In September 2022, Hurricane Ian devasted the lifeline between the Sanibel Island and mainland Florida. After $328 million, the Superior-de Moya Joint Venture team have announced the restoration project of the Sanibel Causeway has been completed. The work re-establishes and fortifies the critical 3-mile stretch.
The rebuilt causeway now features dramatically enhanced storm resilience, including:
- Steel sheet pile wall systems: Nearly 750,000 sq. ft. (26,200,750 lbs.), including a king pile wall system, with lengths varying from 20 to 70 ft.
- Concrete caps: Approximately 19,750 linear feet total (4,930 ft. of retaining wall concrete caps; 8,460 ft. of island wall concrete caps; and 6,360 ft. of sea wall concrete caps)
- 127,996 tons of strategically placed armor stone
- Elevated seawalls from 5 to 8 ft.
- Advanced stormwater drainage systems throughout the causeway
- 19,500 tons of asphalt pavement placed
- Innovative scour prevention system utilizing 25,225 square yards of gabion marine mattress; 79,000 tons of coastal rip rap and bedding stone
- 6,900 linear feet of various permanent roadway concrete barriers
- 25,000 square feet of fractured fin concrete fascia
“What makes this project special is that we’ve given this community infrastructure they can rely on through whatever comes next,” said Toby Mazzoni, Project Manager at Superior Construction. “We build for the long haul, especially when communities are counting on us most.”
