This road, owned by the Museum of Art, is open publicly for non-motorized traffic. While it is best known among downhill skateboarders for its steepness, smooth pavement, and lack of traffic, it is also popular for cycling and roller skating. Walking along the road, with its steep grade and many curves, offers a workout and excellent views of the Columbia River Gorge. Watch out for people coming down the hill, however, as skateboarders have reported speeds in excess of 50mph.
The Maryhill Loops Road was an experimental road in south central Washington, United States, built by Good Roads promoter Samuel Hill with the help of engineer and landscape architect Samuel C. Lancaster. Laid in 1911 as the first asphalt road in the state, it achieved low grades with horseshoe curves. It was bypassed by the present, straighter U.S. Route 97 after World War II.
