Grass fire and downed lines on West Andrew Johnson

As discussed during the dispatch call, emergency crews respond to a reported grass fire in the highway median near the Mosheim post office. Radio traffic indicates a tractor trailer may have struck overhead utility lines, possibly telephone or cable, causing them to hang across the roadway and reportedly sparking the fire. Traffic is being detoured through the post office parking lot, and four lanes of the highway appear to be temporarily closed while responders investigate and manage the scene.
