The Commonwealth Avenue bridge’s expected lane closures for construction have been pushed back a year due to design errors made by the company selected to rebuild portions of the bridge, according to a statement from the Massachusetts Department of Transportation.
In 2015, Walsh Construction Co. was awarded the contract with a bid of $81.8 million to renovate the bridge. The construction company’s initial plan indicated that the significant closures the project required would occur in the summer of 2016 and the summer of 2017.
Now, according to MassDOT, the closures are planned for several weeks during the summer of 2017 and 2018.
The closures will still affect the MBTA’s Green Line, commuter rail, traffic on Comm. Ave., and the Mass. Pike, according to MassDOT.
By no longer meeting the original deadline, Walsh Construction forfeits the $7.2 million incentive for completing the project on schedule. Representatives from the construction company said the steel girders for the project had to be redesigned, which resulted in the delay.
“In conjunction with MassDOT and our designer, we have resolved these issues and look forward to successfully completing the first phase of the project in the summer of 2017,’’ representatives from the construction company wrote in MassDOT’s statement.
