Florida’s Turnpike Enterprise (FTE), part of the Florida Department of Transportation (FDOT), is conducting a Project Development and Environment (PD&E) study for Florida’s Turnpike (SR 91) Widening from Jupiter (Indiantown Road/SR 706) to Ft. Pierce (Okeechobee Road/SR 70), in Palm Beach, Martin and St. Lucie Counties. The project consists of widening Florida’s Turnpike within the project limits by adding general toll lanes.

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 are performed in the PD&E phase and the Design phase, and re-evaluated if there is a major change in design to the roadway.

Project Background

FTE identified the need to widen this portion of Florida’s Turnpike (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 for the year 2045. Florida’s Turnpike is also a major evacuation route for Southeast Florida.

This section of Florida’s Turnpike (SR 91) is currently a four lanes (two lanes in each direction). Existing interchanges within the study corridor include SW Martin Highway (SR 714), Becker Road, Port St. Lucie Boulevard (SR 716), and Okeechobee Road (SR 70). Numerous bridge structures will need to be widened or reconstructed along with the roadway. The project corridor includes crossings of the Loxahatchee River and St. Lucie Canal. Potential reconfiguration of existing interchanges and new interchange access locations will also be considered as part of the PD&E study. It is anticipated at this time that a majority of the improvements will stay within the existing right of way.

The proposed corridor improvements will bring additional benefits to the community such as:

  • reduced congestion
  • enhanced mobility options for longer trips
  • improved evacuation and emergency response times


This can be accomplished with a focus on avoiding and minimizing social, physical and environmental impacts.


This PD&E study will evaluate capacity and interchange improvements that will include:

  • new limited access (toll) lanes
  • modifications to existing interchanges
  • new interchange locations

Study Area

The project limits are from Jupiter (Indiantown Road/SR 706) to Ft. Pierce (Okeechobee Road/SR 70) in Palm Beach, Martin, and St. Lucie Counties. The total project length is approximately 37 miles.

This PD&E study will be conducted in order to identify and evaluate any potential environmental impacts that may result from widening this section of Florida’s Turnpike. The study includes engineering services to develop concept plans that will be used to consider all social, economic, and environmental effects, and potential mitigation measures as required by the FDOT PD&E Manual, along with the required environmental documents, engineering reports, and public involvement activities.

A State Environmental Impact Report (SEIR) is the expected level of environmental documentation required for this project.


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

If you have an idea for a technology or innovation that you would like to be considered as part of this study, please reach out to one of the contacts in the Stay Connected section below.


As part of the PD&E study, concepts will be developed and refined to meet the 2045 design year transportation needs. The concepts would be presented at an Alternatives Public Information Meeting for the public to provide feedback. The project team would review the feedback and refine the concepts. A Public Hearing would then be scheduled to present the recommended concepts to the public for feedback. Comments from the Public Hearing would be considered and the study will be finalized.

Schedule is subject to change.
