Interstate 71 runs 345 miles from Louisville, Kentucky to Cleveland, Ohio, serving as the primary northeast diagonal across Kentucky and Ohio. It connects three of the four major Ohio metro areas (Cincinnati, Columbus, Cleveland) along with Louisville and the Kentucky Bluegrass region. Despite its modest length, I-71 carries among the highest truck volumes per mile of any Ohio interstate, particularly the Columbus-Cleveland segment.
For freight, I-71 is the spine of intra-Ohio commerce, tying the Cincinnati and Louisville logistics hubs to the Columbus distribution centers and the Cleveland industrial belt. Auto-parts traffic feeding the Honda plants in Marysville and the Ford plant in Brook Park makes up a significant share of the truck volume.
Geographically I-71 is mostly rolling, with no major climbs. The route crosses the Ohio River at Louisville on the Kennedy / Lincoln bridges (jointly with I-65) and again uses the Brent Spence Bridge corridor at Cincinnati. Weather hazards are dominated by lake-effect snow at the Cleveland terminus, occasional ice events in central Ohio, and severe weather across Kentucky in spring.
