BLUFFDALE, Utah — Slick roads, new snowfall, and vehicles traveling too fast for winter driving conditions combined to cause a multi-car accident and fuel spill Wednesday night on I-15. The accidents shut down northbound traffic for nearly 12 hours.
The Utah Highway Patrol announced at about 4:45 p.m. Thursday that all lanes on northbound I-15 at 14600 South were back open.

The UHP said an Amazon truck had jackknifed on northbound I-15, and then a passenger car entered the freeway near 14600 South and merged to avoid the jackknifed semi.
Next, a pickup truck traveling faster than the passenger car hit the back of the car. Finally, a semi-truck pulling two tankers filled with crude oil was also traveling too fast for the conditions hit the back of the Amazon semi.

“This semi that was hauling this oil overturned its rear trailer which compromised the trailer, and [oil] leaked out onto the highway,” UHP Sgt. Cameron Roden told Utah’s Noon News.
Roden originally said that nearly 1,500 gallons of crude oil spilled, and two lanes were blocked when the semi’s back tanker flipped and became detached.
Complicated cleanup
The number of vehicles along with the hazmat spill meant that cleanup of this accident wouldn’t be easy.
“There are a lot of things we need to do to handle the situation properly as far as the right departments,” Roden said. Those include the health department, environmental agencies, UDOT, and the Utah Highway Patrol.
Not to mention mopping up, removing, and disposing of more than 2,000 gallons of oil that spilled.
