The American Transportation Research Institute released its annual list highlighting the most congested bottlenecks for trucks in the U.S., including nine in Tennessee.

The 2018 Top Truck Bottleneck List assesses the level of truck-oriented congestion at 300 locations on the national highway system. The analysis is based on truck GPS data from more than 800,000 heavy duty trucks. The locations detailed in the list represent the top 100 congested locations.

“Tennessee’s large manufacturing base and continued job growth make trucks a lynchpin of the state’s economy,” says Dave Manning, TCW, Inc. president. “As such, reducing congestion in these freight bottlenecks was included in the Governor’s IMPROVE Act last year and now, 30 percent of those projects designated in that legislation are underway. ATRI’s analysis continues to allow us to target state and federal resources to keep trucks, and the economy, moving.
