The snow is melting, the cones are multiplying, and the $2.25 billion question is back: how bad will your commute get this year? Here is every project you need to know about — and the detours that might save your sanity.
If you drove through Syracuse last year and thought the orange barrels were bad, buckle up. Spring 2026 marks the beginning of Phase Two of the I-81 Viaduct Project — the point where construction moves off the elevated highway and onto the streets you actually use every day. Combined with bridge replacements, Thruway paving, county road projects, and a statewide $800 million resurfacing blitz, this construction season is shaping up to be the most disruptive in Syracuse history.
We mapped it all out so you can plan ahead.
The Big One: I-81 Viaduct Project Enters Phase Two
There is no sugarcoating this. The largest construction project ever undertaken by the New York State Department of Transportation is about to get a lot more visible.
Phase Two shifts the work from the elevated structure — where crews have been building new ramps and connections for the past two years — down to the surface streets that will eventually become the Community Grid. NYSDOT will rebuild the corridor from Leavenworth Avenue to Crouse Avenue, constructing new interchange connections to West Street and the future Business Loop 81, the ground-level boulevard that will replace the elevated highway once it comes down.
Here is what that means in practice: I-690 will be reconstructed entirely through the downtown corridor. Erie Boulevard and Salina Street will be torn up for massive underground utility replacement — a new mile-long drainage trunkline, plus water and electric lines — with crews digging as deep as 30 feet, working block by block. The Bear Street on-ramp to I-690 westbound closed on March 30 and will stay closed for approximately one month. Construction of a new off-ramp from I-690 westbound to Burnet Avenue begins this spring, eventually serving as a key access point for commuters heading to the medical and university corridor from DeWitt and Manlius.
The numbers are staggering: eight separate contracts, more than 15 million pounds of structural steel in the first five contracts alone, and a total price tag of approximately $2.25 billion. Contracts 3, 4, and 5 — all on the interior portions of the city — are now underway and will run through late 2026 and into early 2027.
The elevated viaduct itself? NYSDOT plans to close part of the 1.4-mile structure by the end of 2026, with the remainder coming down in 2027 and 2028. The full Community Grid is targeted for completion in 2028.
What to watch for: A new I-81 off-ramp to East Colvin Street is expected to be completed by year’s end, giving northbound drivers another exit before downtown. The new Crouse Avenue westbound exit ramp on I-690 should open mid-2026, providing a direct connection to University Hill — the largest employment hub in Syracuse.
One wildcard: federal funding. NYSDOT has not said how proposed cuts to federal transportation funding could affect the project’s timeline. The current federal budget bill under consideration would cancel more than $3 billion in unobligated U.S. DOT funds, including more than half of a $180 million grant awarded to this project in 2023.
I-690: Lane Reductions and Bridge Work
Even if you avoid downtown, I-690 will test your patience this spring. Bridge work between Exit 19A (Thompson Road) and Exit 18 (Midler Avenue) is already reducing the westbound lanes to one during daytime hours — 9 a.m. to 3 p.m. — through at least early April. The work is weather-dependent, meaning delays could stretch longer.
The larger I-690 reconstruction through the downtown corridor, part of the I-81 project’s Phase Two, will rebuild bridges, widen lanes, and add bigger shoulders along the entire stretch from Catherine Street to Bridge Street. Crouse Avenue and Irving Avenue will both be improved to support three lanes of two-way traffic, a significant change that will reshape how drivers access downtown, area hospitals, and Syracuse University.
The total cost for the I-690 corridor work: between $330 million and $407 million.
I-481 Becomes I-81: The Redesignation You Need to Understand
This is the change that will confuse out-of-towners for years. As part of the viaduct removal, I-481 — the bypass loop east of Syracuse — is being redesignated as the new I-81. The current route of I-81 through downtown will become I-81 Business. Both interchanges where the two highways meet are being reconstructed with expanded ramps to handle heavier traffic, and the stretch of I-481 between Exit 89 (I-690) and Exit 90 (Kirkville Road) is being widened to three lanes in each direction.
