SALT LAKE COUNTY, Utah -- A man is in critical condition after a wrong-way driver struck his vehicle on eastbound Interstate 80 early Sunday morning, and the driver who struck that vehicle has been arrested for DUI.

The accident was reported at 3:02 a.m, and I-80 was closed at 2300 East as crews investigated.

The Utah Highway Patrol states a Nissan Versa was travelling north in the southbound lanes of the east belt of I-215 near 5500 South when the vehicle then entered eastbound I-80 while traveling westbound near Foothill Drive.

In the area of 2300 East, the wrong-way Nissan struck a Dodge van head-on in the left lane of I-80.

The driver of the Nissan, 34-year-old Eliza Vanorman of Bountiful, was wearing her seat belt and was taken to University of Utah Hospital in fair condition. She was later arrested for DUI.

"As we were speaking with the female driver, she had a strong odor of alcohol about her," said Sgt. Jacob Cox of the Utah Highway Patrol.

The driver of the Dodge van, a 21-year-old man from Salt Lake City, was taken to U of U Hospital in critical condition. UHP states: "He was not wearing his seat belt, which contributed to the severity of his injuries."

UHP provided audio from several 911 calls associated with the incident, including one from the injured man.

Caller: "My leg!"

Dispatcher: "Are you involved in the accident?

Caller: "Yes."

The call continues, with the dispatcher asking: "Is anyone pinned inside the vehicle?"

Caller: "No. Just me."

Dispatcher: "Just you in the vehicle. Are you pinned? Are you able to get out of your vehicle safely, or are you stuck?"

Caller: "No. My leg is broken."

Later in the call, the dispatcher asks: "What happened? Did a car come and hit you?

Caller: "Yes. A car was heading the wrong way on the freeway."

There were at least two other 911 calls reporting the wrong-way driver, with one caller stating: "I literally dodged it, barely."

Another caller reported the car was "going pretty fast", at about freeway speeds.

Sgt. Cox said it can be challenging to coordinate responding to a wrong-way driver.

"The trooper has to figure out where the wrong way driver is, which direction and then find the right way to get past that person in order to find the next place they can turn around to try and intersect the driver," he said. "We're not allowed to go the wrong way on the freeway, because it would cause more hazard."
