Design-Build Mario M. Cuomo Bridge Crossing
HVEA was a subconsultant to HDR, the prime design consultant to the Tappan Zee Constructors consortium of Fluor, American Bridge Company, Granite Construction Northeast, and Traylor Bros.
This five-year project constructed twin cable stayed main spans with eight traffic lanes, extra-wide shoulders, and a dedicated multi-use path for pedestrians and bicycles. The bridge was designed for a 100-year service life and is mass-transit-ready for bus rapid transit on the span or for commuter or light rail on structures between the two spans.
HVEA designed a bridge carrying the Shared Use Path (SUP) on the Rockland landing over a Maintenance Road and redesigned three retaining walls measuring over 1,600’ in length and 22’ high with moment slabs and a horse wall on top. These retaining walls ranged from supporting a bike path to one supporting I-287W/I87N on the Rockland side to provide the contractor with a more economical wall type for this project. Also designed concrete deck panels for the SUP overlook areas (Belvederes) and the signing and striping for the entire corridor. We also performed shop drawing reviews for retaining walls, rebar for moment slabs / concrete barrier, and for a permanent maintenance platform pier that extends out into the Hudson River.
Project tasks included:
- Bridge design (prestressed concrete)
- Signing and striping design (including catwalk safety signs)
- Concrete bridge deck panel design / layout
- Redesign of Retaining Walls
- Construction Services (Shop drawing Review)
