A Utah highway made the naughty list of many commuters when all northbound lanes were temporary closed due to the road being covered in coal.
The Utah Department of Transportation said a truck hauling coal lost its load before 9 a.m. Wednesday morning on Interstate 15 at the Pioneer Crossing in American Fork.
Traffic camera footage from the scene shows all northbound lanes closed while crews worked to clean the coal from the road.
A single lane of traffic was opened a short time after 9:15 a.m. and traffic had returned to normal by 10:20 a.m.
Investigators did not say what caused the truck to dump its load.
