'''Oregon Route 8''', also known as Oregon Highway 8, is an [[Oregon]] [[state highway]] which serves the western [[suburb]]s of [[Portland, Oregon|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, Oregon|Washington County]]. The portion of the route from [[U.S. Route 26 in Oregon|US 26]] to [[Oregon Route 47]] is part of the [[National Highway System (United States)|National Highway System]], listed as a principal arterial.<ref>[http://egov.oregon.gov/ODOT/TD/TDATA/gis/docs/countymaps/wash1.pdf Oregon Transportation Map: Washington County.] Oregon Department of Transportation.

==Route description==
The eastern terminus of OR 8 is an interchange with [[U.S. Route 26 in Oregon|U.S. Route 26]] (which is, at that point, the [[Sunset Highway (Oregon)|Sunset Highway]]) just west of the Portland city limits and the [[Washington County, Oregon|Washington]]-[[Multnomah County, Oregon|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]]).<ref>{{cite web |url=http://www.oregon.gov/ODOT/HWY/TRAFFIC/TEOS_Publications/PDF/Descriptions_of_US_and_Oregon_Routes.pdf |title=Archived copy |access-date=2007-10-30 |url-status=dead |archive-url=https://web.archive.org/web/20051102084300/http://www.oregon.gov/ODOT/HWY/TRAFFIC/TEOS_Publications/PDF/Descriptions_of_US_and_Oregon_Routes.pdf |archive-date=2005-11-02 }}</ref>

Continuing west, OR 8 enters the suburb of [[Beaverton, Oregon|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.

TV Highway continues west as an [[Limited-access road|expressway]] out of Beaverton, through the communities of unincorporated urban Washington County, including [[Aloha, Oregon|Aloha]], where it runs right next to chipmaker [[Intel|Intel's]] facilities. The highway continues into the Hillsboro neighborhoods of [[Reedville, Oregon|Reedville]] and [[Witch Hazel, Oregon|Witch Hazel]], where it intersects with [[Cornelius Pass Road]] at Reedville. It then continues into the city proper of [[Hillsboro, Oregon|Hillsboro]], running north&ndash;south as 10th Avenue before turning east&ndash;west with traffic split into a [[one-way pair]]. Westbound traffic runs as [[Willamette Stone|Baseline]] Street and eastbound traffic runs on Oak Street. In downtown Hillsboro it receives the northern terminus of [[Oregon Route 219]], which is 1st Avenue.

After passing through downtown Hillsboro, OR 8 moves westward through the adjoined towns of [[Cornelius, Oregon|Cornelius]] and [[Forest Grove, Oregon|Forest Grove]], passing next to [[Pacific University]]. At Cornelius the road is again split into a one-way pair, with westbound traffic running on Adair Street, and eastbound on Baseline. In Forest Grove, it intersects with [[Oregon Route 47]], where it becomes part of the [[Nehalem Highway]] No. 102. TV Highway continues as OR 47 south to McMinnville. In downtown Forest Grove the road splits again, with eastbound traffic running on 19th Street, and westbound on Pacific Avenue. West of Forest Grove, OR 8 is known as '''Gales Creek Road''', which is not actually a state highway; after passing through some farmland west of Forest Grove, including the community of [[Gales Creek, Oregon|Gales Creek]], OR 8 reaches its western terminus in an intersection with [[Oregon Route 6]] south of the community of [[Glenwood, Washington County, Oregon|Glenwood]].

==History==
The section between Beaverton and Hillsboro was built around 1918.<ref name="Reedville">{{cite news|title=Communities: Reedville named for early resident|last=Jensen|first=Doris|date=October 17, 1976|work=[[Hillsboro Argus]]|page=17}}</ref> Constructed of cement, it partly replaced a county road built of dirt that ran on the southern side of the railroad tracks.<ref name="Reedville"/> The earlier road came from Portland via Bertha Blvd. on [[Oregon Route 10|Farmington Road]] and veered north on what is now Kinnaman Road until 209th Avenue in Reedville, where it then ran parallel to the rail tracks.<ref name="Reedville"/> At [[Witch Hazel, Oregon|Witch Hazel]] it then followed the modern Witch Hazel and River roads into Hillsboro proper.<ref name="Reedville"/>

In March 1919, Hillsboro elected to have the highway moved from Main Street two blocks south to Baseline Street (eastbound traffic was later moved to Oak Street).<ref name="highways">{{cite news|title=Transportation: Highways, roads played vital role|last=Alexander|first=Paul|date=October 19, 1976|work=[[Hillsboro Argus]]|page=5}}</ref> Washington County planners in March 1953 decided to have the highway widened to four lanes.<ref name="highways"/>
