Around 1:45 p.m. on Monday, two vehicles were involved in a head-on collision on SR-73, closing the road between Eagle Mountain Blvd and Airport Rd. for more than one hour.

The accident occurred when one driver, headed westbound on SR-73, allegedly attempted to pass a dump truck in a no-passing zone and collided with an eastbound driver, according to the Utah County Sheriff’s Office.

“Both drivers are in serious condition and were taken by ambulance to local hospitals,” said UCSO Sergeant Spencer Cannon in a tweet, announcing the crash.

Cannon, along with other officers of the Utah County Sheriff’s Office, were already nearby at the Cory B. Wride Memorial, honoring Wride on the 9th anniversary of his death.

Some deputies heard the crash happen, according to the USCO.

Law enforcement officers were quickly on the scene to assist while those involved in the crash waited for medical personnel to arrive.

By 3 p.m., both eastbound and westbound lanes of SR-73 were re-opened to vehicle traffic.
