- Construction starts mid-to-late fall 2026 and will take about four years at a cost exceeding $600 million, as part of the Moving Florida Forward initiative.
- Drivers gain more reliable travel times, reduced congestion, improved safety, and better hurricane evacuation capacity on this key Naples–Fort Myers corridor.
The Florida Department of Transportation (FDOT) is advancing a critical 21-mile widening of I-75 from north of Golden Gate Parkway (exit 105) in Collier County to south of Alico Road (exit 128) in Lee County. This stretch serves the growing corridor between the Naples/Golden Gate area and Fort Myers. Part of the state’s Moving Florida Forward Infrastructure Initiative, the project aims to boost capacity, improve traffic flow, and enhance safety amid rapid population growth in Southwest Florida. 1
Planned I-75 Improvements
Improvements include adding express lanes—two in each direction from Golden Gate Parkway to Corkscrew Road and one through the Corkscrew interchange—plus new auxiliary lanes throughout and accelerated congestion-relief lanes between Immokalee Road and Bonita Beach Road.
A new diverging diamond interchange will be built at Immokalee Road, with ramp modifications at key exits, full resurfacing, direct express-lane access at Vanderbilt Beach Road, and roughly 16 miles of noise walls in qualifying locations. These upgrades address current congestion while preparing the corridor for future demand. 2
Timeline, Investment, and Benefits
Construction is set to begin in mid-to-late fall 2026 and is expected to take approximately four years.
The investment exceeds $600 million. Drivers will gain more reliable travel times, reduced congestion, improved safety, and better hurricane evacuation capacity on this vital freight and commuter route. 3
Community Engagement
Recent public meetings in August and September 2026 gathered input on noise and traffic. A public hearing is planned for late 2026. FDOT continues refining designs based on community feedback to minimize impacts while delivering long-term mobility benefits for residents and visitors.
