MassDOT this past weekend successfully completed the latest "Heavy Lift" project as part of the Patrick-Murray Administration's Accelerated Bridge Program to rebuild structurally-deficient bridges across the Commonwealth.
Demolition work on the former River Street Bridge carrying traffic over the MBTA and CSX Railroad in Boston's Hyde Park neighborhood, seen at left, began late on Friday, April 13. MassDOT crews then moved a pre-constructed new bridge superstructure into place using specialized heavy lifting equipment, Self-Propelled Modular Transporters.
The transporters lifted the new superstructure, moved it along the railroad tracks below the bridge, and lowered it into position, below left. Workers paved the approaches to the bridge, and River Street reopened to traffic ahead of the already aggressive weekend schedule at 11:45pm, Monday, April 16.
By using accelerated bridge construction methods on this project, MassDOT avoided more than two years of lane restrictions and reduced the period of night work. MassDOT has successfully used the "heavy lift" technique to replace bridges in Phillipston, Wellesley and Boston.
