Lake Monroe Bridge, Road bridge remains in Sanford, Florida, United States

Lake Monroe Bridge is a steel road bridge spanning the St. Johns River in central Florida, connecting Seminole and Volusia Counties. The structure features a Warren through truss design and crosses approximately 627 feet of water.

The Lake Monroe Bridge was built between 1932 and 1933 to replace a wooden bridge that was manually operated and tolled until 1926. Its Warren truss swing span was fabricated by Ingall's Iron Works of Birmingham, Alabama, with swing gear from Earle Gear and Machine Company of Philadelphia, and erected by W.W. White of St. Petersburg. Construction gave work relief during the Great Depression. Historical markers claim it was Florida's first electrically operated swing bridge.

The bridge transformation from a vital transportation link to a fishing pier reflects the evolution of infrastructure and community needs in central Florida.

The bridge is located at Lake Monroe Wayside Park and offers access to fishing opportunities along the water below. The site is easy to reach and good for a quick stop.

The swing span turned on gearing supplied by the Earle Gear and Machine Company of Philadelphia, while the truss itself was fabricated by Ingall's Iron Works of Birmingham, Alabama, and erected by W.W. White of St. Petersburg. Historical markers at the site credit it as Florida's first electrically operated swing bridge.
