About the Study

St. Lucie County is conducting a Project Development & Environment (PD&E) Study to widen and reconstruct the existing 10-mile segment of Glades Cut Off Road/County Road (CR) 709 from Range Line Road to Selvitz Road in St. Lucie County. As part of the study, all intersections within the project limits will be evaluated.

The PD&E study is the second phase of the project development process. Each PD&E study requires the combined efforts of professional engineers, planners, and scientists, to collect data, develop and evaluate alternatives, conduct studies, prepare reports, and gather input from the public, applicable agencies, and interested parties. The goal of the PD&E process is to develop the best solution which meets the transportation needs and offers the greatest benefit with the least impact.

Key considerations for the study include:

  • Enhance safety
  • Increase capacity along Glades Cut Off Road to accommodate future 2045 traffic volumes
  • Enhance multimodal mobility
  • Evaluate intersections for potential signalization
  • Minimize impacts to environmental resources
  • Address planning consistency with the St. Lucie Transportation Planning Organization (TPO)
  • Coordinate with local stakeholders (HOA’s, schools, etc.) and the public


A noise study will be performed as part of this PD&E study to determine the locations potential noise barriers are needed. During the Design Phase, final noise barrier locations, if warranted, will be determined.
