Oregon Route 99W - Route Description

Route Description

The Pacific Highway West begins at the interchange with I-5 (Pacific Highway) and OR 126 Business (McKenzie Highway No. 15) in eastern Eugene. It heads west through downtown Eugene along OR 99 and OR 126 Business, and then northwest and north to Junction 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 the Albany-Junction City Highway No. 58. While OR 99E quickly crosses the Willamette River, OR 99W stays on its west side through the Willamette Valley, passing through towns such as Monroe, Corvallis, Monmouth, Rickreall, Amity, McMinnville and Lafayette. Oregon Route 18 provides a bypass for OR 99W around downtown McMinnville and Lafayette.

At McMinnville, OR 99W turns northeast. It passes through the winemaking towns of Dundee and Newberg before entering the Portland suburb of Sherwood. (There is a proposal to bypass these towns; see the OR 18 article for details.) It then skirts the city of Tualatin and passes through Tigard before entering Portland 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 the Ross Island Bridge approach, Oregon Highway 1W and OR 10 split from Barbur Boulevard onto Naito Parkway, an arterial that once connected directly to Harbor Drive. OR 10 ends at the west end of the Ross Island Bridge, which carries US 26, the Mt. 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 reach I-405.

At the overpass over I-405 is the former split with Harbor Drive, which was replaced by Tom 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 the one-way pair of the Sunset 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-maintained Steel Bridge. There is a direct ramp for northbound traffic onto the bridge, but the former southbound ramp is now used by the MAX 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 on Interstate Avenue all the way to I-5 (the Pacific Highway) near the Interstate Bridge. This is again state-maintained north of Argyle Street.
