SOUTH SALT LAKE — Drivers heading north on Interstate 15 in the South Salt Lake area experienced major delays after a truck and trailer caught fire on the freeway Saturday afternoon, forcing all northbound lanes to close temporarily.
Utah Highway Patrol officials initially said a semitrailer tipped over and caught fire around 4:20 p.m. However, witnesses and footage from the scene showed a pickup truck that was hauling a trailer.
The cause of the crash is under investigation, but UHP said they believe it could have been a mechanical issue.

The driver did not suffer any major injuries, and no other vehicles were involved.
All northbound lanes were closed until about 4:45 p.m. when one was reopened, then another around 5:45. All lanes were back open by around 7 p.m.
