Maine’s first design-build project, Sagadahoc Bridge, opened to traffic in July 2000, one month ahead of schedule. The 420’ main span was the longest precast segmental span built in the balanced cantilever fashion in the United States at that time. A design charette with the community provided the public an opportunity for input on various features of the bridge that were beyond the requirements of the contract, a very unusual approach in a design/build project. The bridge has earned four awards, including the Design Build Institute of America’s 2001 Design Build Excellence Award.
