The Florida Department of Transportation (FDOT) has begun a Project Development and Environment (PD&E) study to consider proposed improvements on Interstate 75 (I-75) (State Road 93A) in Hillsborough County. A map detailing the limits of the project is shown below. This project (shaded green on the map) extends approximately 15.5 miles from south of US 301 to north of Fletcher Avenue. I-75 passes through the communities of Tampa, Temple Terrace, Brandon, Mango, and Palm River-Clair Mel. The primary land use along the corridor is suburban residential with some scattered commercial areas.

Study Purpose and Need
The purpose for this project is to provide a higher capacity and a safer facility to better meet the future transportation demand in the rapidly developing areas of Hillsborough County. I-75 is part of the Florida Intrastate Highway System (FIHS) and the Strategic Intermodal System (SIS). Preserving the operational integrity and regional functionality of I-75 is critical to mobility in this region. Future traffic demand along this stretch of I-75 is anticipated to increase by about 50 percent by the year 2025. This anticipated traffic growth and high levels of congestion create a need to analyze the corridor for necessary improvements to ensure it continues to operate efficiently and safely. This corridor is also designated as an emergency evacuation route.

Proposed Improvements
The FDOT is conducting this PD&E study to improve the operational capacity of I-75. Currently I-75 is a six-lane limited access facility. Proposed Build Alternative improvements could include addition of travel lanes and/or Special Use Lanes (SUL) in each direction and interchange enhancements. SUL’s may include several options for maximizing the corridor’s capacity, such as High Occupancy Vehicle (HOV) lanes, transit ways or access/service roads. The PD&E study will also consider the No-Build Alternative. The appropriate improvement to be employed will be evaluated and determined in the Project Development phase.
