Heavy rain closes roads, triggers flooding across Buncombe County and region

A 12-foot void beneath Charlotte Highway near the Henderson County line turned Tuesday’s rain into a transportation emergency across western North Carolina, with closures and washouts spreading into Buncombe County and neighboring counties as crews scrambled to assess damage.

828 News NOW reported that flooding, road closures and infrastructure damage spread through Henderson, Buncombe and Transylvania counties as the storm intensified. The National Weather Service said some mountain communities near Interstate 40 saw rain falling at two to three inches per hour, with storm totals reaching roughly three to six inches in some spots. Low-lying roads quickly became impassable, and transportation officials shut down routes as water and debris pushed through vulnerable areas.

The most dramatic failure reported so far was on Charlotte Highway, where crews found the deep void under the roadway near the Henderson County line. Separate reports also noted multiple closures in Gerton and Bat Cave, along with a new slope failure on Shumont Road near Lake Lure. Officials kept a flash-flood warning in effect for northeastern Henderson County because runoff and debris were still moving through problem spots even as the heaviest rain began to ease.

For Buncombe County, the danger is not just the storm itself but the way another round of heavy rain can instantly cut off access. Closures on mountain roads can slow emergency response, disrupt commutes and leave rural communities with longer detours or no clear route in or out. That risk has been magnified since Tropical Storm Helene hit in September 2024, bringing devastating flooding, landslides and damage across Buncombe County.

Buncombe County and its six municipal partners later developed a Helene Recovery Plan with 114 projects meant to rebuild housing, repair infrastructure, restore natural resources, strengthen disaster preparedness and improve long-term resilience. The county also opened a Helene Resource Center at 94 Coxe Avenue in Asheville in April 2025 to help with FEMA applications, disaster case management, hazard mitigation and private roads and bridges support.

That recovery work gives Tuesday’s flooding immediate weight. In a county still repairing roads, slopes and drainage systems after Helene, one hard burst of mountain rain can still trigger closures, threaten travel corridors and delay rebuilding across the region.
