Morning semi-truck crash ties up traffic on northbound Highway 99

FRESNO, Calif. (KFSN) -- Traffic is flowing smoothly again after a semi-truck crashed in West Central Fresno, tying up traffic on the 99 north for about an hour.

It happened just before 9 a.m. when the truck hauling cattle hit the back of another semi careening into two other vehicles.

No one was hurt but it took quite some time to clear up the mess.

It's not known what caused the driver carrying the cattle to lose control of his truck.
