Design
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]
Superlatives
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 21 miles (34 km) of cable.[2]

Accident
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]
