The Florida Department of Transportation (FDOT) is transforming the Interstate 4 (I-4) and County Road (C.R.) 532 interchange near ChampionsGate into a diverging diamond interchange (DDI). This innovative interchange is designed to improve safety and mobility in the area. A new traffic pattern began at the interchange on Sunday, July 10. Motorists approaching the interchange on C.R. 532 switch to the left side of the road at a traffic signal. After passing under the interstate, they return to the right side at another traffic signal.
With the DDI traffic pattern in effect, motorists no longer turn left across the opposing lane at any point in the interchange. In addition, the number of signal phases has been reduced from four to two, which provides more efficient traffic movement through the DDI. Conflict points — locations in the interchange where vehicles’ paths merge, diverge, or cross — have been reduced by more than half.
Although the DDI is in place, work will continue at the interchange to add bicycle and pedestrian features — there is currently no pedestrian access through the interchange. Intelligent transportation system (ITS) technology, signage, signalization, curbs, and landscaping will also be installed during the remainder of this project, and the roadway will be milled and resurfaced.
