As part of the largest design-build effort the state has ever taken on, Wi-Skies designed the entire lighting and electrical ITS work for the interchange, which comprised of several hundred devices.

This interchange is the busiest and fastest-growing interchange in the Atlanta area, subject to traffic volumes of over 250,000 vehicles daily. The overall design intent is to provide collector-distributor (CD) lanes throughout the project limits for a total of 8.3 miles along both SR 400 and I-285, which will eliminate much of the congestion in the area due to a poor existing interchange layout.
Throughout the design process, several lighting and ITS design alternatives were designed and considered.
