Project Description

This Design-Build project replaced the existing partial cloverleaf interchange with a new diamond configuration with dual teardrop shaped roundabouts at the entrance and exit ramps of the interchange. These changes are designed to improve traffic circulation and enhance safety, emergency access, and truck access in Polk County, Florida. The project is located at Exit 48 along the I-4 corridor. Traffic started using the new bridges on January 13, 2023.

The new bridges and road are higher and wider to accommodate the future I-4 Master Plan (Ultimate) improvements with provisions for special purpose (express) lanes and a high-speed rail (HSR) corridor. Existing eastbound and westbound general-use travel lanes were moved to the outside to coincide with the I-4 Ultimate alignment. CR 557 was widened to four travel lanes, two in each direction within the limits of the state's right-of-way. Other improvements include emergency stopping locations on both the I-4 off-ramps to CR 557, and new conventional lighting along I-4 and CR 557.

Additionally, a new wildlife crossing under the interstate just east of the interchange was constructed allowing wildlife to safely cross between the north and south sides of I-4. For 50 years animals on either side of I-4 have been separated. The addition of the wildlife crossing is significant in providing safe passage for animals to access protected lands on both sides of the intestate, while also protecting drivers from crashes that may otherwise occur when animals attempt to cross the roadway.

Ribbon Cutting

On Wednesday, June 5, the Florida Department of Transportation (FDOT) held a ribbon-cutting ceremony to celebrate the completion of the Interstate 4 (I-4) at County Road (C.R.) 557 interchange and a new wildlife crossing in the Hilochee Wildlife Management Area.

“I’m thankful for the leadership of Governor DeSantis and support of the Florida Legislature who share FDOT’s vision to modernize Florida’s infrastructure to meet the unique characteristics and future needs of each community in Florida,” said FDOT Secretary Jared W. Perdue, P.E. “This new interchange and wildlife crossing will reduce congestion, enhance safety, and creates a new wildlife connection to allow Florida’s diverse wildlife a safer way to traverse the Hilochee Wildlife Management Area.”

“The successful completion of this project is a testament to our commitment to innovation and community well-being,” said FDOT District One Secretary L.K. Nandam. “By incorporating state-of-the-art design and environmental considerations, we are paving the way for a more connected future.”
