Roan Mountain: NC 261 and TN 143 over Carvers Gap
NC 261 and TN 143 combine into one continuous 25-mile route over Roan Mountain, meeting at Carvers Gap (5,500 ft) where the state line and the Appalachian Trail cross the road. Very curvy on both sides of the gap, through Cherokee National Forest and Roan Mountain State Park.

Planning the drive
NC 261 and TN 143 are two different state highways that function as one continuous drive, meeting at Carvers Gap (5,500 ft, matched almost exactly by our own measured high point of 5,509 ft), where the Appalachian Trail itself crosses the road. 87 counted bends and 18 switchbacks over 25.4 miles at an 8.0% maximum grade make this genuinely technical on both sides of the gap, not just a connector between two towns. Wikipedia: North Carolina Highway 261
Carvers Gap sits high enough to see real winter weather well before it arrives in the surrounding valleys, and this route runs through Cherokee National Forest and Roan Mountain State Park for most of its length — remote enough that a closure or a problem isn't quickly reached by help. Check current Tennessee and North Carolina road conditions before a cold-season trip.
