Florida’s Turnpike Enterprise, part of the Florida Department of Transportation (FDOT), is conducting a Project Development and Environment (PD&E) Study for the widening of Florida’s Turnpike Mainline (SR 91) from north of SR 60 to south of Clay Whaley Road, in Osceola County.

Project Development Process Graphic

The PD&E Study is the second phase of the FDOT project development process. Each PD&E Study requires the combined efforts of professional engineers, planners and scientists, who collect and analyze project-related information to determine social, economic, physical and environmental impacts. Afterward, they develop the best solution for a community’s transportation needs.

Noise Studies will be performed as part of this PD&E study. During the Design Phase, final noise wall locations will be determined.

Project Background

Florida’s Turnpike Enterprise has identified the need to widen this portion of Florida’s Turnpike Mainline (SR 91) to add capacity that will accommodate future traffic volumes of freight and passenger vehicles linked to the projected growth in population and industry. Additionally, Florida’s Turnpike Mainline is a designated emergency evacuation route by the Florida Division of Emergency Management.

The PD&E Study involves evaluating alternatives for widening Florida’s Turnpike Mainline (SR 91) from north of SR 60 to south of Clay Whaley Road (Mile Post 193-238.5) in Osceola County, Florida. Possible future interchange access locations are also included as part of this study. The Turnpike Mainline within the project area is currently a four-lane (two lanes in each direction) limited-access toll facility. The PD&E Study will evaluate and prepare project cost for:

  • Widening the Turnpike Mainline to three general toll lanes in each direction, from north of SR 60 to the planned Southport Connector Expressway
  • Widening the Turnpike to four general toll lanes in each direction, from the planned Southport Connector Expressway to south of Clay Whaley Road
  • Recommendations for potential phased implementation
  • Prepare alternatives for consideration of up to two new interchanges
  • No build alternative

The proposed corridor improvements will bring additional benefits such as:

  • Increasing capacity
  • Meeting existing and future travel demands
  • Improving facility operations
  • Enhancing roadside safety features

Study Area

The project limits are along Florida’s Turnpike Mainline (SR 91) from north of SR 60 (Yeehaw Junction – Mile Post 193) to south of Clay Whaley Road (St. Cloud – Mile Post 238.5) in Osceola County, Florida. The total project length is approximately 45.5 miles.


This PD&E study will examine existing environmental conditions across the Social, Cultural, Natural and Physical Environments so that we can analyze the potential impacts of various improvement alternatives. The project area ranges from agricultural and conservation lands to the south and more populated areas to the north, including potential future developments. Cultural resource surveys have not covered the entire project area and additional surveys will be conducted. There are multiple recorded archaeological sites and resource groups along the corridor that require documentation and evaluation in a Cultural Resources Assessment Survey Report. Within the Natural Environment, there is potential involvement of multiple protected species and their habitats, wetlands, and surface waters. The project crosses the Three Lakes Wildlife Management Area, crosses two water management districts (WMD) (St. John’s River WMD and South Florida WMD), spans multiple drainage basins, and is adjacent to the C-34 Canal. There are sensitive noise receptors on the northern part of the corridor due to the development occurring in the area. Potential contaminated sites will be investigated during the study, particularly near agricultural areas.

A State Environmental Impact Report (SEIR) will be prepared for this project.


The Enterprise is at the forefront of planning for a safer, more efficient, and technologically advanced transportation system for the future. The Enterprise continually seeks opportunities to integrate emerging transportation technologies that can help reduce congestion, create mobility choices, minimize environmental impacts, and improve safety. The Enterprise also recognizes that connected and automated vehicle (CAV) technologies hold unprecedented opportunities for enhancing mobility and increasing safety on our roadways.
