I-75 from East of SR 951 to SR 78, FDOT District One, Collier and Lee Counties, FL

Owner: FDOT District One Location: Collier and Lee Counties, Florida

---

This project involves a series of PD&E reevaluations to address an ultimate 10-lane configuration for 42 miles of I-75 from east of SR 951 in Collier County to SR 78 in Lee County. The project also includes highway, drainage, and major bridge design for limited-access facilities, express lane design, and coordination with the Florida’s Turnpike Enterprise (FTE) and Federal Highway Administration. The team will analyze and assess the project’s impact on the social, economic, cultural, natural, and physical environment. Key project elements include the determination of a Managed Lanes Typical Section Alternative, determination of Ingress and Egress locations, and determination of the project segmentation (phased implementation). Development of a corridor wide typical section and determination of the Express Lane versus General Use Lane buffer type (concrete barrier with full shoulders versus 4-foot buffer with Express Lane markers) will be a key geometric design consideration. The team will coordinate closely with FTE to evaluate the tolling concepts for both the final condition and each segment of the phased implementation to ensure tolling remains continuous and to minimize temporary infrastructure. KCA is providing environmental design services for this project.
