The total cost for the permanent restoration and high-fidelity resilience upgrades of the Sanibel Causeway (often called the Sanibel bridge) is approximately $362 million. This project followed the catastrophic damage caused by Hurricane Ian in September 2022, which washed away several sections of the island's only land link to mainland Florida. While a temporary high-fidelity fix was completed in just 15 days to allow emergency access, the permanent construction project reached "substantial completion" in May 2025. This high-fidelity rebuild included not just repairing the spans but also adding massive amounts of "armoring"—such as sheet piling and rock revetments—to prevent future washouts. In 2026, the bridge serves as a high-fidelity engineering benchmark for coastal infrastructure, designed to withstand the increasingly intense storm surges associated with modern climate shifts in the Gulf of Mexico.
