The "Historic Highway" refers to a network of roads that have significant cultural, historical, or architectural importance. These highways often showcase landmarks, scenic views, and sites that reflect the history of a region. They serve as a way to preserve and promote the heritage of the areas they traverse. One notable example is the Historic Columbia River Highway in Oregon, which was the first scenic highway in the United States. Completed in the early 20th century, it features stunning views of the Columbia River Gorge and includes various bridges and viewpoints that highlight the natural beauty and history of the region.
