Upcoming Improvements on I-4 Will Keep Traffic Flowing in Seminole County

The Florida Department of Transportation (FDOT) is planning improvements to Interstate 4 (I-4) that will help keep traffic flowing smoothly and safely in Seminole County.

These improvements are tentatively scheduled to begin construction in mid to late 2019. The improvements include:

  • Adding an eastbound I-4 auxiliary lane from the end of the I-4 Ultimate project to Lake Mary Boulevard.
  • Reconstructing the E.E. Williamson Road overpass.
  • Resurfacing eastbound I-4 from the end of the I-4 Ultimate project to Lake Mary Boulevard, from Lake Mary Boulevard to County Road 46A, and from State Road 46 to the Volusia County line.

Resurfacing the eastbound I-4 lanes will extend the life of the roadway. Adding the auxiliary lane will accommodate traffic flow from the completed I-4 Ultimate project. To make room for the new auxiliary lane, the E.E. Williamson Road bridge over I-4 must be widened.

New Pedestrian Features Planned for E.E. Williamson Road

The Florida Department of Transportation (FDOT) is planning an improvement project that will reconstruct the E.E. Williamson Road overpass bridge on Interstate 4 (I-4) just north of the State Road 434 interchange. 

The new E.E. Williamson Road overpass bridge will include:

  • Wider eastbound and westbound traffic lanes
  • Six-foot bicycle lanes on the outside of both traffic lanes
  • Six-foot wide sidewalk on the eastbound side
  • 10-foot wide pedestrian trail on the westbound side that will extend another 1.2 miles east to Lake Emma Road

The rebuilt bridge will improve access to the Seminole Wekiva Trail for residents on the east side of I-4 who use E.E. Williamson Road to reach the trail entrance one-tenth of a mile west of the overpass bridge.  

Construction is scheduled to begin in mid to late 2019. To stay up-to-date on the construction timeline, visit i4Beyond.com/seminole.

What is I-4 Beyond the Ultimate?

I-4 Beyond the Ultimate may seem completely new to many residents and motorists. This 40 miles of Interstate 4 (I-4) improvements will become better known in the coming months, and has actually been in development for several years.

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 the Ultimate as an extension of the massive I-4 Ultimate project. I-4 Beyond the Ultimate will extend 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, I-4 Beyond the Ultimate 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.

“I-4 Beyond the Ultimate will bring improved safety and mobility to Central Florida and will help increase connectivity between communities,” said Florida Department of Transportation 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.”

I-4 Beyond the Ultimate is divided into six design segments. Each must undergo a strict, 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 Project Development and Environment (PD&E) Reevaluation Study has been finalized for the entire project.
