As part of our Owner’s Engineer role on the Hunts Point Interstate Access Improvement Project, H&H conducted a peer review of the constructability and construction staging plan for replacing the Bruckner Expressway Bridges over Amtrak/CSX. These structures include two eastbound, parallel multi-girder bridges and an existing westbound truss superstructure bridge.
Following this impactful review, H&H was tasked with developing a streamlined alternative conceptual staging scheme. The proposed approach significantly reduced risks to NYSDOT and future design-build teams, minimized construction impacts to adjacent railroads, and simplified both design and construction of the replacement bridges.
The alternative scheme successfully addressed Amtrak/CSX’s major concerns, substantially reduced disruptions to railroad operations, and eliminated the need for shoring or temporary structures within the railroad right-of-way.
The Hunts Point Access Improvement Project is a $1.7B, three-phase project to improve vehicular access between the Hunts Point Peninsula and the Sheridan and Bruckner Expressways, and to address structural and operational deficiencies related to the existing infrastructure. This is the largest design-build project NYSDOT has ever done. The project includes 12 bridges and viaduct structures, and the site covers more than 1.5 miles of existing infrastructure, including highways, expressways, service roads, city streets, parkland, movable bridges, and pedestrian accessways. The project required a full EIS and significant interagency coordination. H&H is serving as Owner’s Engineer and providing design quality assurance engineering for Contracts 1-3.
