The complete demolition and reconstruction of three bridges, including two (2) ramps over Route I-287 and one ramp bridge over Route 119. The major work items included staged demolition of the existing concrete decks; structural steel and concrete substructures. Demolition and reconstruction work was performed while maintaining traffic on all three (3) bridges at all times. New construction included driving steel H-piles; soldier piles; lagging and steel sheeting. A redesign of the contract substructure excavation support systems resulted in a substantial saving of time and money. A new noise barrier was constructed that involved extensive foundation drilling, including rock sockets. In excess of fifty thousand cubic yards of rock was blasted and excavated along Route I-287 from cuts as high as one hundred feet. To maintain the contract schedule an extensive amount of work was performed at night including the mainline paving of Route I-287.
