A driver who accidentally dumped his entire load of gravel on I-15 shut down southbound lanes in Juab County for nearly an hour.

Just after 1 p.m., a driver was nearing mile post 237 when he accidentally pushed the wrong button, said Utah Highway Patrol Trooper Cameron Roden.

"The driver made a statement to our sergeant that he might have accidentally hit the switch to his belly dump and lost his entire load in the right lane," Roden said.

The man was carrying two belly dumpers, but only one lost its load, Roden said. The driver was cited for spilling his load.

UHP officers talking over police radio described the gravel as 10 inches thick for several hundred feet.

A front loader and a sweeper truck were brought in to clean up the gravel, putting as much as they could back into the belly dumpers, Roden said.

Cars had to wait while the road was cleaned. It finally opened around 2 p.m., Roden said. There were no other accidents due to the gravel.
