Published in 2007 by Clarence E. Mershon, The Columbia River Highway from the Sea to the Wheatfields of Eastern Oregon chronicles the grand engineering vision and historical evolution of one of America's most scenic roadways. The book details the monumental construction efforts led by Samuel C. Lancaster to carve a paved highway through the formidable cliffs of the Columbia River Gorge, connecting Portland's maritime climate to the vast agricultural interior. Through detailed historical narratives and vintage photographs, the text illustrates how the highway fundamentally transformed regional travel, commerce, and tourism by replacing precarious riverboats with a unified overland route. A keen insight drawn from the work is how the highway's pioneering design philosophy deliberately prioritized aesthetic wonder over pure utilitarian efficiency, transforming a piece of heavy civic infrastructure into a monumental landscape architecture project meant to romanticize the Pacific Northwest frontier for early motorists.
