It connects U.S. Route 101 in Newport on the central Oregon Coast to the Idaho state line east of Nyssa. U.S. Route 20 in Oregon begins at an intersection with U.S. 101 in Newport, and runs eastward over the Central Oregon Coast Range to Corvallis. In Corvallis, it intersects Oregon Route 99W and briefly overlaps Oregon Route 34 before proceeding northeast to Albany. From Albany, U.S. 20 briefly overlaps Oregon Route 99E before turning east through Lebanon and Sweet Home and entering the Cascade Mountains. It intersects Oregon Route 126 west of Santiam Pass and the two routes overlap through Sisters. U.S. 20 then continues eastward and southward to Bend, where it overlaps U.S. 97 for about 5 miles before turning east through Brothers and Riley.
