U.S. Route 20 (US 20) is a major west-east cross-state highway in the northern part of the U.S. state of Oregon, especially east of the Cascade Mountains. It connects U.S. Route 101 in Newport on the central Oregon Coast to the Idaho state line east of Nyssa.

Route description
US 20 starts at an intersection with US 101 in Newport, and travels eastward over the Central Oregon Coast Range to Corvallis. In Corvallis, it intersects Oregon Route 99W (OR 99W) and briefly travels concurrent with OR 34 before proceeding northeast to Albany. From Albany, US 20 briefly travels concurrent with OR 99E before turning east through Lebanon and Sweet Home and entering the Cascade Mountains. It intersects OR 126 west of Santiam Pass and the two routes travel concurrent through Sisters. US 20 then continues eastward and southward to Bend, where it travels roughly parallel to US 97 for about 3 miles (4.8 km) before turning east through Brothers and Riley. At Riley, US 20 travels concurrent with US 395 through Hines and Burns to about 2 miles (3.2 km) northeast of Burns. From Burns, US 20 continues east through Juntura and Vale. In Vale, US 20 travels concurrent with US 26, and the two highways continue east to Cairo Junction, south of Ontario, and turn south, where they then also travel concurrently with OR 201 to Nyssa. Eastward from Nyssa, US 20/US 26 continue to the Idaho state line.

Future
Construction on a portion of US 20 between Newport and Corvallis, specifically, from just west of Chitwood to Eddyville, is being done to straighten and remove nearly 4.5 miles (7.2 km) from the route. Nearly all of the new highway was opened in October 2016, with just a small portion of new road at the west end, and further environmental remediation, to be completed in 2017. The project made it easier for larger vehicles to travel, provided greater passing opportunities, and upgraded the highway to modern safety standards. Construction began in 2005, but was halted in 2007 because of excessive unexpected landslides. The project recommenced in May 2008 with a better plan for stabilizing these landslide locations. The final construction was expected to be completed in 2011, but continuing earth movement at four of the bridge sites delayed the project again. The Oregon Department of Transportation (ODOT) and the contractor were in a dispute over liability and money, a settlement was agreed upon, and the original design-build contract was rescinded. ODOT assumed control of the project and began completing the project in five phases, replacing the troublesome bridges with earth fill. Because of the previous delays, completion of the project was postponed until fall of 2016 for traffic on the road section, and late summer of 2017 for habitat improvement. The project is now estimated to cost $365.7 million.
Oregon highway designations
The Oregon section of US 20 consists of the following highways numbered using ODOT's internal numbering system (see Oregon highways and routes), from west to east:
- The Corvallis-Newport Highway No. 33;
- Part of the Corvallis-Lebanon Highway No. 210;
- The Albany-Corvallis Highway No. 31;
- The Santiam Highway No. 16;
- Part of the McKenzie Highway No. 15;
- The McKenzie-Bend Highway No. 17;
- The Central Oregon Highway No. 7.
Major intersections
Milepoints are as reported by ODOT and do not necessarily reflect current mileage. Z indicates overlapping mileage due to construction longer than established route, and - indicates negative mileage behind established beginning point. Segments that are locally maintained may be omitted. For routes traversing multiple named state highways, each milepoint is preceded by the corresponding state highway number.
