Two females in a white car headed northbound on I-15 near mile post 261 and for some unknown reason hit the right wall and then the left wall causing a disruptions in traffic.
In an attempt to avoid hitting the small car, a semi over corrected and tipped over blocking all, but one lane of traffic.
The driver of the semi was not hurt. The two women in the car were transported to Utah Valley Medical Center with minor injuries.
The semi was carrying copy machines.
