The original structurally deficient bridge carrying Morton Street over the MBTA commuter rail tracks closed on Friday, August 8 for final demolition and installation of the new bridge. The new bridge opened to traffic just nine days later, at approximately 3:00am on Sunday, August 17.
MassDOT’s Highway Division used Accelerated Bridge Construction methods to minimize impact on the neighborhood and traffic. Crews assembled a new single span bridge structure adjacent to the crossing, and then rolled the structure into place using “heavy lift” equipment.
“The innovative “heavy lift” accelerated process is once again a proven success in delivering new infrastructure with only a short term disruption for motorists and commuters,” said MassDOT Secretary and CEO Richard A. Davey. “I congratulate the team for completing the work ahead of their aggressive schedule.”
MassDOT also used Accelerated Bridge Construction and “heavy lift” methods in 2012 to replace the River Street Bridge crossing over the MBTA and CSX railroad tracks in Hyde Park, in addition to previous “heavy lift” bridge projects in Phillipston and Wellesley. During the work, heavy-lifting machines called Self-Propelled Modular Transporters lift the new superstructure from its supports to its final destination and lower it into position.
