| Description | Replacement of a through-girder bridge over a busy commuter railroad in the village of Tuckahoe presented challenges for NYSDOT: maintaining two way traffic, conducting all work between 2 and 4 AM on weekends to limit disruptions for rail commuters and adjacent stores, maintaining utility lines while relocating them on the new bridge, and raising the railroad vertical clearance five inches without affecting the street profile. NYSDOT chose a commercial system of precast prestressed concrete/steel composite superstructure modules that allowed for smaller beams than conventional construction, which helped attain the increased vertical clearance and had a short installation time. |
