Construction crews are moving forward on Seminole County projects with work beginning on the U.S. 17-92 and County Road (C.R.) 46A interchanges along Interstate 4 (I-4) last month. These new construction projects are part of the I-4 Beyond the Ultimate program, which is improving Central Florida’s transportation infrastructure.

Construction on the U.S. 17-92 improvements began October 9. Crews are progressing in clearing, grubbing, and excavation work, with the end goal of realigning U.S. 17-92 at I-4. The eastbound I-4 exit ramp will be realigned to westbound U.S. 17-92 to allow for crosswalk improvements, which include a pedestrian-activated crosswalk signal. Additionally, eastbound U.S. 17-92 will have an auxiliary lane added between the westbound I-4 exit ramp and Monroe Road. Southbound U.S. 17-92/Monroe Road will have a right turn lane added to connect to the eastbound I-4 entrance ramp, and a westbound left turn lane will be added from Seminole Boulevard to drive south on U.S. 17-92/Monroe Road. The U.S. 17-92 plan will improve sight distance for motorists, upgrade crosswalks, and reduce the speed limit from 50 mph to 35 mph to enhance safety in the area.

The estimated timeline for completion of this project is late 2024.

Seminole County travelers will also see drastic changes to the intersection at C.R. 46A and Rinehart Road near I-4. The enhancements will increase capacity at the intersection by modifying select existing turn lanes and adding new turn lanes. The eastbound through/right turn lane on C.R. 46A will be converted to a through-only lane, and two turn-only lanes will be added — for a total of three — to southbound Rinehart Road. A third lane will also be added to southbound Rinehart Road between C.R. 46A and Timacuan Boulevard and existing left turn lanes will be extended.

Construction on this phase of the Seminole County improvements began October 29. Crews have started clearing and grubbing work on the east side of C.R. 46A. Completion of the C.R. 46A project is scheduled for 2025.

Over the past several years, Central Florida has attracted residents and visitors in unprecedented numbers, which has led to increased demand on state roadways. In particular, the number of motorists driving within the I-4 corridor has continued to grow.

Motorists are advised to remain alert and use caution when driving through work zones. Always follow the posted speed limit and avoid distractions to ensure the construction crews can safely complete their tasks.
