NYSDOT Finishes $49M Route 20 Rebuild and Cazenovia Creek Bridge in Erie County

The New York State Department of Transportation has finished major construction on a $49 million reconstruction of U.S. Route 20 (Transit Road) in Erie County, replacing a bridge over Cazenovia Creek that dated to 1929 and widening roughly a mile of the corridor from three lanes to five. Governor Kathy Hochul announced the completion on Wednesday, October 21, and said the work came in on budget and ahead of schedule (Governor's Office).

What Happened

The project covers about one mile of Route 20 between Leydecker Road and Seneca Street (State Route 16), a stretch that crosses the towns of West Seneca, Elma and Orchard Park (Governor's Office). The state said the new bridge would be fully open in time for the next morning's commute, with finishing work, including additional paving and landscaping, continuing over the coming weeks (Governor's Office).

Before the rebuild, this section of Transit Road carried one travel lane in each direction with a center turning lane. It now has a five-lane configuration with two travel lanes in each direction (Governor's Office). The corridor carries more than 25,000 vehicles a day and is a main route for traffic heading to Buffalo Bills games and the Erie County Fair, according to the release (Governor's Office).

What Was Built

The state's description of the finished work includes several distinct pieces of scope, which together explain why a one-mile project reached $49 million:

• Bridge replacement: The nearly 100-year-old Cazenovia Creek bridge, built in 1929, was replaced with a steel girder bridge on three piers with a concrete deck (Governor's Office).
• Architectural treatment: The new structure keeps some of the squared-stone architectural features of the original bridge while adding modern infrastructure and safety improvements (Governor's Office).
• Roadway widening: The road was rebuilt from a three-lane section to a five-lane section with two travel lanes each way (Governor's Office).
• Drainage, signage and signals: New drainage infrastructure, new signage and a new traffic signal were installed along the corridor (Governor's Office).
• Water main: A 36-inch water transmission main next to the bridge was replaced to keep water service reliable for residents of southern Erie County (Governor's Office).
• Bike and pedestrian elements: U.S. Senator Charles Schumer said in the release that the project includes bicycle lanes and safer sidewalks (Governor's Office).

The release does not name the contractor, give a construction start date or provide a full funding breakdown. Senator Schumer said the work drew on millions of dollars in federal funding from the Bipartisan Infrastructure Law, but the state did not publish the split between federal and state dollars (Governor's Office).

Why This Corridor Matters

Transit Road is one of the main north to south arteries in the Southtowns and connects suburban communities with commuters, businesses and shoppers, the state said (Governor's Office). It also sits on the path to Highmark Stadium and the Erie County Fairgrounds, two major event destinations on the corridor (Governor's Office). A two-lane bridge with a turning lane was a choke point on a road carrying more than 25,000 vehicles daily.

Officials framed the project around congestion and safety. Governor Hochul said the completion "fully modernized" the corridor "to reduce bottlenecks." NYSDOT Commissioner Marie Therese Dominguez called it an example of the governor's commitment to public safety, and Erie County Executive Mark C. Poloncarz said the improvements will help reduce congestion and make travel easier (Governor's Office). U.S. Senator Kirsten Gillibrand, Representative Tim Kennedy and Assemblyman Pat Burke also praised the work, and Burke said he would keep advocating for investment along the roadway (Governor's Office).

Where Things Stand in Western New York

The Route 20 completion lands near the end of a busy local construction season. Erie County entered 2026 with a large road and bridge program of its own, which WCG covered in Erie County's 2026 road and bridge construction season. Further north, NYSDOT has also been working on Transit Road in Niagara County, where it started a $13.3 million rehabilitation of Route 78 around Lockport this spring. Together these projects show the state treating Transit Road as a regional corridor rather than a series of isolated repairs.

The project also follows a familiar pattern for aging state bridges in upstate New York: a structure built in the 1920s, a corridor whose traffic has grown well beyond its original design, and a utility line running alongside the crossing that has to be replaced at the same time. Bundling the water main, the bridge and the road widening into one contract limits repeat disruption for drivers and adjacent property owners, even if it raises the headline cost.

Implications for Owners, Developers, Contractors and Subs

• Owners and developers: Added capacity on Transit Road between Leydecker Road and Seneca Street improves access to commercial parcels in West Seneca, Elma and Orchard Park. Retail, medical office and light industrial users that depend on peak hour access should see shorter queues at the creek crossing.
• Heavy civil contractors: The scope here, a steel girder bridge on piers, a widened approach roadway and a large diameter water main, is typical of the bridge replacement work NYSDOT continues to let across the region. Firms that can self-perform structures and coordinate utility relocation remain well positioned.
• Specialty subs: The design's carryover of squared-stone features from the original bridge is the kind of context-sensitive detail that appears on state projects in established communities and can add finish work to a structural job. Signal, drainage and paving subs will stay busy on finishing work in the coming weeks.
• Utilities and municipal partners: Replacing a 36-inch transmission main inside a bridge project is a reminder that water authorities and highway agencies increasingly coordinate scopes, which affects sequencing and traffic control plans.

What to Watch

• Completion of the remaining paving and landscaping over the next several weeks (Governor's Office).
• Whether NYSDOT or Erie County announce further work on adjacent segments of Transit Road, which Assemblyman Burke said he will keep pushing for (Governor's Office).
• The next round of state and federally funded bridge lettings in Western New York as agencies plan their 2027 construction seasons.

Bottom Line

A one-mile, $49 million project replaced a 1929 bridge, doubled through lanes on a corridor carrying more than 25,000 vehicles a day and swapped out a major water main in the same footprint. The state says it finished on budget and ahead of schedule, and the reopened crossing should ease one of the more persistent bottlenecks in the Southtowns.
