State Road 528 Airport Plaza Conversion

Widening a Heavily Used Roadway
Orange County, Florida

The State Road (SR) 528 airport toll plaza conversion project consisted of widening two miles of the existing high-speed, limited-access facility and replacing the mainline toll plaza with a new split-plaza configuration, equipped with both cash and electronic toll collection (ETC) only express lanes. The existing mainline plaza was located just outside the north entrance to the Orlando International Airport, and the proximity to the airport coupled with the heavy volume of airport traffic was creating operational issues on the SR 528 mainline as well as the airport access ramps. A split-plaza configuration was designed for the replacement due to the required width of the proposed plazas, to accommodate both the ETC express and cash lanes, and the limited right-of-way available.

The SR 528 eastbound mainline plaza is now located on an embankment just east of the Conway Road bridge, and the westbound mainline toll plaza was reconstructed at the current location of the existing mainline toll plaza. A ramp plaza is located on the eastbound entrance ramp to SR 528 from Conway Road. A segment of the existing frontage road was reconstructed to accommodate placement of the westbound mainline toll plaza. The SR 528 eastbound off-ramp to Conway Road and the SR 436 SB on-ramp to westbound SR 528 were reconstructed to provide adequate merge distances.
