The Fort Point Channel Tunnel is a tunnel in Boston, Massachusetts. It carries the Massachusetts Turnpike (Interstate 90) underneath the Fort Point Channel and South Boston streets.

History

The tunnel was built during 1991–1994 as part of the Big Dig. [1] [2] It was built using a casting basin.

In July 2006, a ceiling tile and associated debris weighing 26 short tons (52,000 lb; 24,000 kg) collapsed, causing the death of a passenger in a vehicle in the tunnel and severe injury to the driver. [3] This incident and the resulting inspections and repairs delayed the Big Dig construction project by a year.
