Construction Update

Colchester Exit 17 Project

Colchester NH 028-1(31) [National Highway]

DATE: Friday, March 21, 2025

TRAFFIC IMPACT AND DURATION: From Monday, March 24, through Friday, March 28, Interstate 89 (I-89) will be intermittently reduced to a single lane in both directions near Exit 17 during off-peak hours: 6 a.m. to 3 p.m. on I-89 northbound and 9 a.m. to 8 p.m. on I-89 southbound.

The I-89 northbound off-ramp slip lane to U.S. Route 2 (U.S. 2) westbound will remain closed 24/7. Motorists can turn right or left onto U.S. 2 at the signalized intersection.



Motorists should slow down, use caution, and pay attention to road signs while traveling through the work zone.

CONSTRUCTION ACTIVITIES: Next week, crews will mobilize to the project area for the 2025 construction season, install temporary traffic control message boards, signage, and devices, conduct general clean-up, and complete line striping along the I-89 southbound deceleration lane and off-ramp.

Crews will mobilize to the Exit 17 interchange along I-89 in Colchester, VT next week.

LOCATION: The project limits include the segment of U.S. 2 starting just east of Jasper Mine Road and extending nearly half a mile east to its intersection with U.S. 7 at Chimney Corner, the segment of U.S. 7 starting just south of the Shell Gas Station/Simon’s Chimney Corner Store and extending just over half a mile north to its intersection with Wiley Road, and the Exit 17 interstate ramps and the portion of I-89 bounded by them.
