Oregon Route 99W is astate-numbered route inOregon,United States, that runs fromOR 99 andOR 99E inJunction City north toI-5 in southwesternPortland. Some signage continues it north toUS 26 near downtown, but most signage agrees with theOregon Department of Transportation's (ODOT) description, ending it at I-5.[1][2] OR 99W is known by ODOT as thePacific Highway West No. 1W (seeOregon highways and routes); that highway continues north through downtown (along a former extension of OR 99W) to thePacific Highway No. 1 (I-5) in northern Portland, as well as south on OR 99 to the Pacific Highway (I-5) inEugene.
Until around 1972, OR 99W wasU.S. Route 99W, rejoining OR 99E (formerlyUS 99E) in northern Portland.US 99 then continued north along present I-5 intoWashington; the next segment still numbered 99 isWA 99 south ofSeattle.
The Pacific Highway West begins at theinterchange with I-5 (Pacific Highway) andOR 126 Business (McKenzie Highway No. 15) in easternEugene. It heads west through downtown Eugene alongOR 99 and OR 126 Business, and then northwest and north toJunction City on OR 99.
At Junction City, OR 99 ends and OR 99W begins along the Pacific Highway West, while OR 99E heads northeast on theAlbany-Junction City Highway No. 58. While OR 99E quickly crosses theWillamette River, OR 99W stays on its west side through theWillamette Valley, passing through towns such asMonroe,Corvallis,Monmouth,Rickreall,Amity,McMinnville andLafayette.Oregon Route 18 provides a bypass for OR 99W around downtown McMinnville and Lafayette.
At McMinnville, OR 99W turns northeast. It passes through thewinemaking towns ofDundee andNewberg before entering the Portlandsuburb ofSherwood.OR 18 provides a partial bypass for OR 99W around downtown Dundee and Newberg. The bypass currently ends at OR 219, but is proposed to extend northeast to OR 99W northeast of Newberg. OR 99W then skirts the city ofTualatin and passes throughTigard where it becomes Barbur Boulevard before enteringPortland and immediately ending at I-5.
The Pacific Highway West, however, continues northeast and north, paralleling I-5 on Barbur Boulevard.OR 10 joins at Capitol Highway, which is not a state highway. South of theRoss Island Bridge approach, Oregon Highway 99W and OR 10 split from Barbur Boulevard ontoNaito Parkway, an arterial that once connected directly toHarbor Drive. OR 10 ends at the west end of the Ross Island Bridge, which carriesUS 26, theMt. Hood Highway No. 26. Until around 2005, US 26 came off the bridge onto the Pacific Highway West north into downtown Portland, but it now heads west on the locally maintained Arthur Street to reachI-405.
At the overpass over I-405 is the former split with Harbor Drive, which was replaced byTom McCall Waterfront Park in 1974. The road now runs into Naito Parkway (formerly Front Avenue), and is state-maintained until Market Street, the eastbound half of theone-way pair of theSunset Highway (US 26 left the Pacific Highway West here prior to ca. 2005).

The Pacific Highway West continues north through downtown, locally maintained along Naito Parkway, to the state-maintainedSteel Bridge. There is a direct ramp for northbound traffic onto the bridge, but the former southbound ramp is now used by theMAX Light Rail system, and so southbound traffic must head west to 3rd Avenue, three blocks west of Naito Parkway.
At the northeast end of the Steel Bridge, the Pacific Highway West again becomes locally maintained, and heads north onInterstate Avenue all the way to I-5 (thePacific Highway) near theInterstate Bridge. It is again state-maintained north of Argyle Street.

The first highway in the corridor was the Capitol Highway (Highway 3), from Portland to Salem via Dayton (roughly present OR 99W andOR 221). In 1927 it was merged with theWest Side Highway, which ran from Dayton to Junction City, to form the West Side Pacific Highway, still numbered 3, and a western loop of the Pacific Highway (Highway 1/U.S. Route 99). (The former Capitol Highway south of Dayton was removed from the system, but was later taken over as theSalem-Dayton Highway.) The section north of Portland was initially named Multnomah Boulevard until Interstate Avenue was adopted in 1916; the street was paved in the late 1920s amid several minor realignments to provide for a 100-foot (30 m) wide highway.[4]
In 1930, Highway 3 was assigned the U.S. Route 99W number and Highway 1 (old US 99) between the ends of Highway 3 became US 99E.[5] Highway 1 was similarly split in 1938, forming the Pacific Highway West - Highway 1W - and thePacific Highway East, Highway 1E. Highway 1W was formed from Highway 3, and extended north on Interstate Avenue to just south of theInterstate Bridge.
In 1957, with the assignment of I-5, the Pacific Highway (Highway 1) was moved to its planned alignment, resulting in an extension of Highway 1W south toEugene. US 99W however continued to terminate at Junction City; the new I-5 was designated US 99 when it opened in 1961. (US 99W from south of downtown Portland north to its end was temporarily part of US 99 from 1961 to 1963, when I-5 opened north of downtown.)
US 99 became OR 99 in December 1971, resulting in the renumbering of US 99W to OR 99W. It was truncated in 1979 to I-5 just north of the Tigard/Portland line. It was again re-extended to south of downtown in 1996, with various signs identifying it as 99W placed sporadically between downtown and Tigard.
The original alignment in southern Portland, bypassed in the 1930s by Barbur Boulevard, is still called Capitol Highway. It begins at the present north end of OR 99W and runs first east, then west, of Highway 1W, eventually merging withOR 10 (formerly theBeaverton-Hillsdale Highway) before ending at Highway 1W south of downtown.
Through downtown Portland, the original alignment took US 99W across theBroadway Bridge, reaching it via 4th Avenue, Burnside Street, and Broadway northbound, and Broadway, Pine Street, and 6th Avenue southbound.[6] In 1950 it was realigned alongHarbor Drive, theSteel Bridge and a realigned Interstate Avenue. Harbor Drive was removed in 1974, resulting in OR 99W moving west one block to Front Street (now Naito Parkway) downtown.
