Route 113 Bridge in Lyme to Close for Rehabilitation

The New Hampshire Department of Transportation (NHDOT) will close the East Thetford Road, Lyme, NH/VT Route 113 bridge over the Connecticut River on Thursday, April 27, 2023 to begin rehabilitation work. The bridge will be reopened in October 2024.  
  
Detour signs will direct traffic to cross the Connecticut River upstream via Bridge Street (Route 25A) in Orford, NH/Fairlee, VT, or downstream via West Wheelock Street/VT Route 10A in Hanover, NH/Norwich, VT. Motorists should remain alert while traveling along the detour and in the vicinity of the construction zone. 
  
The project rehabilitates the existing State Red List bridge that carries East Thetford Road over the Connecticut River between the Towns of Lyme, NH and Thetford, VT.  The existing bridge was built in 1937 and is a two-span steel high Parker truss with equal spans of approximately 232-feet.  The bridge is currently posted for a reduced weight limit of 15-tons.  The work includes: 
 

• Rehabilitation of the bridge abutments and pier. 
• Replacement of the concrete bridge deck, expansion joints, curbs and bridge rail. 
• Replacement of exterior stringers, end floor beams and floor system lateral bracing. 
• Cleaning and painting the structural steel and bridge shoes. 
• Full depth reconstruction and drainage improvements of the roadway approaches to the bridge.
