AMERICAN FORK, Utah (ABC4) — Southbound lanes on I-15 in American Fork turned into a parking lot on Monday morning, Nov. 13, after a fatal car crash near 500 East.

According to Sgt. Cameron Roden with Utah Highway Patrol, two cars were involved in the crash. UDOT traffic cameras after the incident show cars parked bumper-to-bumper along the interstate shortly after.

Roden confirmed with ABC4 that a passenger car crashed into the right barrier. Someone from the car got out of the car, walked in front of traffic and was hit. Roden said investigators are working to determine why the victim crossed into traffic.

A passenger from the first car left the scene, however, troopers reportedly were able to locate them and are talking to them. There were no injuries reported from the second car involved.

Roden confirmed all southbound lanes were closed with the exception of the HOV Express Lane for several hours. During the closure, commuters were encouraged to take an alternate route, such as US-89 while troopers investigated the crash and cleared the scene.

All lanes have since reopened and traffic is flowing as normal.
