Oregon Route 8

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 Tualatin Valley Highway, which is highway number 29, often abbreviated as TV Highway.[1]

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 TV Highway. 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.

TV Highway continues west as an expressway, out of Beaverton, through unincorporated urban Washington County (running right next to some of the chipmaker Intel's facilities) and into the suburb of Hillsboro.

After passing through downtown Hillsboro, OR 8 moves westward through the adjoined towns of Cornelius and Forest Grove, passing next to Pacific University. In Forest Grove, it intersects with Oregon Route 47, where it becomes part of the Nehalem Highway No. 102. West of Forest Grove, OR 8 is known as Gales Creek Road, which is not actually a state highway; after passing though some farmland west of Forest Grove, OR 8 reaches its western terminus in an intersection with Oregon Route 6 near the community of Glenwood.
