General I-4 Beyond the Ultimate Toolkit
<< View All Toolkits

The I-4 Beyond the Ultimate projects are reconstructing and improving 40 miles of Interstate 4, 20 miles north of the I-4 Ultimate project into Volusia County and 20 miles to the south into Polk County.

I-4 Beyond the Ultimate is taking a phased approach to construction, working interchange by interchange as need dictates and funding allows. Various innovations will be implemented as part of the I-4 Beyond the Ultimate including Diverging Diamond Interchanges, Echelon Interchanges, Diamond Interchange U-Turns and managed lanes.



  • Two 20-mile sections on either end of I-4 Ultimate
  • Eastern end runs from S.R. 434 in Seminole County to S.R. 472 in Volusia County
  • Western end runs from Kirkman Road in Orange County to U.S. 27 in Polk County

Work Includes:

  • 129 rebuilt, new or widened bridges
  • 55 new drainage ponds
  • 22 interchanges improved or significantly rebuilt


I-4 Beyond the Ultimate: Building a Path to the Future

By now, most of Central Florida probably has heard of the I-4 Ultimate project. But another project called I-4 Beyond the Ultimate may seem completely new to many residents and motorists. However, this 40-mile project, which will become better known during the next few months, actually has been in development for several years and is currently in the beginning phases of construction.

For the average driver, who is not yet familiar with I-4 Beyond the Ultimate, it might be easiest to think of I-4 Beyond as an extension of the massive I-4 Ultimate Project. I-4 Beyond 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 current I-4 Ultimate project.

Both I-4 Beyond the Ultimate and I-4 Ultimate will improve pavement, ramps and interchanges. The Florida Department of Transportation (FDOT) oversees both projects.

“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.”

Interim projects in Seminole County are completed. 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.

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

The I-4 Beyond the Ultimate project is divided into six design segments. Each must undergo a stringent, multi-step process that includes planning, environmental study, preliminary design, right-of-way considerations, design and construction. While the sections stand at different points in the overall process, the Development and Environment (PD&E) Reevaluation Study has been finalized for the entire project.

I-4 Beyond the Ultimate: The Future of Interstate 4

Major reconstruction and improvement projects will transform 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) is overseeing both the 21-mile I-4 Ultimate project and the 40-mile I-4 Beyond the Ultimate project.

I-4 Ultimate, which is already well underway, 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 extends the western end of the I-4 Ultimate project from Kirkman Road in Orange County to U.S. 27 in Polk County — a distance of about 20 miles. It also extends the eastern end another 20 miles 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.
