Oregon Route 120 (OR 120) is a 2.71-mile-long (4.36 km) unsigned state highway in the U.S. state of Oregon. The highway is internally known by the Oregon Department of Transportation (ODOT) as Swift Highway No. 120. OR 120 runs from a Union Pacific railroad crossing near North Columbia Boulevard to an interchange with Interstate 5 (I-5) and OR 99E. The Swift Highway No. 120 was created 1931 while the OR 120 designation was created in 2002.

Route description[edit]

OR 120 begins at a Union Pacific railroad crossing north of an interchange with North Columbia Boulevard.[1][2][3] The highway continues northeast as North Portland Road and follows BNSF Railway tracks.[3][4] About half of a mile (0.8 km) from where the highway begins, the OR 120 crosses the Columbia Slough using a bridge. OR 120 continues to follow BNSF Railway tracks and passes through wetlands before having a T-intersection with North Marine Drive.[3][4] The highway continues southeast as North Marine Drive, following the Columbia River shoreline. The highway ends at an intersection with OR 99E and the ramps to I-5. The Portland Expo Center is located near this interchange.[3] OR 120 is unsigned for its entire length.[1]

OR 120 is internally known by ODOT as Swift Highway No. 120.[5] The entire length of OR 120 is part of the National Highway System,[6] a network of roads important to the country's economy, defense, and mobility.[7]


The Swift Highway No. 120 was established as a secondary highway by the Oregon State Highway Commission on December 3, 1931. On November 22, 1966, a section of the Swift Highway between North Columbia Boulevard and an Oregon–Washington Railroad and Navigation Company railroad crossing was truncated.[8] The OR 120 designation was applied to the Swift Highway on July 24, 2002.[1] On July 22, 2008, maintenance for portions of the highway were transferred from ODOT to the city of Portland. The sections that were transferred are from the highway's western terminus to the southeastern end of the Columbia Slough bridge, and the northeastern end of the Columbia Slough Bridge to the end of concrete pavement just east of North Chatham Avenue.[8][3]

Major intersections[edit]

The entire route is in Portland, Multnomah County.
