In addition, independent utility companies are on-site conducting independent utility work along U.S. 2/7 throughout the project limits, under lane closures.


Motorists should expect significant delays when traveling through the work zone and along adjacent roadways. Please plan ahead, leaving plenty of additional time to get to and from your destination. Whenever possible, consider alternate routes or other forms of transportation such as carpooling, ridesharing, transit, biking, or walking. Drivers should slow down, use caution, and follow flaggers and road signs.

CONSTRUCTION ACTIVITIES: Crews will continue work on the stormwater ponds near the I-89 southbound on-ramp and on the east side of U.S. 2/7 north of Hercules Drive. This work will take place off the roadway. Additional drainage work will take place along U.S. 2/7 near Whitcomb Street and Champlain Farms and near Rathe Road and the Park and Ride.

No blasting activities are anticipated to take place next week, with blasting activities anticipated to resume the week of December 1.
