Between fog, freezing rain, avalanches and snow, Utah Highway Patrol troopers in Utah County had more than their hands full all day Sunday and Monday morning.
Dispatchers reported more than 100 incidents involving rollovers, collisions and cars sliding off the highway between Lehi and Springville because of freezing rain and snow early Sunday night. However, despite the high property damage toll, no serious injuries were reported.And two separate multivehicle collisions - one involving seven vehicles near the Provo Center Street exit on northbound I-15 and another involving a dozen vehicles near the Orem 1200 North exit on southbound I-15 - caused stop-and-go traffic on the highway during rush hour Monday morning.
Dense fog and icy roads may have contributed to both incidents, dispatchers said. At press time, it was uncertain whether there were any serious injuries from those incidents.
Troopers are advising drivers to use caution while driving in adverse conditions and say most of the accidents Sunday were caused because drivers were either traveling too fast for conditions or were not using caution.
Portions of U.S. 189 near Deer Creek Reservoir were closed Sunday afternoon after a small avalanche nearly hit one vehicle and partially spilled onto the highway.
Both sides of the highway were closed between 4 and 6 p.m. while Utah Department of Transportation crews cleared snow and debris from the road surface, UHP trooper T.J. Kennedy said.
Unlike the much larger slide that closed the highway in Provo Canyon for much of the morning Wednesday - and which also destroyed much of the Bridal Veil Falls resort and briefly forced evacuations from the Springdell subdivision - there was no damage to any buildings. The Deer Creek slide was close to areas where crews were trying to trigger controlled avalanches earlier in the week.
Only one lane of U.S. 189 was closed after an even smaller slide happened near the Sundance Resort an hour later.
Additionally, U-92 in American Fork Canyon remained closed late Monday morning. UDOT officials closed that canyon twice last week but hoped to have it open sometime Monday afternoon.
A pair of small avalanches Thursday night and Friday morning forced officials to close the canyon, which had been closed while crews attempted to trigger controlled avalanches Wednesday morning.
UDOT officials say the possibility of other avalanches in both canyons, as well as Spanish Fork Canyon, is still high due to the heavy snowfall in the canyon last week.
