A landslide has blocked the westbound lane of U.S. Highway 64 in Polk County, Tenn.
Jennifer Flynn, spokeswoman for the Tennessee Department of Transportation, said crews are breaking up rocks to clear the slide, which is between Maddens Branch and state Highway 30. Flaggers are directing traffic in the open eastbound lane.
She said geotechnical engineers are coming in from Nashville to assess the area to determine when the roadway is safe to reopen to two lanes.
