PSL wants a new I-95 interchange at Marshall Parkway to fix SW traffic
With southwest Port St. Lucie booming, the city is pushing a new Marshall Parkway interchange on I-95 to relieve the overloaded Gatlin and Becker Road exits.
If you've sat in traffic at the Gatlin Boulevard or Becker Road I-95 interchanges lately, the city hears you. At its February 18, 2026 Winter Workshop, the Port St. Lucie City Council reaffirmed a set of road priorities aimed at easing congestion in fast-growing southwest PSL.
The headline item is a proposed new Marshall Parkway interchange at I-95, which FDOT plans to study starting in fiscal year 2026–27. The goal is to take pressure off the existing Gatlin and Becker interchanges, which are increasingly maxed out.
Other priorities include completing the Hegener Drive / Paar Drive corridor out to Range Line Road — filling in the road grid in an area that's exploded.
The context is staggering: southwest PSL has added more than 100,000 residents since 2010. In response, the council adopted policies requiring developers to dedicate land for roads and build key infrastructure earlier in the process.
Roads are the perennial sore spot of fast-growing Florida cities, and PSL is no exception. A new interchange would be years away — but at least it's officially on the radar.
