Latest Innovative “Heavy Lift” Project Installs New Bridge in Nine Days
BOSTON- Tuesday, August 19, 2014- The Massachusetts Department of Transportation (MassDOT) today announced the successful opening of the new Morton Street Bridge in Mattapan more than a full day ahead of the already accelerated schedule.
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.”
“I want to thank MassDOT for their efficient and effective work on the Morton Street Bridge, a critical connector for the Dorchester and Mattapan communities,” said Mayor Martin J.Walsh. “I’m pleased the project was done ahead of schedule, limiting the time drivers and the surrounding community were inconvenienced, and getting this necessary infrastructure work done.”
“The Morton Street Bridge is open! I thank the Mattapan community for their patience and collaboration during this process,” said Senator Linda Dorcena Forry. “I also thank MassDOT and their contractors for placing the new bridge ahead of schedule. What could have been a two year closure was completed in just nine days. MassDOT continues to show they listen and are invested in our communities.”
“It is not easy to have such a heavily used bridge shut down for any length of time.” State Representative Dan Cullinane said. “But, closing the bridge and finishing the project in just nine days was a far better alternative than keeping the bridge open with traffic reduced to one lane for three years. The residents and businesses in the surrounding community deserve a tremendous amount of credit for making this project a success – not just for their patience – but for their participation throughout the planning process.”
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.
