A 4.8km causeway between Sanibel Island and mainland Florida has been “substantially completed” after being rendered unusable by Hurricane Ian in September 2022.
The work was carried out by a joint venture between de Moya Group and Superior Construction for the Florida Department of Transportation.
The department commented that the project was its first phased design-and-build contract. The work involved pile-driving, earthworks, drainage repair, concrete placement and asphalt laying.
The restored causeway contains resilience features such as steel-sheet pile wall systems and concrete caps and roadway barriers.
The project withstood three hurricanes in 2024: Debby, Helene and Milton.
Toby Mazzoni, Superior Construction’s project manager, said: “What makes this project special is that we’ve given this community infrastructure they can rely on through whatever comes next. We build for the long haul, especially when communities are counting on us most.”
Nick Largura, Superior’s chief executive, said: “Building five seawalls during the hurricane season, railing in high-quality armor stone materials from Alabama and Georgia quarries, and improving resilience, while collaborating with multiple stakeholders on a first-of-its-kind phased design-build contract, is a monumental feat. I’m incredibly proud of this team.”
