Nile Valley Landslide, 2009

The new route for Washington State Route 410 will go around the toe of the Nile Valley landslide. The 2009 Nile Valley landslide blocked the highway and diverted the Naches River. The DOT selected the route out of 3 possible options. The other two options were to remove the slide and keep the same alignment, or to make permanent the temporary detour that goes through a normally quiet rural neighborhood. [Source: KIMA CBS 29.
