Big rigs banned from Big Dig bridge

| Friday, September 05, 2008

The Federal Highway Administration has asked the state of Massachusetts to restrict heavy trucks from using a section of a connector bridge on Boston’s ill-fated Big Dig project because of a crack that was found on a concrete support earlier this year.

Trucks weighing more than 40 tons will be required to stay off of the Leverett Connector Bridge until repairs to the crack can be completed.

The Boston Globe reported that the Federal Highway Administration sent a letter on Aug. 21 to the state, requesting that the detour be made.

However, the state did not close the bridge to trucks until Wednesday, Sept. 3. State officials told the Globe that they did not receive the letter until Wednesday afternoon and immediately ordered the restrictions.

The crack was discovered during a review of the project following the collapse of the ceiling in one of the tunnels that killed a motorist in July of 2006. The review was completed earlier this year.

Repairs to the crack are expected to be finished by no later than Nov. 1.
