by Stephanie CrosbyThe interchange of interstates 64, 65 and 71 in downtown Louisville is one of the worst in the country – that’s according to a new study out today from the American Transportation Research Institute and the Federal Highway Administration. It ranks Spaghetti Junction as the 11th-worst bottleneck in the nation.The report measured the average speeds at which a vehicle can navigate the interchange during peak and non-peak hours.Chuck Moore is the president of Eagle Steel, which operates in Indiana and Kentucky. He says the bottleneck creates a logistics problem for his company and others.“If you didn’t have you company in Louisville or the greater Louisville area, you probably wouldn’t bring it to town with the bottleneck that we have," says Moore. "We depend on the highways to get product from Indiana to Kentucky. We sometimes just stand still on the bridge that is there, and the roads around because of that bottleneck.”Moore is also the co-chair of the Greater Louisville Manufacturing and Logistics Network – a group that supports the Ohio River Bridges Project.Other interchanges that ranked higher than Louisville on the list include three in Chicago, and others in New Jersey, Lox Angeles, St. Louis and Atlanta.
