The Columbia River Highway, now known as the Historic Columbia River Highway, was a technical and civic achievement of its time, successfully mixing ambitious engineering with a sensitivity to the magnificent landscape of the Columbia River Gorge. Entrepreneur and Good Roads promoter Samuel Hill teamed up with engineer and landscape architect Samuel C. Lancaster to create a highway that would make the idyllic natural setting accessible to tourists without unduly marring its beauty. When the first section of road opened in 1915, the Columbia River Highway became the first paved highway in the Pacific Northwest.....
......Constructed from 1913 to 1922, the seventy-four-mile Columbia River Highway extended east from the Sandy River near Troutdale to The Dalles. With its pioneering advances in road design, the road is an outstanding example of modern highway development in twentieth-century America. Patterned after the roads of western Europe and the British Isles, the design included the adherence to grade and curve standards, comprehensive curb and drainage systems, dry and mortared masonry walls, reinforced-concrete bridges and tunnels, and asphaltic concrete pavement
Columbia River Highway Historic District is on the National Register of Historic Places from 1983.
From 1984, it is a National Historic Civil Engineering Landmark by the American Society of Civil Engineers.
