Route description

OR 18 begins (at its western terminus) at a junction with U.S. Route 101, a few miles north of Lincoln City. In the US state of Oregon, US Route 101 a major north-south U Lincoln City is a city in Lincoln County, Oregon, United States. From there it winds eastward though the coast range along the Salmon River), and through a stand of timber known as the Van Duzer Corridor. The Salmon River is a short coastal river approximately 20 mi (32 km long on the Pacific coast of northwest Oregon in the United States. Emerging from the coast range, it enters the fringes of the Willamette Valley in the community of Grand Ronde. Grand Ronde is a Census-designated place (CDP in Polk County, Oregon, United States. It is briefly joined by Oregon Route 22 at a location known as Valley Junction, and overlaps OR 22 in a several-mile stretch between Grand Ronde and Willamina, at which point OR 22 heads southeast towards Salem and OR 18 continues northeast towards the Portland area. Oregon Route 22 is an Oregon State highway that runs between the Oregon Coast community of Hebo, to an interchange with U Willamina is a city in Polk and Yamhill Counties in the US state of Oregon. Salem (ˈseɪləm is the Capital of the US state of Oregon, and the County seat of Marion County. Portland is a city located in the Northwestern United States, near the Confluence of the Willamette and Columbia rivers Also in Willamina, a business route veers off to the north to serve the towns of Willamina and Sheridan; east of Sheridan the business route rejoins the mainline. Sheridan is a city in Yamhill County, Oregon, United States. The population was 3570 at the 2000 census This business loop was the former route and highway until 1957, when the current Oregon Route 18 was built as a bypass.

The highway continues northeast on a straight and level course through Willamette Valley farmland, until it intersects with Oregon Route 99W just south of McMinnville. Oregon Route 99W is a State-numbered route in Oregon, United States that runs from OR 99 and OR 99E in Junction City McMinnville is the County seat and largest city of Yamhill County, Oregon, United States. In the McMinnville area, OR 99W serves as the primary business route (entering the downtown core) whereas OR 18 is a bypass route. Two interchanges along OR 18 provide access to McMinnville, including Three-Mile Lane, a spur of the highway. Oregon Route 18 provides direct access to the McMinnville Airport and the Evergreen Aviation Museum, home of the Spruce Goose. McMinnville Municipal Airport, is a public Airport located three miles (4 The Evergreen Aviation & Space Museum is an aviation Museum which displays a number of Military and Civilian Aircraft and Spacecraft WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout East of McMinnville, Oregon Route 18 intersects Oregon Route 233, with which it overlaps until its eastern terminus, and Oregon Route 221; the latter near the town of Dayton. Oregon Route 233 is an Oregon State highway which runs between the cities of Amity and Dayton, USA in the Willamette Valley. Oregon Route 221 is an Oregon State highway which runs between the city of Salem Oregon and the city of Dayton Oregon, roughly along the western Dayton is a city in Yamhill County, Oregon, United States. The population was 2119 at the 2000 census It then crosses over the Yamhill River and terminates at a second junction with OR 99W. The Yamhill River is a tributary of the Willamette River, approximately 12 miles (19 km long in northwestern Oregon in the United States. Typically, commuters continue north on OR 99W into the Portland area.

The highway is rather variant in its configuration. For most of its length, the highway is a two-lane undivided highway, with intersections and cross traffic. There are some limited-access stretches in the "bypass" sections (around the Willamina/Sheridan area, and near McMinnville and Dayton), and the occasional interchange in these stretches. In addition, there is a stretch between Willamina and Sheridan where the highway becomes a 4-lane divided expressway. An expressway is a Divided highway for high-speed traffic with at least partial Control of access.

Currently, the route has a rather notorious reputation among motorists in Oregon, with a relatively high number of fatal accidents. The opening of two casinos, one in Grand Ronde and one in Lincoln City, have greatly increased traffic on OR 18. A casino is in the modern sense of the word a facility that houses and accommodates certain types of Gambling activities (In addition, the stretch of Oregon Route 99W immediately north of Dayton, through Dundee and Newberg, is a notorious traffic bottleneck. Dundee (ˈdʌndiː is a city in Yamhill County, Oregon, United States. Newberg is a city in Yamhill County, Oregon, United States. A tradition holds that this town was named by its first postmaster Sebastian Brutscher for ) Portions of Oregon Route 18 have been designated a safety corridor.

There are two proposed expansions to the highway. One is a project which would widen Oregon Route 18 to a four-lane expressway in the stretch between Grand Ronde and Willamina; an area where increased volume (largely due to the casino) has caused significant delays.

The second project is a new bypass around the Newberg-Dundee area intended to alleviate severe congestion that occurs along 99W. A bypass is a Road or Highway that avoids or "bypasses" a built-up area town or village to let through Traffic flow without interference from Newberg is a city in Yamhill County, Oregon, United States. A tradition holds that this town was named by its first postmaster Sebastian Brutscher for Dundee (ˈdʌndiː is a city in Yamhill County, Oregon, United States. This new route will either be an expressway or a freeway. A route number for this latter project has not been published; however planning documents and maps present it as an extension to Oregon Route 18.
