Construction began in 1985 and was completed in 1989.  The main span is {{convert|1300|ft|1}}, and is {{convert|175|ft|1}} high.

==Design==
The bridge's cables are arranged on multiple vertical planes in a slight modification to the [[Cable-stayed bridge#Designs|harp (parallel) stay arrangement]].<ref name=weeks>{{cite web|last=Weeks|first=John|title=Dames Point Bridge|url=https://www.johnweeks.com/cablestay/pages/csb04.html|publisher=johnweeks.com|access-date=May 15, 2012}}</ref>   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.<ref>{{cite web | last1=Podolny | first1=Walter Jr. |title=Concrete Cable-Stayed Bridges |url=https://onlinepubs.trb.org/Onlinepubs/trr/1978/665v2/665v2-015.pdf |access-date=18 July 2018 |page=129}}</ref>

==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.<ref>{{cite web |last1=Archaeological Consultants, Inc. |title=The Historic Highway Bridges of Florida |url=http://www.fdot.gov/environment/pubs/Historic%20Highway%20Bridges%20of%20Florida%202010%20Update.pdf |publisher=Florida Department of Transportation |access-date=18 July 2018 |page=122 |date=December 2012}}</ref>

==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.<ref>"[https://www.news4jax.com/news/2019/03/11/a-look-back-dames-point-bridge-celebrates-30-years/ A look back: Dames Point Bridge celebrates 30 years]," ''News4Jax,'' 11 Mar. 2019</ref><ref>"[https://www.news4jax.com/news/2015/10/30/jacksonvilles-dramatic-rescues-caught-on-camera/ Jacksonville's dramatic rescues caught on camera]," ''News4Jax,'' 30 Oct. 2015.</ref> The story of this rescue effort was aired on ''[[Rescue 911]]'' on September 12 of the same year.<ref>Shatner, William (host), "[https://www.youtube.com/watch?v=hwa_sirrVNs Rescue 911 - Episode 1.2 - Dames Point Bridge Rescue]," ''CBS.''
