The interchange where Interstate 75 meets Interstate 285 north of Atlanta, long known as the Cobb Cloverleaf, has been ranked the fifth most congested freight corridor in the country in the 2026 national bottleneck rankings. The Cobb County interchange sits near The Battery and carries heavy truck volumes alongside daily commuter traffic, producing delays that ripple across regional freight schedules.
Freight bottleneck rankings measure the average truck speeds and congestion at key highway junctions, and a high placement signals lost hours and higher operating costs for carriers moving goods through metro Atlanta. The Cobb interchange has appeared near the top of these lists in prior years, and its 2026 placement reflects continued growth in both freight and passenger demand on the corridor.
State investment is targeting parts of the regional network. The amended fiscal 2026 budget signed by Governor Brian Kemp in March directs more than 1.6 billion dollars to extend and add bidirectional express lanes on Interstate 75 in Henry County, 185 million dollars for interchange conversions on State Route 316, and 250 million dollars in local maintenance and improvement grants.
Georgia logistics leaders met at the Cobb Galleria in April for the Georgia Logistics Summit, where corridor congestion was among the topics. The state estimates roughly 5,000 logistics companies employ 110,000 Georgians and generate more than 50 billion dollars in annual sales, underscoring why freight throughput in Cobb County and surrounding areas carries economic weight.
