Constructed under MassDOT's Accelerated Bridge Program, the $54-million Neponset River Bridge rehabilitation project was delivered by the project team in March, five months ahead of schedule. The project was split into two phases to better respond to traffic concerns. The 2,300-ft-long bridge carries more than 70,000 vehicles each day between Quincy and Boston.
The $20-million Phase 1 substructure rehabilitation contract, which started in August 2006, included complete reconstruction of deteriorated hammerhead pier caps and a seismic retrofit. The $34-million Phase 2 provided roadway deck reconstruction as well as improved access and safety for pedestrian traffic.
