The bridge carries Interstate 90 over the Hudson River between Albany and Rensselaer counties. 

The project will involve rehabilitation of the Patroon Island Bridge and all the ramps comprising the I-90 interchange with I-787. Work will include replacing the bridge decks and bearings, repairing steel and painting the bridges, as well as replacing or repairing the substructure of the interchange. The steel truss and substructures will also be strengthened to meet current seismic requirements. Pre-cast concrete deck panels will be used to speed construction.