Most suburban I-481 work was expected to wrap up by mid-2026, but the Kirkville Road eastbound on-ramp to I-481 southbound in DeWitt is currently closed during daytime hours (9 a.m. to 3 p.m., weekdays, through early April) for bridge work over the CSX railyard.
NYS Thruway: Paving and Bridge Replacements
The Thruway Authority has its own slate of Syracuse Division projects that will overlap with the I-81 chaos. Pavement replacement is planned from Electronics Parkway (Exit 37) to I-690 (Exit 39) — a stretch used daily by thousands of commuters between the western suburbs and downtown. The Thruway bridge over the CSX Railroad in Geddes is also being replaced, along with rehabilitation of bridges over Onondaga Parkway and the Onondaga Lake Outlet.
These projects are separate from the I-81 work but feed into the same already-stressed highway network. If you use I-90 to connect to I-690 or I-481, expect delays at interchange zones through the construction season.
County and Local Projects
It is not just the interstates. Onondaga County has a full plate of its own.
U.S. Route 11 Bridge Over Oneida River (Brewerton)
This $33.6 million replacement project in the Town of Cicero is targeting completion by fall 2026. The aging bridge carries an estimated 13,000 vehicles daily through the Hamlet of Brewerton and serves as a critical north-south link between Onondaga and Oswego Counties. Expect continued lane restrictions and possible detours through the summer.
Onondaga Boulevard (CR 240) Improvement
The county is resurfacing Onondaga Boulevard between Fay Road and Velasko Road — a $7.5 million project that includes a lane reduction from four lanes to three on the western end, new pavement overlay, and traffic signal improvements. The lane diet is a safety measure, but it will change traffic flow for drivers heading to and from the Southside and Westside.
Seventh North Street (CR 45) Paving
From the Syracuse city boundary to Electronics Parkway in the Town of Salina, this two-course pavement overlay will come with minor drainage improvements. Expect lane closures along this busy suburban connector.
Buckley Road Paving
A $3.5 million paving project along Buckley Road will add to the construction in the northern suburbs near the I-81/I-481 interchange area — already a hotspot for I-81 project detour traffic.
Troop K Road Bridge Replacement (Manlius)
The 95-year-old bridge over a tributary of West Branch Limestone Creek is finally being replaced by county forces. It is a smaller project, but if your commute takes you through eastern Onondaga County, note that this road may see closures.
Drainage Replacement: Kreischer Road to Hamilton Street
Approximately 4,500 feet of deteriorated steel pipe is being replaced with high-density polyethylene pipe and new drainage structures — necessary infrastructure work that will mean localized road closures.
The Statewide Paving Blitz
On top of all of this, Governor Hochul announced an $800 million statewide road resurfacing program for 2026 — the largest NYSDOT paving investment in history. Central New York’s share: $25.3 million. That translates to crews on local state routes throughout the spring and summer. Combined with NYSDOT’s core paving program, expect more than 250 pavement renewal projects and over 4,000 lane miles of work statewide.
Bird’s-eye view of the greater Syracuse metro area showing all active and planned 2026 construction zones. Color coding: RED = major delays expected (I-81 downtown corridor from Colvin Street to I-690 interchange; I-690 from Catherine Street to Bridge Street; Erie Boulevard/Salina Street underground utility work). ORANGE = moderate delays (I-481/I-81 interchange reconstruction zones at Cicero and DeWitt; Thruway Exit 37–39 paving; Route 11 Brewerton bridge; Onondaga Blvd lane reduction). YELLOW = minor/intermittent delays (Buckley Road paving; Seventh North Street overlay; Kirkville Road ramp closure; Troop K Road bridge). Key highways labeled: I-81, I-90, Route 690, Route 481, Route 5, Route 11. Landmarks for orientation: Destiny USA (northwest of downtown), Syracuse University (University Hill, southeast of downtown), Downtown Syracuse (center), Syracuse Hancock International Airport (northeast). Each construction zone includes a callout box with: project name, expected duration (e.g., \”I-81 Phase Two: Spring 2026–2028\”), and recommended detour route (e.g., \”Use I-481 bypass to avoid downtown corridor\”).
