Construction began in fall 2023 and reached completion in March 2025

SEMINOLE COUNTY, Fla. – The Florida Department of Transportation (FDOT) has completed improvements at the Interstate 4 (I-4) and U.S.17-92 interchange in Seminole County. Designed to improve safety and enhance traffic flow, this milestone brings a smoother and safer driving experience to residents and visitors near the Central Florida Zoo and Botanical Gardens and downtown Sanford.

These improvements include the realignment of the eastbound I-4 exit ramp to U.S. 17-92, pedestrian safety enhancements at the eastbound I-4 exit ramp, and new auxiliary lanes and turn-lanes on Monroe Road and U.S. 17-92.

Construction crews realigned the eastbound I-4 exit ramp to westbound U.S. 17-92 to improve sight distance and create space for crosswalk improvements, including a pedestrian-activated hybrid beacon signal. This technology helps pedestrians cross the intersection more safely using flashing yellow-to-red lights to alert motorists to slow down and stop.

Additionally, two right-turn lanes from eastbound U.S. 17-92 to southbound Monroe Road were added, replacing the previous free-flow right turn. This improvement, along with reducing the speed limit from 50 mph to 35 mph, provides calmer traffic flow and safer pedestrian crossing.

Other improvements include:

• A new auxiliary lane on eastbound U.S. 17-92 between the westbound I-4 exit ramp and Monroe Road
• A new right-turn lane from southbound U.S. 17-92/Monroe Road to the eastbound I-4 entrance ramp
• A new left-turn lane from westbound Seminole Boulevard to southbound U.S. 17-92/Monroe Road

Construction teams also completed milling and resurfacing throughout the project limits, providing a smoother ride and extending the lifespan of the roadway. Fresh striping on U.S. 17-92 and the I-4 ramps provides better visibility for motorists and pedestrians, improving safety and efficiency at this interchange.
