The primary goal is to tackle congestion at a notorious commercial and passenger traffic bottleneck, Dale said. The stretch of interstate handles freight coming to Atlanta from the Port of Savannah. With the recent expansion of the Panama Canal and deepening of the harbor in Savannah, the port plans to double its capacity in the next 10 years. Cargo transportation is therefore expected to grow.

Atlanta had the eighth-worst traffic congestion in the world last year, according to Inrix, a transportation analytics firm. Drivers spent nearly 20 percent of their driving time in traffic during peak hours. It also has two of the top 10 truck traffic bottlenecks nationally.

This I-75 corridor is already past capacity, so instead of just building another lane, the state’s transportation department has opted for a more innovative approach, Dale said. The agency expects the lanes to reduce delays by 40 percent in 2030.
