A tire or brake failure is the likely source of a semi fire that slowed traffic Monday morning on U.S. 6 in Spring Spring Valley.
Spring Valley Fire Chief Todd Bogatitus said a semi carrying soybeans caught fire, though the quickly-extinguished fire was limited to a rear axel and might have been the result of a blowout. Bogatitus said firefighters were on scene about half an hour in the 200 block of West Dakota Street and cleared the scene around 10 a.m.