Your Detour Survival Guide
We talked to regular commuters, checked NYSDOT’s published detour routes, and drove the alternates ourselves. Here are the five worst bottleneck zones and how to get around them.
Bottleneck 1: I-81 Through Downtown (Colvin Street to I-690)
The problem: Phase Two construction narrows lanes and shifts traffic patterns as the Community Grid takes shape. Once the viaduct closes later this year, this route disappears entirely.
Your detour: Take I-481 (soon to be the new I-81) around the east side of the city. Connect via I-690 east or the northern interchange at Cicero. Add 10–15 minutes during peak hours, but you avoid the worst of it.
Time-of-day tip: Avoid 7–9 a.m. and 4–6 p.m. Midday travel (10 a.m.–2 p.m.) moves reasonably well.
Bottleneck 2: I-690 Westbound Through Downtown
The problem: Bridge work and reconstruction reduce lanes. The Bear Street on-ramp closure forces merging traffic onto alternate entry points.
Your detour: From the eastern suburbs, take Route 5 (East Genesee Street) or Route 92 through Fayetteville and into the city on surface streets. From University Hill, use the new Crouse Avenue ramp to I-690 eastbound, then loop via I-481 if heading west.
Time-of-day tip: Westbound afternoons (3–6 p.m.) are the worst. Morning eastbound is manageable.
Bottleneck 3: I-481 at DeWitt (Kirkville Road / CSX Bridge Work)
The problem: Daytime ramp closures and lane reductions during bridge work over the CSX railyard.
Your detour: Use Exit 4 (Route 92/Manlius) or Exit 3 (Jamesville Road) to bypass the DeWitt interchange. Carrier Circle to Bridge Street is a functional surface-street alternative.
Time-of-day tip: Closures run 9 a.m.–3 p.m. weekdays. Early morning and evening commuters should be unaffected.
Bottleneck 4: Route 11 at Brewerton
The problem: The Oneida River bridge replacement funnels 13,000 daily vehicles through a construction zone with lane restrictions.
Your detour: Take I-81 north to the Route 49 exit, then Route 49 west to Caughdenoy Road south. Or use Route 31 through Bridgeport as an east-west alternate.
Time-of-day tip: Weekday mornings and Friday afternoons (summer lake traffic) are the worst windows.
Bottleneck 5: Thruway (I-90) Exit 37–39 Paving
The problem: Pavement replacement on the Thruway between Electronics Parkway and I-690 affects a key suburban-to-downtown corridor.
Your detour: Exit at Exit 36 (Waterloo/Syracuse) and use Route 5 through Camillus, or exit at Exit 39 and take I-690 from there. Overnight work means most lane closures hit between 8 p.m. and 6 a.m.
Time-of-day tip: Daytime travel should be mostly normal. Watch for overnight and weekend closures.

Tools to Stay Ahead of It
NYSDOT’s I-81 Connect app provides real-time lane closure alerts, detour maps, and ramp status updates specific to the viaduct project. It is the single best resource for day-to-day changes.
For everything else — county projects, Thruway work, accidents, and real-time traffic conditions across the full Syracuse metro — bookmark cnysignal.com/roads/. We aggregate NYSDOT advisories, 511NY data, and live camera feeds into one dashboard so you do not have to check five different sources.
This is going to be a long construction season. But these projects — especially the Community Grid — are rebuilding infrastructure that has needed attention for decades. The 1.4-mile elevated highway that divided Syracuse neighborhoods since the 1960s is finally coming down. The pain is temporary. The city on the other side of it will look very different.
Just maybe leave 20 minutes early until then.
