Widen Turnpike (SR 91) PD&E

About the Project

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 from Jupiter (Indiantown Road) to Okeechobee Road (SR 70), in Palm Beach, Martin and St. Lucie Counties. The project consists of widening Florida’s Turnpike (SR 91) within the project limits by adding general toll lanes and/or express lanes in each direction.

FTE identified the need to widen this portion of Florida’s Turnpike 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.

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.

Study background

Florida’s Turnpike is a north–south toll road that runs approximately 313 miles through 11 counties in the Florida peninsula. Florida’s Turnpike System is used daily by more than two million customers.

This section of Florida’s Turnpike (SR 91) is currently a four-lane (two lanes in each direction) limited access facility. 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).

The proposed corridor improvements will bring many 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) to Okeechobee Road (SR 70) in Palm Beach, Martin, and St. Lucie Counties. The total project length is approximately 37 miles (see project location map below).

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.

The project development process begins with the high-level planning of a project through design and ultimately construction. This study is in the Project Development and Environment, or PD&E, Phase. As part of this effort, the corridor’s existing conditions and future traffic needs for the year 2045 are assessed. With this information, a concept would be developed to meet the 2045 design year transportation needs. The environmental and engineering analyses will be performed for this study. 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 to the public the recommended concept for feedback. Comments from the Public Hearing would be considered, and the study will be finalized.

The future of transportation is already here. FTE is leading the region by planning for a safer, more efficient, and more technologically advanced corridor for the future. Emerging transportation technologies will be considered in the PD&E study to address the transportation goals and needs along the corridor.

The PD&E study will identify corridor improvements that will:

reduce congestion create mobility choices improve safety enhance evacuation routes

[innovation bulleted text can be replaced with icons and text]

We are also identifying potential solutions that embrace emerging transportation technologies. As we look to integrate all these project goals into the overall design, a key element of the project will be consideration for new, emerging transportation technologies. There are several technologies that can be accommodated in a new corridor to help improve safety, create efficiency, and minimize environmental impacts.

The PD&E study began in spring 2017 and is anticipated to be completed by spring 2019. Over the next several months, FTE will begin the engineering and environmental analysis and identification of viable alternatives within the project limits. These viable alternatives will be presented at a future Alternatives Public Information Meeting.


It is anticipated that an Alternatives Public Meeting will be held at the beginning of 2019 (at two separate locations near the north and south project limits to accommodate interested stakeholders throughout the corridor). A Public Hearing will be held in early 2019 (at two separate locations).
