The primary route combines Interstates 85, 26, 40, 75, and 94. From Greenville, head north on I-85 to Spartanburg, then take I-26 west to Asheville. After Asheville, merge onto I-40 west to Knoxville, then I-75 north through Kentucky and Ohio. Near Toledo, take I-94 east toward Detroit and continue to Port Huron. Road quality is excellent on most interstates, but construction zones are common in Ohio and Michigan.

• Fuel stations are abundant every 20–30 miles on interstates, but prices vary widely. Fill up in South Carolina where taxes are lower; avoid filling in Tennessee or Ohio if possible.
• Rest areas are located roughly every 50 miles along I-75 in Kentucky and Ohio. Many have modern facilities and picnic tables.
• Tolls: No major toll roads on this route except possible tolls near Detroit (I-94). Have cash or a pass ready.

Fatigue management is critical on a 700-mile drive. Plan to stop every 2 hours or 150 miles. Safe rest zones include the Tennessee Welcome Center near Jellico and the Ohio Service Plaza near Cincinnati. For pet owners, many rest areas have designated pet relief areas. The route is generally safe, but watch for deer in rural sections, especially at dawn and dusk.
