Knoxville to Orange Beach Road Trip: Gulf Coast Guide

Driving from Knoxville, TN to Orange Beach, AL means descending from the Appalachian foothills to the sugar-white sands of the Gulf Coast. The route covers about 460 miles via I-75 S, I-24 W, I-59 S, and I-10 E, then south on AL-59. The drive normally takes 7 to 7.5 hours without traffic. The highest point along the route is the Cumberland Plateau near Chattanooga, but by the time you reach Mobile Bay, you’ll be at sea level.

This road trip is worth it for the dramatic landscape shift alone. The Tennessee River Gorge near Chattanooga gives way to the flat coastal plains of Alabama. One curious detail: the interstate system here was partly built on old Native American trading paths, and near Tuscaloosa you can still see remnants of the old Federal Road.
