On Monday, January 12, 2026, at approximately 6:51 a.m., a flatbed commercial Mack truck was hauling construction supplies northbound on I-15, just north of the Brigham Road overpass, at Mile Post 4. The commercial truck dove off the freeway onto the soft shoulder in a curve. The vehicle continued driving on the shoulder towards the Brigham Road northbound on-ramp, which sits at a lower elevation. The commercial vehicle rolled over in the dirt gore between the on-ramp shoulder and I-15. The cab of the truck was crushed in the rollover, and the 66-year-old male driver received fatal injuries. St. George Fire responded to the scene to extricate the driver. Investigators are working to determine why the driver left the roadway.
