Midway Road (County Road 712) Widening Projects

Home / About the Project

About the Project

The proposed project is currently in design and involves the widening and reconstruction of County Road (CR) 712 / Midway Road from a two-lane undivided roadway to a four-lane divided facility between Glades Cut Off Road / County Road 709 and Selvitz Road. The project also includes replacement of the existing bridge (ID 940050) over Florida’s Turnpike (SR-91). Midway Road is a major east-west road that connects residents and commuters to and from Interstate 95 (I-95) and to commercial areas along US Highway 1 (US 1).  The total project length is approximately 1.6 miles. The project ties into the existing four-lane section to the west of Glades Cut-Off Road to a four-lane segment east of Selvitz Road. The project corridor is in unincorporated St. Lucie County, but is the northern border to the City of Port St. Lucie.

The primary purpose for this project is to provide additional capacity to meet existing and future traffic needs, improve safety by alleviating existing roadway and capacity deficiencies, and allow opportunities for pedestrian, bicycle, and transit facilities. The additional capacity will also improve freight mobility and enhance emergency evacuation along the project corridor.

Midway Road has been identified in the St. Lucie County and Martin County 2045 Regional Long Range Transportation Plan as well as the St. Lucie Transportation Planning Organization (TPO) 2045 Cost Feasible Plan. The project is included in the State Transportation Improvement Program and the St. Lucie TPO Transportation Improvement Program.

We are pleased to announce that the Midway Road projects have been identified as a congestion relief project (number 18) under Governor DeSantis's Moving Florida Forward Infrastructure Initiative helping to secure and advance construction funding.

Proposed Improvements:

  • Widen the existing road from a 2-lane undivided facility to a 4-lane divided facility. The eastbound and westbound lanes will be separated by a raised landscaped median.
  • Left turn lanes will be provided in the median to allow access to adjacent side streets, properties and businesses.
  • Accommodate 7-foot buffered bike lanes on both sides of the roadway.
  • Construct a 12-foot bike/pedestrian path  along the south side of the project.
  • Construct a concrete box culvert on the south side of the project to replace the existing roadside ditch.
  • Install landscape along the south side of the project.
  • Replace the existing bridge over the Turnpike.
  • A new partial interchange with Florida's Turnpike will also be constructed.

Temporary Maintenance of Traffic:

  • Construction will be completed in phases to minimize interruption to traffic.
  • Construction activities will take place during daytime hours from Monday through Friday.
  • One lane in each direction on Midway Road will remain open at all times and local access will be maintained.

Community Participation

Community Awareness and input is a key component during the project design phase. A public workshop will be held once the project is funded for construction.  Notices will be sent prior to the public meeting. 

Project Development and Environment (PD&E) Study

The FDOT completed a Project Development and Environment (PD&E) Study prior to design to determine the environmental, social and economic impacts associated with the proposed transportation improvements. The PD&E was completed in 2017. The PD&E Documents can be found in the documents and publications section.
