Project Gears Eye Candy
The project will provide two (2) additional lanes in each direction of I-75 within the existing median for a distance of approximately 1.6 miles between the SR 80 interchange and the SR 78 interchange in Lee County, Florida. The project includes the widening of four (4) pairs of bridges and is surrounded by environmentally sensitive wetlands, navigable waterways, creeks and marsh.
At the heart of the project is the widening of the 3,900 foot I-75 over Caloosahatchee River Bridges.
These bridges are high-level fixed structures over a major navigable waterway and require heavy
construction activities within an environmentally sensitive area, including protection of manatees
and small tooth sawfish habitat. Use of special top-down construction methods are required as
well as close coordination with various regulatory agencies regarding impacts to wetlands and
threatened species. Construction is on-going.
