Temporary Daytime Closure of Route 12A Bridge in Claremont

Motorists will be detoured during the day for three to four days.

The New Hampshire Department of Transportation (NHDOT) is beginning the next phase of rehabilitation work and will fully close the NH Route 12A bridge over the Sugar River in Claremont, during the day, for at least three days. 
Beginning on Tuesday, April 2, 2024, the bridge will be fully closed to traffic for the installation of new structural steel girders in the southbound lane (Phase 1 construction).  A detour will be in place for three days from 7:00 am to 7:00 pm. The work may also require closing the bridge on Friday, April 5, 2024. A signed detour will direct motorists around the closure. 
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  
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.
