Road Work on I-93 in Plymouth, Campton, and Thornton

This work will require temporary, daytime lane closures for several months.

The New Hampshire Department of Transportation (NHDOT) will begin road work on I-93 at mile marker 81.4, just north of the Exit 26 on ramp in Plymouth, on Monday, March 25, 2024. 
This project will resurface and improve over 16 miles of the highway from Plymouth to Thornton, northbound and southbound, and includes the replacement of guardrail, adjustments to drainage structures, replacement of signs, and a CCTV pole installation at Exit 28. The project will also resurface the ramps at Exit 27 and Exit 28, and all of the emergency crossovers within the project limits. 
This work will require left and right lane closures, as needed, and the speed limit during work hours will be reduced to 60 MPH. Uniformed officers may be present to help keep the work zone safe for the crews and the traveling motorists. The guardrail work will continue north to the project limits at mile marker 88.4 when the crews will begin the work on southbound I-93. The guardrail work is expected to take a few weeks to complete. 
Work at the Exit 27 and 28 ramps, to include resetting the granite curb, is expected to begin in June which may result in ramp closures with detours for short durations. Paving operations throughout the season will require lane closures and may cause slower than normal travel. Please plan ahead and slow down when traveling through the work zone. 

Message boards and traffic control devices will be used to direct and inform local traffic. Motorists are encouraged to sign up for free, real-time construction and traffic related messages (text or email) from
