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.
