Project Description

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.

This project includes the design and reconstruction of the I-4 at SR 557 Interchange from an existing partial cloverleaf interchange configuration to a diamond interchange. Right-of-way has already been acquired for this project and no additional right-of-way is needed.
The intent of this 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. This project realigns the existing eastbound and westbound general use travel lanes 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 on SR 557 at the I-4 on-ramp and off-ramp terminals. 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 will be provided under I-4, east of the interchange, to facilitate the movement of wildlife between the north and south sides of I-4. Emergency stopping sites will be provided on both I-4 off-ramps to SR 557 and conventional roadway lighting will be provided along I-4 and SR 557.
If you are traveling westbound on I-4 and get off at Exit 48, make a right onto SR 557 to go north to unincorporated Polk County, or go three quarters around the roundabout, south over the bridge and through the second roundabout toward Lake Alfred/Winter Haven.
If you are traveling eastbound on I-4 and get off at Exit 48, make a right onto SR 557 to go south toward Lake Alfred/Winter Haven or go three quarters of the way around the roundabout, north over the bridge (Orange) and through the second roundabout to head to unincorporated Polk County.
If you are driving south along SR 557, you can continue through both roundabouts toward Lake Alfred/Winter Haven (purple line). To enter I-4 westbound, take the first roundabout to I-4 West toward Tampa (green line) or travel over the bridge (Orange) and go three quarters of the way around the second roundabout to take the I-4 East ramp toward Orlando (blue line).
If you are driving north along SR 557, you can continue through both roundabouts into unincorporated Polk County (purple line) or take the ramp before the first roundabout to I-4 East toward Orlando (green line). To head west on I-4 toward Tampa, you will travel over the bridge (orange) and go three quarters of the way around the second roundabout and take the I-4 West ramp toward Tampa (blue line).
The existing bridge will be demolished, and a new four-lane bridge (shown in orange) will be built over I-4.

A new divided median and roundabouts will improve safety for drivers by reducing the potential for crashes. The roundabouts provide full access to drivers exiting I-4 to go north toward unincorporated Polk County or south toward Lake Alfred/Winter Haven. The roundabouts will also provide full access to drivers traveling on State Road 557 wanting to take I-4 west toward Tampa or I-4 east toward Orlando.
