The Dames Point Bridge (officially the Napoleon Bonaparte Broward Bridge) is a cable-stayed bridge over the St. Johns River in Jacksonville, Florida, United States on the Interstate 295 East Beltway. Construction began in 1985 and was completed in 1989. The main span is 1300feet, and is 175feet high. The bridge was designed by HNTB Corporation and RS&H, Inc. The Massman Construction Company built the bridge.[1]
The bridge's cables are arranged on multiple vertical planes in a slight modification to the harp (parallel) stay arrangement.[2] Main span cables are paired to anchor into the tower in a vertical plane while side span cables pair up to anchor in a horizontal plane such that four cables anchor in each tower at approximately the same elevation.[3]
Until the 2003 completion of the Sidney Lanier Bridge in Brunswick, Georgia, the Dames Point Bridge was the only bridge in the United States to feature the harp stay arrangement.[4]
It remains one of the largest cable-stayed bridges in the United States,[2] [5] with 21miles of cable.[2]
On May 15, 1989, while inspectors were checking the bridge for cracks and fissures, the boom arm holding a bucket snapped, leaving the bucket tilted on its side. One worker fell into the river below and the others were at risk of plummeting 145 feet down. The man in the river suffered a dislocated shoulder but was able to swim to safety. Rescuers rappelled down the side of the bridge to the other three workers and successfully brought them all to safety.[6] [7] The story of this rescue effort was aired on Rescue 911 on September 12 of the same year.[8]
