North and southbound lanes of Interstate 15 have been closed at the southern Utah state line near Mesquite after a fatal crash involving multiple semi trucks and a passenger car, according to Nevada and Arizona Highway Patrols.
"The interstate is going to be blocked southbound for an extended period of time and motorists should avoid the area," said Sgt. Bottoms with AHP.
Arizona Highway Patrol routed all southbound traffic on I-15 onto Old Highway 91, where drivers can get back on the interstate in Mesquite.
The crash happened at approximately 5:23 p.m. when a semi truck veered off the road onto the shoulder of I-15 northbound, said Trooper Travis Smaka with Nevada Highway Patrol. Another semi was parked on the shoulder, and was struck by the semi that veered off the road.
After it hit the parked semi, the first truck crossed all the northbound lanes of the interstate and entered southbound traffic on the other side of the interstate. It hit a second semi that was traveling southbound, Smaka said, which then hit a passenger car also traveling southbound.
The southbound semi overturned, spilling its contents across the interstate, Smaka said.
The driver of the first semi truck was pronounced dead at the scene, according to Smaka. Both occupants of the passenger car were taken to hospitals in St. George. Their condition was unknown at the time of this report. The driver of the third semi had minor injuries but was released from the scene without being transported to a hospital. No other parties were injured.
Smaka estimated the closure of both directions of the interstate would remain in place for several hours Wednesday night.
