Eel Weir Road (CR 4) over the Oswegatchie River. The project consists of replacing the existing four-span superstructure of the Eel Weir Road (CR 4) bridge crossing over the Oswegatchie River with multiple steel girders and cast-in-place concrete deck. The existing concrete abutments and piers will be utilized with reconstructed pier caps and bridge seats and new concrete semi-integral backwalls. Class
