(Prosser, WA) -- A 500-600 acre brush fire burned along I-82 about 5 miles east of Prosser Saturday afternoon. The fire, the origins of which are unclear, began to burn in standing wheat in a large field above the freeway. The flames were close the actual shoulder of the road, but Benton County Fire District Two's Mike McKenna told Newsradio they did not believe it would be necessary to close the road at this time. There were no evacuations and no damage to property. Part of the fire was burning on BLM-managed land and authorities were preparing to call in a fixed wing aircraft to help battle the blaze. Authorities say they expect to be on scene until at least midnight trying to contain the fire.
