The Old Roosevelt Bridge (also called the St. Lucie River Bridge) is a bascule bridge that carries the old Dixie Highway (County Road 707) across the St. Lucie River in Stuart, Florida. The current bridge was built in 1964 and is a low-level bascule bridge.
History
The first bridge built at this site to carry the Dixie Highway over the St. Lucie River was a swing bridge in 1918. This first bridge was named the Henry Flagler Bridge, named for the founder of the parallel Florida East Coast Railway. The route over the bridge would receive the designation of US 1 in 1926.{{cite map |author1= Bureau of Public Roads |author2= American Association of State Highway Officials |date= November 11, 1926 |title= United States System of Highways Adopted for Uniform Marking by the American Association of State Highway Officials |url= https://commons.wikimedia.org/wiki/File:United_States_System_of_Highways_Adopted_for_Uniform_Marking_by_the_American_Association_of_State_Highway_Officials.jpg |scale= 1:7,000,000 |location= Washington, DC |publisher= United States Geological Survey |oclc= 32889555 |access-date= November 7, 2013 |via= Wikimedia Commons |name-list-style= amp}}
In 1934, the swing bridge was replaced by a two-lane bascule bridge.{{cite news |last1=Crankshaw |first1=Joe |title=Archives: FIGG inspected Roosevelt Bridge and designed collapsed FIU bridge |url=https://www.tcpalm.com/story/news/local/2020/06/17/roosevelt-bridge-history-construction-and-impact-stuart-st-lucie/3205762001/ |access-date=8 May 2024 |agency=TC Palm |date=17 June 2020}} The original swing bridge was then dismantled but its swing span was reused a year later for the Torry Island Swing Bridge near Belle Glade, where it still operates today.{{cite news |last1=Luckhardt |first1=Greg E. |last2=Luckhardt |first2=Alice L. |title=Historical Vignettes: Martin County bridges and bridge tenders |url=https://archive.tcpalm.com/news/historical-vignettes--martin-county-bridges-and-bridge-tenders-ep-306449407-342336761.html |access-date=1 May 2024 |agency=TCPalm |date=14 October 2013}} The bridge was named Roosevelt Bridge after President Franklin D. Roosevelt, whose New Deal funded the bridge's construction.

A second two-lane bascule bridge (the one operating today) was built in 1964 right next to the 1934 bridge in an effort to widen the river crossing to four lanes. The newer bridge would carry northbound traffic, while the 1934 bridge would carry southbound traffic.
When the new high-level Roosevelt Bridge was completed in 1996, US 1 was rerouted over the new span. After the new bridge opened, the Old Roosevelt Bridge remained in service for local traffic and was reduced to two lanes on the 1964 bascule bridge. The 1934 bridge, which had operated for over 60 years, was then demolished. Although a small part of the 1934 span still stands abandoned on the north side of the river.{{Google maps |url=https://www.google.com/maps/@27.2032203,-80.2608232,3a,75y,348.27h,86.85t/data=!3m6!1e1!3m4!1si4xXrorDnHaCUTfP8OzUhQ!2e0!7i16384!8i8192?entry=ttu |title=Old Roosevelt Bridge |accessdate=May 7, 2024}}
Although the rest of the old Dixie Highway adjacent to the bridge has been given to the city of Stuart, the Florida Department of Transportation continues to maintain the bridge as unsigned State Road 707.{{citation needed|date=October 2014}}
