To provide motorists with immediate congestion relief, FDOT is prioritizing the construction of two new congestion relief lanes along 7.5 miles of Interstate 4 (I-4) from east of U.S. 27 and east of World Drive. Construction is scheduled to begin in early 2025, and the congestion relief lanes will open by the end of 2025. The new lanes will be located on the inside of the existing mainlines to provide motorists with congestion relief.

After those lanes are open, additional work in the Accelerated Start phase will add the pavement to expand I-4 to the full width for 10 total lanes at two interchanges: ChampionsGate Boulevard and World Drive. By expanding these sections earlier in the project timeline, better allows FDOT to prepare for the adjoining I-4 projects and build them simultaneously.
