Historic Columbia River Highway, Troutdale, Multnomah County, OR
Summary
Significance: The Historic Columbia River Highway is one of the oldest scenic highways in the United States. It was an early twentieth-century technical and civic achievement, successfully mixing sensitivity to a magnificent natural landscape with ambitious engineering. The route has gained national significance because it represents one of the earliest applications of cliff-face road building as applied to modern highway construction. Much of the original highway remains as a scenic route for less hurried travelers who look forward to experiencing the many natural wonders of the Columbia River Gorge.
