Crown Point Viaduct

The Crown Point Viaduct in Corbett, Oregon is a 600’ long concrete structure located on the Historic Columbia River Highway, adjacent to the Vista House. The purpose of this structure is to carry the highway around the rock formation at Crown Point – which was a serious obstacle to its construction in 1914. It includes a 7’ wide sidewalk, a micro-pile foundation wall along the inside of the viaduct and 29 support columns. The Historic Columbia River Highway is one of only two roads in the United States designated as a National Historic Landmark, a National Scenic Byway, and a National Historic District.
