Bridge Rehabilitation Project on Route 12A in Claremont

Reconstruction of the bridge will impact traffic thru August of 2025.

The New Hampshire Department of Transportation (NHDOT) is continuing work on a bridge rehabilitation project on the NH Route 12A bridge over the Sugar River in Claremont, NH.  
This project will replace the superstructure (structural steel plate girders and bridge deck), road work before and after the bridge, substructure repairs, and the installation of scour countermeasures to protect piers and abutments.

On November 14, 2023 the bridge will be restricted to one lane of traffic thru August of 2025.  Lane width restriction of 11’-0” will be in place.

Electronic signals will be utilized to control one lane of alternating traffic over the bridge and travelers should expect new traffic patterns.  Message boards will be used to notify the traveling public as the work progresses. 

Motorists should remain alert while traveling through the work zone and obey all posted signs. Motorists are also encouraged to sign up for free, real-time construction and traffic related messages (text or email) from  

A detour will be in place for daytime traffic closures in June of 2024 for setting of structural steel. Detour signing will be in place to direct motorists around the closure.
