What is the Historic Columbia River Highway?
The Historic Columbia River Highway was constructed between 1913 and 1922. In the early 1950s, many miles were damaged or destroyed to pave the way for I-84. Currently, an effort is underway to restore all 73 miles of the highway from Troutdale to The Dalles. Some segments, known as the Historic Highway State Trail, will be accessible only by people walking, rolling or biking. We are so close to completing the restoration of all 73 miles. Two projects are underway, with the last 1.6 mile segment scheduled to begin construction when funding is secured.
We are so close to completing the restoration of all 73 miles. Two projects are underway now!
