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

Motorists and residents of Central Florida already know a lot about the I-4 Ultimate reconstruction project. But an even larger project, called I-4 Beyond the Ultimate, remains relatively unknown — even as it gets underway.

I-4 Beyond the Ultimate is just what it says. It goes well beyond the current I-4 Ultimate work. I-4 Beyond the Ultimate will add 20 miles of extra lanes and reconfigured interchanges to the western end of the I-4 Ultimate project. And it will add another 20 miles of new lanes to the eastern end as well.

Both improvement projects are overseen by the Florida Department of Transportation and both add extra lanes, more bridges and improved interchanges. Most importantly, both improve the safety and mobility of the interstate while increasing connectivity between Central Florida communities.



  • 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
  • Adding dynamically tolled Express Lanes. Lanes are an option for those who want to avoid slower traffic and pay tolls that rise and fall with congestion.
  • Maintains the current six non-tolled lanes (three in each direction)


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. One segment, at least, is expected to start construction in late 2019.

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 eastern endpoint of the managed lanes another 20 miles 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, and both projects will maintain the current six non-tolled lanes while adding dynamic tolled Express Lanes. 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 some of the segments moving closer to construction so that residents and motorists can reap these benefits.”

While state and federal funding has been designated for several sections, the area closest to a construction date is Segment 2, which is a 3.5-mile section that runs between Beachline Expressway (State Road 528) and Kirkman Road (S.R. 435). That work may start in late 2019.

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-ofway 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.

The project also includes dynamically tolled Express Lanes through the 60 miles of improved interstate while maintaining the current number of non-tolled, general use lanes. 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.
