FDOT
Florida • United States of America
The Florida Department of Transportation (FDOT) oversees one of the nation's most extensive highway systems with over 12,000 centerline miles serving the largest state east of the Mississippi. Key freight corridors include I-4, I-10, I-75, I-95, Florida's Turnpike, and SR-528. FDOT plays a vital role in supporting Florida's significant agricultural, automotive, and port-driven freight economy. The department operates a comprehensive permitting system for oversize and overweight vehicles and manages SunPass commercial vehicle transponders. The FL511 system serves truckers with live traffic and construction updates across all seven FDOT districts.
