Abstract:

On November 18, 1999, cranes lowered into place the last of 202 precast concrete segments that form the main span of the new Sagadahoc Bridge, a $46.6 million crossing that boasts the longest precast balanced cantilever concrete segmental span in the United States, at 128 m (420 ft). Scheduled for completion in October 2000, the Sagadahoc Bridge will replace the Carlton Bridge, a steel truss lift bridge built in 1927. Other innovations incorporated into this Figg engineering project include the design-build approach�a first for the Maine Department of Transportation�and five- and ten-year warranties on parts of the work.
