The New York State Thruway Authority has started a $54.4 million steel repair and seismic retrofit project on the South Grand Island Bridges, the twin I-190 truss arch spans over the Niagara River between Grand Island and the Town of Tonawanda. Work began July 17, 2026 and is scheduled for completion in late 2028 (Office of the Governor of New York).

More than 70 percent of the funding — $39 million — comes from a 2024 federal grant the Thruway Authority received through the U.S. Department of Transportation's Promoting Resilient Operations for Transformative, Efficient and Cost-saving Transportation (PROTECT) program, funded by the Bipartisan Infrastructure Investment and Jobs Law (Office of the Governor of New York).

Scope of Work

The project is a structural preservation and resilience package rather than a replacement. Listed scope includes seismic retrofits to both bridges, structural steel repairs, strengthening of key structural elements, improvements to seismic performance, friction treatment of the deck surfaces to improve wet-weather safety, replacement and reopening of the sidewalk on the southbound bridge, catwalk access repairs, and fall protection improvements for maintenance personnel (Office of the Governor of New York).

Thruway Authority Director of Infrastructure Management John Boser added bearing replacement and superstructure strengthening to the public description of the work (BTPM). Construction will be phased over multiple seasons to help maintain traffic flow, with an overall duration of about three years (WKBW).

Why These Bridges

The two spans carry one direction of I-190 each. The southbound bridge was completed in 1935 and the northbound bridge in 1963, and more than 68,000 vehicles cross daily (Office of the Governor of New York). A 91-year-old primary crossing carrying that volume, with no practical parallel route for commercial traffic, is exactly the kind of asset where preservation spending is cheaper than replacement — for now.

U.S. Sen. Charles Schumer, who credited the federal law for the $39 million, noted that "age and deterioration have taken a toll on many sections of the bridge" (Office of the Governor of New York). Thruway Authority Executive Director Frank G. Hoare called the spans "a vital transportation link for Western New York" and framed the project as an investment in safety, reliability and long-term resilience (Office of the Governor of New York).

Asked about the bridges' remaining service life, Hoare said the "shelf life can continue on as long as" necessary maintenance is performed and the structures remain safe (BTPM).

The Wider Buffalo Division Program

Thruway leaders came to Buffalo on Aug. 5, 2026 to review active work, and the figures they disclosed give contractors a usable picture of the regional pipeline:

• $1.1 billion in Thruway work currently underway statewide, of which $314 million is in the Buffalo Division (BTPM)
• Roughly $670 million planned for Western New York roads and bridges over the next five years under the 2026–2030 Capital Plan; the Buffalo Division covers I-90 from Rochester to the Pennsylvania border and I-190 from Cheektowaga to Niagara Falls (WKBW)
• A $67 million North Grand Island Bridges project that began in 2023 and is expected to finish this year (BTPM)
• $62 million of work on I-190 in Buffalo, expected to take two more years, and a $64 million I-90 project between Buffalo and Cheektowaga (BTPM)

Statewide, the Authority's approved 2026 budget schedules more than $600 million in capital contracts to be awarded during the year — an increase of more than $133.5 million over 2025 projected totals — and the $2.8 billion 2026–2030 Capital Plan covers replacement or preservation of 150 of the system's 819 bridges (about 18 percent) and resurfacing of more than 1,500 of 2,800 lane miles (roughly 60 percent) (Office of the Governor of New York).

Why It Matters to Construction Professionals

Two things stand out. First, seismic retrofit is now a funded category in New York, not just a West Coast discipline. Bearing replacement, member strengthening and connection retrofits on riveted and welded truss arches require specialized heavy-civil capability, engineered temporary support, and rigging in a river environment. That narrows the bidder pool considerably.

Second, resilience money is doing the work. The PROTECT program supplied more than 70 percent of the project cost (Office of the Governor of New York). Contractors and owners tracking future opportunities should watch resilience-specific federal formula and discretionary programs rather than only conventional bridge funding.

Implications for Owners, Contractors and Subcontractors

For heavy-civil general contractors, roughly $670 million of planned Western New York Thruway work over five years is a meaningful base load, and it is concentrated in preservation: resurfacing, deck work, steel repair and bridge rehabilitation (WKBW). Firms positioned for milling and paving, concrete repair and structural steel retrofit should expect steady lettings.

For subcontractors, the specialty scopes on projects like this include containment and lead-paint abatement on older steel, industrial coatings, bearing and jacking systems, marine access, high-friction surface treatments, and fall-protection systems for permanent maintenance access (Office of the Governor of New York).

For owners of private assets along the I-190 and I-90 corridors, multi-season phased work with off-peak closures means predictable but recurring access constraints (BTPM). Logistics-dependent facilities should build that into delivery planning through 2028.

What to Watch Next

The most consequential item is not this contract — it is the federally funded Planning and Environmental Linkages (PEL) study the Thruway Authority is conducting on the future of the Grand Island bridges. The study evaluates long-term transportation needs, traffic patterns, infrastructure conditions and potential concepts, will not recommend a preferred alternative, and is expected to be complete by July 2027 (WKBW).

Hoare said the study will allow the Authority over the next two years to consider the future of the crossings and how to handle aging infrastructure, severe winters and a growing population (WKBW). A PEL study is the front end of the environmental process for a potential major capital project. If replacement concepts advance, Western New York would be looking at a program an order of magnitude larger than the current $54.4 million retrofit.

Also watch the 2026 letting schedule. With more than $600 million in statewide capital contracts planned for award this year, bid opportunities should continue into the fall (Office of the Governor of New York). Note that no contractor has been publicly identified for the South Grand Island project in the available sources.

Bottom Line

A $54.4 million retrofit is now extending the life of two I-190 spans built in 1935 and 1963 that carry more than 68,000 vehicles a day, with $39 million of federal resilience funding covering most of the cost and completion set for late 2028 (Office of the Governor of New York). The larger signal for contractors is a Buffalo Division program of roughly $670 million over five years — and a PEL study due July 2027 that could eventually put the Grand Island crossings themselves on the table (WKBW).
