This project will convert the Sand Lake Road and I-4 interchange into a Diverging Diamond Interchange (DDI). Unlike a conventional interchange, the lanes in a DDI cross over to the left side of the roadway at a traffic signal. That limits the number of traffic signal phases and allows drivers to make left turns without crossing oncoming traffic. The lanes then change back to the right side of the road at another traffic signal.  These improvements will help to accommodate future projected traffic demand and improve driver safety and efficiency.

In a variation of the typical DDI design, the reconfigured interchange will include a new loop ramp from westbound Sand Lake Road to Turkey Lake Road. Motorists traveling westbound on Sand Lake Road who want to access Turkey Lake Road south of the interchange will no longer turn left across traffic. Instead, they will enter the loop ramp on the right and pass over Sand Lake Road. At the end of the ramp, they can choose to travel north or south on Turkey Lake Road.

Construction began Spring 2023 and is anticipated to reach completion in Early 2027. This project is being constructed in conjunction with FPID No. 444315-3, the combined construction cost is $219,342,910.12
