underneath the Fort Point Channel and South Boston streets.

History

The tunnel was built during 1991–1994 as part of the Big Dig. It was built using a casting basin.
In July 2006, a ceiling tile and associated debris weighing collapsed, causing the death of a passenger in a vehicle in the tunnel and severe injury to the driver. This incident and the resulting inspections and repairs delayed the Big Dig construction project by a year.
