Bridge Spans Lifted 80 Feet from Barge
The four-lane Jamestown-Verrazano bridge linking North Kingstown and Jamestown, Rhode Island, underwent a 2,400-ton precast bridge span lift between 1990 and 1992. The double-cell box girder used for both the high-level approach spans and the main structure varies in depth from 10 feet to close to 33 feet. The three main spans were cast in place using balanced cantilever construction, and the high level precast approach spans were lifted into place. The work was originally bid to VSL Corp., who redesigned the high-level approach plans to permit span-by-span erection with VSL equipment. The contract was later terminated and reawarded to Atkinson-Kiewit, who decided to follow the VSL redesign, which provided the option of casting pier segments of the approach spans in place.
