I-4 Ultimate Improvement Project

The largest infrastructure project in Florida history is about to break ground.


I-4UltimateProjectLogoConstruction on I-4 Ultimate is scheduled to begin in early 2015. The project will rebuild 21 miles of I-4 from west of Kirkman Road in Orange County to east of State Road (SR) 434 in Seminole County, add two new dynamic tolled Express Lanes in each direction, replace more than 140 bridges, reconfigure 15 major interchanges, reconstruct the entire existing roadway and increase the posted speed to 55 mph.

The project is expected to be complete in 2021, meaning the backbone of transportation in Central Florida will be under construction for six and a half years.
