New Hampshire Department of Transportation —Stewartstown, NH Bridge Rehabilitation

Originally built in 1931, the award-winning Stewartstown Bridge ultimately needed a complete overhaul to ensure all vehicle weight loads could be accommodated safely. The New Hampshire Department of Transportation’s (NHDOT) $5.1 million rehabilitation project completely removed the bridge’s concrete deck and asphalt overlay, replacing it with a lightweight concrete bare deck. NHDOT also replaced select bent steel components and installed additional cover plates on the arches. It also replaced outdated materials to protect the structure and bring up to present-day code. The bridge is now safer and no longer has any weight restrictions, providing access for commercial trucks to haul freight across the state line into Vermont.
