Sanibel Causeway, Road bridge connecting mainland Florida to Sanibel Island, United States.
The Sanibel Causeway extends 3 miles across San Carlos Bay with three two-lane bridge spans and two artificial islands between them.
The original causeway opened in 1963, replacing a ferry service that had operated since 1912, and underwent complete reconstruction from 2004 to 2007.
The construction of the Sanibel Causeway led to substantial population growth and the incorporation of Sanibel as Lee County's third city in 1974.
Vehicles traveling to Sanibel Island must pay a toll fee of $6, with three lanes processing more than three million vehicles annually.
The demolished sections of the original bridges were intentionally submerged to create artificial reefs in San Carlos Bay and the Gulf of Mexico.
