A sandstorm in Millard County caused multiple crashes on I-15 during the afternoon of July 25, leaving at least seven people dead and multiple others injured.

According to a press release from the Utah Highway Patrol, at least 20 vehicles were involved in the crash that occurred between Fillmore and Kanosh around 5 p.m. and closed both directions of the freeway.

First responders from Richfield and Beaver assisted with the crash, several people were transported to area hospitals in critical condition by both ground and air ambulances.

Northbound I-15 has partially reopened, but southbound I-15 will remain closed for several hours. UHP suggests southbound motorists exit at Meadow, exit 358, and take state Route 133 before re-entering the freeway at Kanosh.
