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

File:Santiam Pass.jpg

US 20 crossing the Cascade Range at Santiam Pass.

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 concurrent with US 97 for about 5 miles (8.0 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. The project will make it easier for larger vehicles to travel, provide greater passing opportunities and upgrade 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. ODOT and the contractor were in a dispute over liability and money, a settlement was agreed upon, and the original design-build contract has been rescinded. ODOT assumed control of the project, and began completing the project in five phases. Because of the previous delays the project has been 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.
