Gatlinburg to Cambridge: Smokies to Chesapeake Road Trip

The route from Gatlinburg, TN to Cambridge, MD traverses over 600 miles, crossing the Appalachian Mountains, the Shenandoah Valley, and the Delmarva Peninsula. A little-known fact: the final stretch crosses the Chesapeake Bay Bridge, one of the world's longest over-water steel structures at 4.3 miles. This drive typically takes 9–10 hours of pure driving time, but full-day explorations reward with rich history and diverse landscapes.
