The truck was carrying a minimum of 12 275-gallon totes of a cleaning agent, the state Division of Environmental Protection Agency said. A contractor cleaned up the spill. Dead fish were observed along nearby Paint Creek, the DEP said in a statement.

Turnpike director Jeff Miller said the truck’s driver was arrested on a drunken driving charge, WCHS-TV reported.

A detour had been set up, including one that took drivers far north on Interstate 79 and from the south on U.S. Route 19 through Summersville.
