The Columbia River Highway is the nation's oldest scenic highway. In 1984 it was recognized as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers. In 2000 it was designated a National Historic Landmark by the National Park Service as "an outstanding example of modern highway development". Modern highways, including I-84, and other developments have resulted in the abandonment of major sections of the historic original highway, but forty miles of the highway remain open to motor vehicles including the 24 westernmost miles that provides access to Multnomah Falls, seen here. circa 1960.
