Virginia State Police say a tractor-trailer carrying 4,600 gallons of milk overturned and spilled some of its load in the Richmond area.

Troopers told media outlets that the spill occurred Monday afternoon on a ramp leading from a road to Interstate 295 in the suburb of Glen Allen. Police say the truck driver was taken to a hospital with injuries, but those weren't considered life-threatening.

Authorities say the ramp had to be closed for about two hours while crews cleaned up the spilled milk. It wasn't immediately clear how much milk had spilled.

Police say the investigation continues into what caused the truck to overturn.
