Blackburn Point Bridge, Historic swing road bridge in Osprey, Florida.
Blackburn Point Bridge is a road bridge in Osprey, Florida, built as a metal Warren pony truss spanning the Gulf Intracoastal Waterway. At its center, a pivot mechanism allows the entire span to rotate horizontally so that boats can move through the waterway beneath.
The bridge was built in 1926 by the Champion Bridge Company, based in Wilmington, Ohio, as one of the first road links between the Florida mainland and Casey Key. It was later added to the National Register of Historic Places, recognizing its place in the early development of Florida's coastal road network.
The bridge connects the mainland to Casey Key and is used daily by people who live on the island or visit its beaches. When the span swings open for passing boats, drivers wait briefly at the signals, giving a clear sense of how waterway and road traffic share the same crossing point.
The bridge carries two-way traffic and is open to all vehicles, but drivers should expect short stops when the swing span opens for boats on the waterway. Crossing in the early morning or late afternoon gives the best chance of a smooth passage and a clear view of the surrounding water.
The metal truss of this bridge has cone-shaped rivet heads that were rarely used in pony truss designs of the 1920s, and they are still visible if you look closely at the structure. This small detail was a hallmark of the Champion Bridge Company's approach to construction.
