H&H served as prime consultant for the $250 million replacement of the Unionport Bridge, providing study, design, and construction support services for a new twin single-leaf bascule bridge and its approaches. This locally administered, federally funded project required extensive stakeholder coordination, an alternatives development phase, and FHWA design approval.
Replacing the 70-year-old double-leaf bascule bridge presented significant challenges within a highly constrained site surrounded by the Cross Bronx–Bruckner Interchange. The design maintained four lanes of traffic and continuous vessel navigation throughout construction while minimizing impacts to adjacent expressways. Innovative geotechnical and structural solutions allowed the new structure to fit within the existing footprint.
Carrying approximately 60,000 vehicles daily on the Bruckner Expressway Service Road over Westchester Creek, the bridge provides the only direct connection between the Bruckner and Cross Bronx Expressways and the Hutchinson River Parkway. The new bridge enhances safety and multimodal access with the addition of a lane, bikeway, and sidewalk, while its twin bascule spans simplify future maintenance and operations.
Completed in October 2025, the project delivers a 75-year design life, improved service levels, and seamless infrastructure for nearby commercial developments, including a new Amazon distribution facility adjacent to the bridge.
