Exit 16 DDI

DATE: Friday, March 27, 2026


TRAFFIC IMPACT AND DURATION: From Monday, March 30, through Friday, April 3, between 6 AM and 3 PM, the following traffic impacts will be in effect:

  • single lane closure along the west side of U.S. Route 2/7 (U.S. 2/7) from Whitcomb Street to Mountain View Drive,
  • intermittent single lane closure along the east side of U.S. 2/7 from South Park Drive and the Interstate 89 (I-89) southbound on-ramp,
  • intermittent lane width reductions and potential intermittent lane closures along the I-89 northbound off-ramp.


Motorists should expect significant delays when traveling through the work zone and along adjacent roadways. Please plan ahead, consider alternative routes, or use other forms of transportation (carpooling, ridesharing, transit, biking, or walking). Drivers should slow down, use caution, and follow flaggers and signage. 

CONSTRUCTION ACTIVITIES: Next week, crews will be working along the west side of U.S. 2/7 between Whitcomb Street and Mountain View Drive widening the roadway and constructing the slip lanes for the I-89 southbound off-ramp and the I-89 northbound on-ramp. Crews will be installing overhead sign foundations along U.S. 2/7 between South Park Drive and the I-89 southbound on-ramp and along the I-89 northbound off-ramp.

LOCATION: U.S. Routes 2/7 in Colchester starting at the Winooski town line and continuing north for 1.05 miles to Sunderland Woods Road.
