The East Street Bridge that carries the Massachusetts Bay Transportation Authority (MBTA) Franklin Commuter Rail Line will undergo weekend work Oct. 19 and Nov. 9, MBTA has announced.
Weekend bus service will be available to customers along the Franklin Line during work on the East Street Bridge Rehabilitation Project, officials said. Regular service is set to resume Oct. 22 and Nov. 12, respectively.
Built in 1911, the East Street Bridge is based in Westwood, Mass. Construction plans are focused on extending the bridge’s useful life. Work on the existing bridge has been ongoing since March 2018 and has entailed the installation of deep foundations behind the existing abutments, utility relocation and track reconstruction.
New precast concrete abutment caps, precast concrete approach slabs and two steel superstructures will be installed throughout two separate weekends using accelerated bridge construction techniques, MBTA said.
During the October weekend construction work, abutment caps and approach slabs will be lifted into place and attached to previously installed drilled shafts.
During the November weekend construction work, the bridge superstructure will be moved from the MassDOT Yard at Grafton Avenue and travel along Strafford Road to East Street. It will then be put into place and attached to the new bridge abutments.
