A portion of the ceiling in the tunnel connecting Interstate 93 north to the Ted Williams Tunnel collapsed last night, cascading debris onto a passing car and killing a female passenger, authorities said this morning....
The tunnel system is part of the Big Dig construction project overseen by the Massachusetts Turnpike Authority. State Police said the tunnel was shut down to give engineers time to study the extent of the damage to the ceiling and to the roadway. On its website, the Turnpike Authority said that the I-90 east connector tunnel to the Ted Williams Tunnel is closed and that all traffic was being diverted at Exit 24....
It was not clear this morning whether the latest ceiling collapse was related to water leaks that have plagued the tunnels.
Radio reports this morning indicate that traffic is gridlocked all around the city as a result of the tunnel closure, which is expected to continue into tomorrow; if you are traveling into Boston (especially to Logan Airport), you would be well advised to take public transportation if at all possible. The T has added extra Blue Line and Silver Line service to the airport.
Turnpike Chairman Matt Amorello is being interviewed now on WBUR. He's talking about the investigation into what happened (still seems fairly unclear), and the repair work that will have to be done.
