Big Dig ceiling collapse

Traffic crawls over a closed Fort Point Channel Tunnel entrance in Boston during rush hour on July 11, 2006, a day after the collapse.

The Big Dig ceiling collapse occurred on July 10, 2006, when a concrete ceiling panel and debris weighing 26 short tons (52,000 lb; 24,000 kg) and measuring 20 by 40 feet (6.1 by 12.2 m) fell in Boston's Fort Point Channel Tunnel (which connects to the Ted Williams Tunnel).[1] The panel fell on a car traveling on the two-lane ramp connecting northbound I-93 to eastbound I-90 in South Boston, killing a passenger and injuring the driver. Investigation and repair of the collapse caused a section of the Big Dig project to be closed for almost a full year, causing chronic traffic backups.
