Mother Nature has brought travel to a halt in the Great Smoky Mountains, where a fresh round of torrential rain triggered both flooding and a rockslide, forcing the closure of a critical stretch of Interstate 40.
According to the Associated Press, the disruption occurred on Wednesday afternoon near mile marker 450 in eastern Tennessee, just shy of the North Carolina border. The Tennessee Department of Transportation shared updates on social media, confirming the incident.
Emergency crews were still clearing debris and draining floodwaters as of Thursday.
“No estimated reopening time has been provided,” transportation officials said.
This section of I-40 — spanning 12 miles across Tennessee and North Carolina — has already endured its share of punishment.
In late September, Hurricane Helene, which was a Category 4 storm upon making landfall in Perry, Florida, unleashed devastating floods that tore through the Pigeon River Gorge, badly damaging or wiping out large portions of the road.
By March, teams had managed to open a single, narrow lane in both directions, stabilized just enough for cautious travel. To allow vehicles trapped by the latest blockade to turn back, workers were forced to remove a several-inch-high curb separating the lanes.
According to the National Weather Service, approximately 2.5 to 3.5 inches of rain fell over just three hours.
A permanent solution remains years away. Engineers plan to drill steel rods deep into the bedrock beneath the highway, inject them with grout, and spray the cliff face with concrete — an intensive process intended to anchor the road in place for good.
Interstate 40 runs coast-to-coast from Wilmington, North Carolina, to Barstow, California. Skirting around the Great Smoky Mountain stretch isn’t easy; alternate routes can add dozens of miles. Trucks, in particular, face major hurdles.
Many become stranded on narrow, winding backroads, and commercial traffic is outright banned from U.S. 441 through Great Smoky Mountains National Park.
