The Dames Point Bridge (officially the Napoleon Bonaparte Broward Bridge) is a cable-stayed bridge over the St. Johns River in Jacksonville, Florida on the Interstate 295 East Beltway. Construction began in 1985 and it was completed in 1989. The main span is 1,300 feet (396.2 m), and is 175 feet (53.3 m) high. The bridge was designed by HNTB Corporation and built by Massman Construction Company. The bridge carries Interstate 295 which makes it become part of the bridges on the interstate highway system.
Until the completion of the Sidney Lanier Bridge in Brunswick, Georgia in 2003, it was the only bridge in the United States to feature the harp (parallel) stay arrangement. The cables are arranged on multiple vertical planes, making a slight modification to the harp arrangement. Main span cables are paired to anchor into the tower in a vertical plane. Side span cables pair up to anchor in a horizontal plane. By doing this, four cables anchor in the tower at approximately the same elevation.
On May 15, 1989, inspectors were reviewing the bridge for cracks and fissures when the boom arm holding up a bucket snapped, leaving the bucket tilted on its side and the workers at risk of plummeting hundreds of feet down to the river below. Rescuers rappelled down the side of the bridge to the workers and successfully brought all of them back up to safety. The story of this rescue effort was aired on Rescue 911 on September 12 of the same year.
