State Department of Transportation crews began removing trees along Erie Boulevard East in Syracuse for the Interstate 81 Viaduct project. Parts of I-81 in Syracuse are set to close permanently in November 2026 for demolition and construction.
Why it matters
Trees and brush must be cleared before underground water lines, combined sewer pipes, and drainage trunk lines can be installed and equipment can move in. The work is scheduled in winter to avoid disturbing endangered bats that hibernate in the trees.
Crews may cut trees only between November and April to protect endangered bats that hibernate during winter. The project plans to plant at least 800 trees once construction in the area is complete.
The players
New York State Department of Transportation
The state agency responsible for designing, building, and maintaining New York's highways, including the Interstate 81 Viaduct replacement in Syracuse.
The details
Trees and bushes along I-81 between North McBride Street and Almond Street were removed by Thursday, and encampments beneath the highway were cleared out the same day. Trees near North McBride Street are being removed so crews can demolish the McBride Street ramp to I-690 East.
Timeline
November through April: Window in which tree cutting is permitted
Thursday, November 5, 2026: Trees removed and encampments cleared along Erie Boulevard East
November 2026: Parts of I-81 set to close permanently for demolition
About two years: Eastbound I-690 closure between West Street and North Crouse Avenue
Season Trajectory
Clearing trees along the I-81 Viaduct corridor marks an early physical step in a multi-year replacement of the elevated highway through Syracuse. The sequencing of closures, demolition and replanting will shape how traffic and neighborhoods in the city are affected through the coming years.
Drivers who use eastbound I-690 through downtown Syracuse, which carries about 33,000 vehicles a day, should plan for a closure lasting about two years. Residents near Erie Boulevard East and North McBride Street should expect continued tree and brush removal in those areas.
The takeaway
Syracuse residents and commuters should begin planning alternate routes now, since the I-81 closures and the I-690 detour will reshape daily travel in the city for years. Checking state transportation updates before November 2026 will help avoid delays.
What happens next
Parts of Interstate 81 in Syracuse are set to close permanently in November 2026, and eastbound I-690 between West Street and North Crouse Avenue will close for about two years.
