 | | Multnomah, Hood River, and Wasco Counties, OR When the 121kmlong (75mile) Columbia River Highway between Troutdale and The Danes was officially completed on June 27, 1922, it was hailed as one of the engineering marvels of its age. |
 | | The first paved highway in the Northwestern United States, the Columbia River Highway was conceived, designed, and constructed as both a scenic attraction and as a means of facilitating economic development along the Columbia River corridor between the Pacific Ocean and the areas to the east of the Cascade Mountains. |
 | | The history of the development, decline, and continuing rebirth of the Columbia River Highway is particularly instructive to the highway engineering community as we approach the beginning of a new century and a future of increasing reliance on the rehabilitation and restoration of existing infrastructure instead of the construction of new highways. |
