IVOR—A portion of Route 460 was closed for more than two hours Monday after the drivers of two tractor-trailers hit head-on near Ivor, Virginia State Police said.

One of the unidentified drivers was seriously injured and in stable condition at Sentara Norfolk General Hospital on Tuesday, said Sgt. Michelle Anaya. The other unidentified driver suffered minor injuries and was taken to Sentara Obici Hospital in Suffolk.

The driver of an empty tractor-trailer, who was seriously injured, was eastbound when his rig left the road and he overcorrected, police said. His truck crossed into the opposite lane, hitting the driver of a tractor-trailer, who was hauling slag, a by-product made during the smelting of metallic ore.

The truck hauling slag overturned, dumping about 400 gallons of diesel fuel, and oil, engine, transmission debris, Anaya said.

No one has been charged.
