An 18-wheeler and two pickups hit and killed 17 cows Thursday morning when the herd of cattle got loose from a pasture and wandered onto La. 30 in St. Gabriel, Iberville Parish Sheriff’s Office Maj. Johnny Blanchard said.

The incident has caused the closure of La. 30 in St. Gabriel until authorities can upright the 18-wheeler which overturned in a ditch after hitting the cows, Blanchard said.

The road will be temporarily opened for school traffic, Blanchard said, but will close again until the 18-wheeler can be removed.

The incident occurred around 2 a.m.

The driver of the 18-wheeler was taken to a local hospital for treatment of his injuries.

Most of the cows had been rounded up by 6:30 a.m., Blanchard said.

The incident occurred in front of the St. Gabriel Police Department, Blanchard said.
