Southbound Interstate 15 near 2700 North were closed for hours following a crash that happened around 8:40 a.m. Friday.
According to Utah Highway Patrol, a Jeep Wrangler was traveling southbound on the onramp to merge onto I-15 southbound near 2700 North. The Jeep then struck a Ford Explorer in front of it before crossing into the gore area where it was struck by a semi-truck.
The gore area is the area near on and off-ramps where white lines form a triangle. Vehicles are not allowed in these areas unless they are disabled or are an authorized emergency vehicle.
The semi then veered left striking a Kia Optima forcing that vehicle over the concrete wall and rolling it into one of the lanes of northbound traffic.
The driver of the Jeep was not wearing a seat-belt and sustained critical injuries. She was flown to a hospital where she is undergoing treatment currently. All other occupants involved in the crash suffered only minor injuries.
All of Southbound I-15 reopened by 10:30 a.m. Friday.
