Indian Rocks Causeway

The Indian Rocks Causeway is a dual-span bascule bridge with two independently operating sections that cross the Narrows section of the Gulf Intracoastal Waterway. The eastern traffic lane uses the older span while the western lane is served by the newer span.

The original construction as a swing bridge began in 1916 and shaped traffic patterns for decades. The eastern span was rebuilt in 1958 and the western span was not completed until 1999.

The causeway functions as a daily link for residents and visitors traveling between the beach community and the mainland. Both groups rely on it equally to move between these two areas.

Crossing is free and straightforward for vehicles with no tolls required. Sailboats and other vessels can request bridge openings by calling on VHF Channel 09 or using horn signals.

Visitors often overlook that the two spans operate completely independently from each other and display different construction eras side by side. Looking closely at the structure reveals how the newer section mirrors the older one yet was built using modern techniques.
