This project will expand Florida's Turnpike Mainline/SR 91, stretching from the West Palm Beach Service Plaza to just north of Southern Boulevard/SR 80/US 98, boosting the highway from four lanes to eight. The scope includes widening and resurfacing the pavement, upgrading or replacing bridges, enhancing drainage, and adding noise walls where applicable. Additionally, the Southern Boulevard/SR 80/US 98 interchange will see improvements to optimize traffic movement.
