Oregon Route 8, also known as Oregon Highway 8, is an Oregon state highway which serves the western suburbs of Portland. The road is locally known as Canyon Road and Tualatin Valley Highway, and travels through the center of the Tualatin Valley. Oregon 8 is located entirely within Washington County. The portion of the route from US 26 to Oregon Route 47 is part of the National Highway System, listed as a principal arterial.
The eastern terminus of OR 8 is an interchange with U.S. Route 26 (which is, at that point, the Sunset Highway) just west of the Portland city limits and the Washington-Multnomah county line. Initially, it is also known as Canyon Road, since it comes out of the gulch in which the Sunset Highway runs. The official designation, beginning from the eastern terminus, is the Tualatin Valley Highway No. 29 (see Oregon highways and routes).
Continuing west, OR 8 enters the suburb of Beaverton, and after its interchange with Oregon Route 217, a freeway, its posted name changes to the Tualatin Valley (TV) Highway at Hocken Avenue. It comes within one block of Oregon Route 10, running parallel but never intersecting, although commuters often use surface streets to change between the highways.
