Interstate 15 was reduced to a single lane just north of Leeds for nearly five hours after a loaded semitractor-trailer overturned and slid down an embankment during heavy rains Wednesday afternoon. Shortly before 4 p.m., officers and emergency personnel responded to a rollover on southbound I-15 near mile marker 29 just north of Leeds involving a semitractor-trailer that went off the roadway, Utah Highway Patrol Sgt. Joe Pastor told St. George News Thursday. The semi was hauling a load of fencing materials when the crash took place. Troopers arrived to find the semi down an embankment to the right of the roadway. The 44-year-old driver from Illinois was reportedly uninjured in the crash.
