In this May 20, 2014 photo, heavy machinery is used to place dirt and rock along what will eventually be an improved mountain highway, during a road-building operation on Highway 36 between Lyons at Estes Park, Colorado. The goal of the project is to move the road further from the adjacent river, which undermined the road for miles during floods the previous fall, in hopes of preventing such destructive flooding in the future.
