This project consists of the replacement of a 39-foot long single span steel bridge. The bridge was constructed in 1940 and connects two islands off the Deer Isle Peninsula. The existing superstructure was in such poor condition that through girders with floor beams were installed to support the existing girders.
Fuss & O’Neill evaluated various superstructure and substructure replacement options. These included a 75-foot span bridge with precast concrete NEXT beams or box beams on integral abutments with drilled micropiles. The new longer span will improve the hydraulics. The new abutments would be constructed behind the existing abutments to avoid work in the water. Maintenance of traffic options include a bridge closure and detour using Accelerated Bridge Construction (ABC) techniques, an off-alignment and a temporary bridge.
