Rehabilitation and installation of seismic retrofits for the south grand island bridges and additional safety and pedestrian improvements

The Federal Highway Administration (FHWA) awarded the New York State Thruway Authority a $39 million Project Grant on September 18, 2025, under the Highway Planning and Construction program (CFDA 20.205) to rehabilitate and install seismic retrofits on the twin South Grand Island Bridges (Bridge Inventory Numbers 5043981 and 5043982) crossing the Niagara River on Interstate 190 in western New York. The project will also incorporate additional safety and pedestrian improvements to enhance infrastructure resilience and public safety. Work is scheduled for completion by December 31, 2029.

This infrastructure improvement project represents a significant federal investment in bridge rehabilitation and disaster mitigation, supporting the FHWA's mandate to preserve and improve the nation's highway system. The seismic retrofit component addresses critical structural vulnerabilities while the safety and pedestrian enhancements will improve overall transportation functionality and accessibility along this strategically important regional corridor.
