This article describes the construction of the Dames Point Bridge in Jacksonville, Florida. The $46.6 million contract covers the record-setting 2600 ft. main spans across the St. Johns River. Multiple cranes and special spreader bars are used to lift each rigid cable stay into position after it is assembled. Each stay consists of seven to nine 1 1/4-in., high-strength threaded steel bars in a 6- or 7-in.-diameter rigid steel pipe. The threaded bars carry the dead load weight of the bridge, while the steel pipe participates in carrying the live load stresses after grouting. The 650 ft.-1300 ft.-650 ft. spans are constructed as two balanced cantilevers with each cast-in-place concrete segment being supported by a pair of cable stays. The 1300 ft. center span is the longest cable stayed span in the U.S. and the bridge is the first to be erected using rigid stays.
