Interstate 85 runs 668 miles from Montgomery, Alabama to Petersburg, Virginia, threading the Piedmont and serving as the spine of the southeastern US auto-manufacturing belt. The route connects the Mercedes plant in Tuscaloosa (via I-65 transfer), the Hyundai plant in Montgomery, the Kia plant in West Point, GA, the BMW plant in Spartanburg, SC, and the Honda, Toyota, Nissan, and Volvo facilities throughout the Carolinas.

For freight, I-85 is one of the most truck-dense corridors in the South — the Atlanta segment (concurrent with I-75) is among the most congested in the country, and the Charlotte segment (concurrent with I-77 briefly) handles enormous container drayage from the inland port at Greer, SC. The corridor connects directly to the Port of Charleston via I-26.

Geographically I-85 is mostly rolling Piedmont, with modest climbs through the southern Appalachian foothills around Anderson, SC and Greenville. Weather hazards are dominated by severe spring thunderstorms across the entire corridor, occasional ice events in the Carolinas, and chronic Atlanta congestion that ripples up and down the route.
