Syracuse, N.Y., The biggest road construction project in New York State history is about to get a lot more visible. Phase Two of the I-81 Viaduct Project kicks off this spring, shifting work from behind-the-scenes prep to the streets Syracuse drivers use every day, and bringing months of lane closures, bridge demolitions, and detours across downtown.
Here’s what you need to know before you get behind the wheel.
Phase Two Is Here
After three years of preparatory work, NYSDOT says Phase One contracts are wrapping up. The Brighton Avenue roundabouts are done. Bridge work near the Inner Harbor is finished. The new I-81 to I-481 connection is open and carrying traffic at 65 mph.

Now comes the hard part.
Phase Two will rebuild the corridor from Leavenworth Avenue to Crouse Avenue, construct new interchange connections to West Street, and begin building Business Loop 81, the ground-level roadway that will replace the elevated viaduct. I-690 will be reconstructed entirely through the downtown corridor, including 30-foot-deep underground work to replace aging water and sewer lines beneath Erie Boulevard and Salina Street.
NYSDOT expects the elevated viaduct to fully close by the end of 2026, with demolition continuing through 2027 and 2028.
What’s Closed Right Now
Court Street Bridge (March through November 2026): Court Street is closed between Sunset Avenue and Genant Drive for demolition of the existing bridge over I-81 and construction of a new, longer span. Westbound traffic detours south on Lodi Street to North Salina Street, then west on Catawba and Spencer streets to North Clinton. Eastbound traffic reverses the route.
I-81 Southbound lane reductions: One lane between Hiawatha Boulevard (Exit 23) and Franklin Street (Exit 20) on weekdays, 9 a.m. to 3 p.m., through early April for Court Street Bridge demolition work.
South Bay Road, Cicero: Closed to southbound traffic between East Pine Grove Road and East Circle Drive through May 15 for bridge approach construction. Northbound stays open.
The Massive Contract 6
Early this year, NYSDOT will award Contract 6, valued at over $900 million, the single largest contract in DOT history. Project Director Betsy Parmley called it three times larger than any other contract in the program. This contract covers the most disruptive phase: tearing down the 1.4-mile elevated highway and building the street-level Community Grid in its place.
The $251 million Contract 5, awarded to Salt City Constructors, is already underway, transitioning the southern end of the corridor into pedestrian-friendly streets.
Federal Funding at Risk
A shadow hangs over the project’s finances. The federal budget bill currently before Congress would cancel more than $3 billion from the U.S. DOT’s Neighborhood Access and Equity Program, including more than half of a $180 million grant awarded to NYSDOT in 2023 for the I-81 project. State officials say the project remains on budget at $2.25 billion but are watching potential tariff impacts closely.
I-81 By The Numbers
Commuter Survival Guide
Download the I-81 Connect app. It pushes real-time alerts on lane closures, ramp changes, and detours before you leave the house. No excuse not to have it.
Avoid I-81 southbound through downtown between 9 a.m. and 3 p.m. on weekdays. That single-lane squeeze near Exit 20 will add serious time to your commute. Use I-481 as your bypass.
Rethink your Court Street route. With the bridge closed through November, anyone cutting between University Hill and the Northside needs to build in extra time through the Salina Street detour.
Plan for overnight closures. NYSDOT regularly shuts down I-81 lanes between 7 p.m. and 6 a.m. for demolition work. Late-night drivers should check 511NY.org before heading out.
Give yourself 15 extra minutes. That’s the unofficial rule for any route touching downtown, the Crouse-Irving corridor, or the Erie Boulevard area through the end of the year.
The Bigger Picture
The viaduct, completed in the 1960s, displaced more than 1,300 families and carved a concrete wall through Syracuse’s 15th Ward. Its removal is meant to undo decades of damage, reconnecting neighborhoods from University Hill to downtown while creating a street-level grid that prioritizes pedestrians, cyclists, and local businesses over through-traffic.
NYSDOT has hired an industrial hygienist and installed air pollution monitoring systems around the demolition zone. A community health hotline is active for residents with concerns about dust, noise, or hazardous materials like lead and asbestos in the old structure.
Spring 2026 marks the moment this project stops being something Syracuse talks about and starts being something Syracuse lives through. Buckle up.
