The journey from Nashville, Tennessee to Myrtle Beach, South Carolina spans approximately 500 miles (800 kilometers) by road. Under normal conditions, expect 7.5–8.5 hours of driving time.
I-40 East → I-26 East → I-95 South → US-501 South is the standard routing:
I-24 East → I-75 South → I-26 East (via Chattanooga/Atlanta) is longer (~560 miles) but avoids Smoky Mountain grades and winter weather risks.
Traffic hotspots: Knoxville (I-40/I-75 merge), Asheville (I-40/I-26), Spartanburg (I-85/I-26), Florence (I-95/US-501). Summer weekends add 1–2 hours near Myrtle Beach.
Scenic detour: Blue Ridge Parkway from Asheville adds beauty but 2+ hours. Worth it in October.
Fuel, food, and rest stops are plentiful. Fill up before entering the mountains; services thin on I-26 through the Pisgah/Nantahala forests.
