The highway serves the primary and most active coal producing region in Utah, accounting for about 2% of the coal supply of the United States[2] Several of the routes that spur from SR-10 to cross the Wasatch Plateau have been honored for their role in energy production. SR-31 has been named The Energy Loop as part of the National Scenic Byways program. Just off SR-10, along SR-29 is the location of the Wilberg Mine fire of 1984. According to a roadside memorial fire is the worst coal mine tragedy in Utah's history.[3] More recently the highway was mentioned in worldwide news as part of coverage of the Crandall Canyon Mine collapse of 2007.

Though the highway is not generally used for long haul traffic, the increase in coal extraction along the SR-10 corridor has caused the Utah Department of Transportation to push for funding for improvements calling it one of the most dangerous freight corridors in Utah[4] The northern portion of the highway is loosely paralleled by the Utah Railway that helps service the numerous coal mines along the highway corridor.
