RIVERDALE — A semitrailer hauling livestock tipped onto its side Monday morning, killing many of the animals and causing an I-84 on-ramp to close for several hours.
The crash occurred around 10 a.m. on a curved on-ramp to the interstate in Riverdale, the Utah Highway Patrol said.
"That particular (on-ramp) is well-marked for traffic to slow for the gradual left turn for the merge onto I-84," the agency said in a statement. "The driver of the cattle truck was traveling too fast to safely negotiate the overpass and ran into the right hand side of the structure."
"Many cattle" were killed when the semitrailer tipped over, according to the statement. UHP Sgt. Todd Royce said he was unsure exactly how many of the animals died. Other livestock were injured and some were unhurt, he said.
The trailer was fully loaded and the live cargo weighed about 63,000 pounds, according to Royce.
The I-84 on-ramp was closed from 10 a.m. until early Monday evening. All lanes except one were closed on southbound I-15, which runs partially under the ramp, until around 1:30 p.m. The trailer came to rest partly over the guardrail and was a possible hazard for motorists driving below on I-15, Royce said.
The sergeant said the on-ramp was closed for so long partly because of the difficulty of removing all of the animals from the scene.
"Whenever we have a semi turn over, it’s pretty difficult," Royce said. "It just makes it that much more difficult when it’s live animals."
