A tractor-trailer hauling calcium hypochlorite, a chemical used to clean swimming pools, overturned on Interstate 26 East in Polk County, North Carolina, on Monday afternoon, October 26, spilling part of its load and closing the eastbound lanes for hours, the North Carolina State Highway Patrol said. The driver was cited for failure to maintain lane control.

The crash happened near mile marker 59, close to the Polk-Henderson county line, on the mountain section of I-26 between Asheville and the South Carolina line. Troopers said the truck's load shifted when the driver failed to maintain lane control, and the shifting load caused the vehicle to overturn. Early television reports placed the scene in Henderson County; the Highway Patrol's later account, reported Tuesday, put the overturn in Polk County near the county line.
What the truck was carrying
The trailer was carrying calcium hypochlorite, a strong oxidising chemical widely used to disinfect swimming-pool water. Because the load is classed as a hazardous material, the spill could not be handled as a routine tow job: the Asheville Fire Department's hazardous materials team responded to the scene, contained the spill and cleaned the roadway before the wrecked truck could be removed, according to the reports.
Officials said the incident posed no threat to the public or the environment. No injuries were described in the reports available on Tuesday, and the driver's name has not been released.
Impact on drivers on a key mountain freight route
Interstate 26 is one of the main freight corridors through the Blue Ridge Mountains, linking Asheville with Hendersonville, Spartanburg and the South Carolina Lowcountry, and connecting with Interstates 40 and 85. A full eastbound closure on the mountain grade therefore backs up long-haul trucks as well as mountain commuters, and there are few parallel routes for heavy vehicles on that stretch. The eastbound lanes stayed shut for hours while crews removed the truck and finished the cleanup, WLOS reported.
For the many Punjabi and South Asian truckers who run Southeast freight lanes, the stretch of I-26 over the Polk-Henderson grade is a familiar one: steep, winding and unforgiving of a shifting load. Troopers' finding in this case — a load that moved after the driver lost lane control — is the sequence safety officials warn about most on mountain grades, where a high centre of gravity leaves a driver almost no room to recover once a trailer starts to go over.
A tractor-trailer's cargo is secured on the assumption the truck stays upright and in its lane. Once a heavy load moves sideways on a grade, the trailer's weight works against the driver. That is why patrol reports list lane control and load movement together in overturn investigations like this one.
What happens next
The Highway Patrol's citation for failure to maintain lane control is the only enforcement action reported so far, and the case now follows the normal North Carolina traffic-court process for the unnamed driver. The reports did not announce any wider investigation, any charge connected to the hazardous load itself, or any change to traffic arrangements on that section of I-26, which reopened after the cleanup was completed.
