==Route description== OR 10 begins as Naito Parkway in Downtown Portland starting where Naito Parkway interchanges with U.S. Route 26. It heads south out of downtown, multiplexed with Oregon Route 99W. After passing under the Portland Aerial Tram, Naito Parkway ends at an interchange with Barbur Boulevard; the two routes continue south out of Portland on Barbur. OR 10 separates from OR 99W a few miles south of downtown, and proceeds along Capitol Highway through the Portland neighborhood of Hillsdale. Along here, it is a surface street, which cuts through the southern part of Portland's West Hills. It separates from Capitol Highway in Hillsdale, which continues unnumbered. The highway continues west into Washington County, where it becomes '''Beaverton-Hillsdale Highway No. 40.'''<ref name="GIS">Oregon Department of Transportation, [https://gis.odot.state.or.us/transgis/|ODOT TransGIS], accessed January 2026</ref>
In the community of Raleigh Hills, OR 10 intersects with Oregon Route 210 (locally known as Scholls Ferry Road), which heads southwest towards Progress, Tigard, and Scholls. OR 10 continues west into Beaverton, where it interchanges with Oregon Route 217, a freeway, and stops being '''Beaverton-Hillsdale Highway No. 40.'''<ref name="GIS" /> West of that interchange, the street name changes to Farmington Road, the eastern part of which is not a state highway, and comes a block parallel with Oregon Route 8 in front of Beaverton High School. The portion of OR 10 from downtown Beaverton to the intersection with Oregon Route 219 was once known as Oregon Route 208. OR 8 and 10 no longer intersect, but it is not uncommon for commuters to use the frontage road for the OR 217 interchange or another surface street to change between the routes. As Farmington Road, OR 10 leaves Beaverton and cuts across half-developed suburbia to Farmington and its intersection with OR 219. This final section comprises '''Farmington Highway No. 142''', which extends for 1.5 miles east from SW 197th Avenue.<ref>State Library of Oregon, [https://digitalcollections.library.oregon.gov/nodes/view/206221|no. 142 Farmington Straightline charts], accessed January 2026</ref>

==History== The oldest section of Oregon Route 10 was Farmington Road. Established circa 1848 as part of a larger route from Lafayette, Oregon to Portland, Oregon, known as the Portland-Yamhill Falls Road. This section followed from the Harris Ferry in Farmington, Oregon, to Canyon Road in Beaverton, Oregon.<ref>{{cite web|url=https://mtbachelor.co.washington.or.us/images/survey/CoRoads/CR0A34.pdf|title=Portland-Yamhill Falls Road Via Harris' Ferry on the Tualatan|access-date=3 February 2026}}</ref> The specific route of the road would later become lost, and it would then be reestablished in its modern routing in 1898.<ref>{{cite web|url=https://mtbachelor.co.washington.or.us/images/survey/CoRoads/CR0359.pdf|title=County Road Number 359|access-date=3 February 2026}}</ref> In 1932, Farmington Road became part of Oregon's highway system, and was designated Oregon Route 208.<ref name="odothistory">{{cite web|url=https://www.oregon.gov/odot/ETA/Documents_Geometronics/ROW-Eng_State-Highway-History.pdf|title=History of State Highways in Oregon|access-date=9 February 2026}}</ref>
Initially, Farmington Road was referred under several names, such as the Harris Bridge Road, the Farmington and Portland Road, and the Portland-Lafayette Road, all interchangeably.<ref>{{cite web|url=https://mtbachelor.co.washington.or.us/images/survey/surveys/5000/701.pdf|title=701.pdf|access-date=9 February 2026}}</ref><ref>{{cite web|url=https://mtbachelor.co.washington.or.us/images/survey/surveys/5000/1708.pdf|title=1708.pdf|access-date=9 February 2026}}</ref><ref>{{cite web|url=https://mtbachelor.co.washington.or.us/images/survey/surveys/5000/2219.pdf|title=2219.pdf|access-date=9 February 2026}}</ref> The road would end up being referred to as the Campbell Bridge-Beaverton Road by the Oregon State Highway Department in 1928, and when it became a secondary highway in 1936, It was referred to as Farmington highway, with the constituent road being referred to as Farmington Road.<ref>{{cite web|url=https://mtbachelor.co.washington.or.us/images/survey/CoRoads/MR0004.pdf|title=Market Road Number 4|access-date=9 February 2026}}</ref><ref name="odothistory" />
Circa 1916-1918, the Beaverton-Hillsdale Highway would be established as the Bertha-Beaverton Road. The road ran from Broadway Road in Beaverton to Capitol Highway.<ref>{{cite web|url=https://mtbachelor.co.washington.or.us/images/survey/CoRoads/CR0669.pdf|title=C.R. 669 S.W Beaverton-Hillsdale Hwy.|access-date=9 February 2026}}</ref><ref>{{cite web|url=https://www4.multco.us/Surveyimages/Roads/RD0000-0999/RD0909-MAP.PDF|title=Map of the Bertha-Beaverton Road No. 909|last=Bonser|first=R.C.|access-date=9 February 2026}}</ref><ref>{{cite web|url=https://mtbachelor.co.washington.or.us/images/survey/surveys/10000/7709.pdf|title=RECORD OF SURVEY for TIME OIL COMPANY LOT 1 & 2, KURDY'S ADDITION to BEAVERTON SECTION 15, TlS, RlW, w.M.
