The Design-Build Team is in the process of replacing the existing partial cloverleaf interchange with a new diamond configuration. The new interchange is 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.
The intent of the project is to prepare the median along I-4 to accommodate the future I-4 Master Plan (Ultimate) improvements with provisions for special purpose (express) lanes and a high-speed rail (HSR) corridor. The existing eastbound and westbound general use travel lanes will be moved to the outside to coincide with the I-4 Ultimate alignment.
SR 557 will be widened to 4-travel lanes, two in each direction within the limits of the state's limited access right-of-way, with roadway transitions to the existing two-lane County Road, (CR 557) north and south of the interchange.
Dual teardrop shaped roundabouts will be provided access to and from SR 557 at the I-4 on and off-ramps. The existing two-lane bridge over I-4 will be demolished and replaced with a new four lane bridge that accommodates the necessary horizontal and vertical clearances over the I-4 Ultimate corridor.
A new wildlife crossing constructed under the interstate and located east of the interchange will allow wildlife to safely cross between the north and south sides of I-4. Emergency stopping sites will also be provided on both the I-4 off-ramps to SR 557 and conventional lighting will be provided along I-4 and SR 557.
A public hearing was held on Thursday, October 23, 2020 to present proposed access changes on SR 557 south of Interstate 4.

Burkhart, P.E., at (813) 402-4150 or by e-mail at Doug.Burkhart@dot.state.fl.us.
