A $67 million rehabilitation project is underway to improve the structural integrity, safety, and long-term performance of the North and South Grand Island Bridges, which carry I-190 across the Niagara River between Buffalo and Niagara Falls. These vital spans support more than 52,000 vehicles daily and serve as key connectors in the region’s transportation network. The southbound bridges, built in 1935, are listed as a Nationally and Exceptionally Significant Structure on the Federal Interstate Highway System. Their northbound companions were added in 1960 to accommodate rising traffic demand.

Work on the North Grand Island bridges—each 4,025 feet long with eleven truss spans and five girder spans—includes repairing deteriorated gusset plates, truss components, and bracing, along with seismic upgrades and full lighting replacements. The South Grand Island bridges, measuring 3,385 feet with five truss spans and twenty-two approach spans, are receiving similar lighting improvements and the installation of viscous dampers as part of a seismic retrofit. Additional work includes jacking and scaffolding, steel painting, and traffic control measures to maintain vehicle flow during construction.

Our team is providing complete construction inspection services for this complex, multi-phase effort. Responsibilities include daily site monitoring, documentation of structural repairs, and oversight of scaffolding, jacking operations, and traffic control to ensure safe work within an active travel corridor.
