| Description | Building a pedestrian bridge in the village of Croton-on-the-Hudson involved site restrictions, a requirement for aesthetic design, and the need to limit disruption on a heavily traveled highway and a major commuter railroad. NYSDOT chose two commercial prefabricated composite superstructure spans with concrete parapets to bridge the 4-lane highway, service road, and five sets of railroad tracks. Twelve-inch diameter precast piles support 3-section piers made of precast boxes stacked vertically and post-tensioned to a cast-in-place concrete footing. Ramps are 35-foot-long precast concrete units and 20-foot precast stair sections, supported directly on precast columns with cast-in-place seats. Precast concrete's many available architectural treatments enabled meeting project aesthetic goals. |
