Late on August 1, 2025, heavy rains hit Great Smoky Mountains National Park. As a result, Walker Camp Prong swelled and triggered a landslide.
The result? Roughly 100 feet of the southbound lane between mile markers 12 and 13 on the Tennessee side of the park was undercut. The rain event prompted a full closure of Newfound Gap Road until further notice.
What now?
NPS engineers and Federal Highway crews are conducting structural integrity tests and designing repairs. As of Saturday’s news release, no firm reopening date has been announced. The park anticipates a partial reopening on the North Carolina side (from Oconaluftee up to Newfound Gap) early in the coming week to restore access to Clingmans Dome.
What RVers should expect
If your RVing plans include the Great Smoky Mountains National Park, here’s what you need to know:
• There is a full closure of US 441/Newfound Gap Road between Mile 12 (just south of Alum Cave Trailhead) and the state line.
• No traffic is allowed between Gatlinburg, TN, and Cherokee, NC, via the park’s central corridor.
• Detours may involve significant additional mileage and elevation changes. Plan your fuel and provision needs accordingly.
• Weight and clearance restrictions on parkways (e.g., Foothills Parkway) make them less suitable for large rigs.
Alternate routes for RVers
Officials have given their primary recommendation advising travelers to use the Interstate 40 Corridor. From the Gatlinburg area, take US 441/Great Smoky Mountains Parkway back to I-40 (Exit 435 at Sevierville). Head east on I-40 to Asheville, NC (Exit 53), then connect to US 23/US 441 toward Cherokee.
Interstate standards guarantee adequate lane width, gentle grades, and clearances suitable for trailers and motorhomes. This route will safely take you around the closure.
As a second option (with caution advised) you can take US 321 and Foothills Parkway from Gatlinburg. Use the Gatlinburg Bypass (US 441 Bypass) north of town, then connect to US 321 south through Townsend. From Townsend, continue on US 321 to Maryville, where you can rejoin I-40. Please note that some of the Foothills Parkway segments have steep grades and narrow shoulders. Check tow-vehicle capabilities and local road advisories before proceeding.
As a third option, if the Blue Ridge Parkway is open and your RV size isn’t a deterrent, from Asheville, you can jump onto the Blue Ridge Parkway southbound to Cherokee. Please note that although quite scenic, the Parkway often imposes vehicle-length limits and has steep, winding sections. You should verify any current closures and vehicle restrictions on the NPS website before taking this route.
Tips for a smooth detour
Here are some actions you can take to make a detour safer and smoother:
• Check current conditions: Always review the Great Smoky Mountains National Park “Current Conditions” page for real-time alerts and reopening updates.
• Plan fuel stops: Gas stations are sparse inside the park. Plan to fill your tank in Gatlinburg, Townsend, or along I-40.
• Allow extra time: Detours can add 1–2 hours to your trip, depending on traffic and weather.
• Stay connected: Follow the park’s social media feeds (Facebook, X) for on-the-fly updates and road-status photos.

Thank you for the news, Gail, and for the clear directions for alternate routes into the Smokies. Have a great day and safe travels!
Please note that the Interstate 40 alternative takes you through the part of I-40 near the NC/TN border that is down to 1 lane in each direction for the foreseeable future due to Hurricane Helene damage to the roadway. May be slow going through this area.
