One woman died and seven people were injured in separate traffic accidents Tuesday.
In another incident, a Utah Highway Patrol trooper helped deliver a baby off north lanes of I-15 near Springville.
Brittany Brady, 19, Murray.
Brady was traveling southbound on I-15 near 800 North about 9:30 a.m. when she apparently lost control of her vehicle while switching lanes, said Utah Highway Patrol trooper Duane Hunt.
Brady's vehicle left several skid marks on the road before it crashed into the metal barricade in the median, flipped into the air and landed in northbound lanes, Hunt said.
Brady was ejected, and investigators believe she was killed instantly.
Four other vehicles in the northbound lanes also crashed as a result of the overturned vehicle. One man was taken by ambulance to a local hospital for a cut on his neck, and the freeway was shut down for three hours.
The cause of the accident was still under investigation late Tuesday.
In another accident, seven adults were sent to Pioneer Valley and Jordan Valley hospitals for minor injuries after an accident involving three cars at the intersection of 10400 South and Bangerter Highway that shut down all lanes of Bangerter for about 1 1/2 hours, South Jordan police officer Josh Whatcott said.
At about 4:30 p.m., a car travelling north on Bangeter collided with two cars travelling west on 10400 South. Police have not issued any citations, but are investigating whether a driver chatting on a cellular phone is responsible, Whatcott said.
Around 5:30 p.m., Zackary Mark Johnson was born inside a car parked off northbound I-15 near Springville with the help of Utah Highway Patrol trooper Sterling Clark and 911 dispatchers.
Shortly after Clark approached a maroon sedan with the mother, Kristina Johnson, reclining in the passenger's seat and father Ben Johnson outside the door on his knees, the baby's head began to show.
With his UHP-issued birthing kit, Clark guided the father, who also was on the phone with the dispatchers. "He just popped right out," Ben Johnson said.
Zackary weighs 6 pounds, 11 ounces. He is 18 1/2 inches long.
"Everything is perfect," Johnson said.
