Pedestrian bridge at night

B. Thayer provided Architectural, Landscape Architectural, and structural design services for a new pedestrian bridge over Route 9A at 46th Street and the Intrepid Museum. The design of the 46th Street Pedestrian Bridge was coordinated with the design of the new Intrepid Museum Visitor's Center to incorporate similar nautical motifs. The pedestrian bridge provides safe access from the east side of Route 9A to recreational facilities on the west side of the highway and ADA access from street and park levels. Design utilized aesthetic treatments in keeping with the local environment. Lighting, landscaping, pavement, drainage and site amenities associated with the bridge were also integrated into the design.

Our Design Team developed structural design of the East Touchdown and west stairs, the main landing structure, composite reinforced concrete deck, ramps, retaining walls, piers, and foundations. All design was completed using finite element analysis of the structure model, including the seismic loading, and utilized STAAD Pro 2000.

Work included coordination with, and approvals by, SHPO. The team also presented to the Visual Task Force which included the Hudson River Park Trust, and also prepared quantities estimates, construction cost estimates, and provision of construction support services.
