By now, most of Central Florida probably has heard of the I-4 Beyond the Ultimate project. This 40-mile project has been delivering roadway improvements to some of Central Florida’s most heavily traveled areas.

It might be easiest to think of I-4 Beyond as an extension of the massive I-4 Ultimate Project, the largest highway infrastructure project in Florida history spanning 21 miles of Interstate 4 (I-4) from west of Kirkman Road (State Road (S.R.) 435) to east of S.R. 434. I-4 Beyond the Ultimate extends the improvements and innovation 20 miles past the eastern endpoint of I-4 Ultimate and also adds 20 miles to its western endpoint.

With a goal of improving safety, mobility and connectivity in Central Florida, the I-4 Beyond the Ultimate project is a complex undertaking that is expected to rebuild and improve 40 miles of I-4. When complete, it will cover twice the length of the I-4 Ultimate project.

“I-4 Beyond the Ultimate will bring improved safety and mobility to Central Florida and will help increase connectivity between communities,” said FDOT Senior Project Manager Beata Stys-Palasz, P.E. “We are very excited to see construction beginning so that residents and motorists can reap these benefits.”

Improvements in Seminole County are complete, including:

• Milling and resurfacing of eastbound I-4 from Lake Mary Boulevard to U.S. 17-92 at the Seminole-Volusia county line, milling and resurfacing of westbound I-4 from U.S. 17-92 to Lake Mary Boulevard, the addition of an eastbound I-4 auxiliary lane from the end of I-4 Ultimate to Lake Mary Boulevard, and the reconstruction of the E.E. Williamson Road overpass.

• The interchange improvement projects at I-4 and U.S. 17-92 and County Road (C.R.) 46A and Rinehart Road, both of which were completed in 2025.

In Orange county, the Daryl Carter Parkway overpass was converted into a diverging diamond interchange (DDI) in July 2025. This project transformed the existing I-4 overpass into an interchange with three new ramps. Drivers on both eastbound and westbound I-4 now have access to Daryl Carter Parkway from two new exit ramps, and motorists can also access eastbound I-4 right from Daryl Carter Parkway. FDOT completed this project in September 2025.

A project in Osceola County to reconfigure the I-4 and C.R. 532 interchange into a diverging diamond interchange began construction in July 2021 and was completed in early 2023.

I-4 Ultimate and I-4 Beyond the Ultimate, once complete, will have transformed 60 miles of Interstate 4 (I-4) into a signature corridor that improves safety and mobility and adds many aesthetic and landscaping touches to roadway.

The Florida Department of Transportation (FDOT) oversaw the 21-mile I-4 Ultimate project and now oversees the 40-mile I-4 Beyond the Ultimate project.

I-4 Ultimate, which reached completion in 2022, runs from west of the Kirkman Road interchange in Orange County to east of S.R. 434 in Seminole County.

I-4 Beyond the Ultimate picks up where the I-4 Ultimate project left off. The original design of I-4 Beyond the Ultimate included a complete reconstruction of I-4 from Kirkman Road in Orange County to U.S. 27 in Polk County — a distance of about 20 miles — and another 20 miles north of downtown Orlando from S.R. 434 in Seminole County to S.R. 472 in Volusia County.

Although there are multiple projects, they will link seamlessly to increase connectivity among Central Florida communities while supporting the economy and lifestyle of the region well into the future.
