Don't miss the Historic Columbia River Highway. It is an approximately 75-mile-long (121 km) scenic highway in the U.S. state of Oregon between Troutdale and The Dalles, built through the Columbia River Gorge between 1913 and 1922. As the first planned scenic roadway in the United States, it has been recognized in numerous ways, including a listing on the National Register of Historic Places as a National Historic Landmark, designation as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers, and considered a "destination unto itself" as an All-American Road by the U.S. Secretary of Transportation.
Stunning beautiful scenes overlooking the Columbia River through old growth rain forest traveling on a two lane highway intended to show off the beauty and blend into the surroundings. The highway and bridges are a sight unto themselves.
