Oregon Route 66 is anOregonstate highway that runs between the cities ofAshland andKlamath Falls. The highway is known as theGreen Springs Highway No. 21 (seeOregon highways and routes), and is signed east-to-west.
Oregon Route 66 begins (at its western terminus) at an intersection withOregon Route 99 just east of downtown Ashland. The highway heads northeast, crosses and intersects withInterstate 5, and continues east along the northern edge of theSiskiyou Mountains. Before ascending into the mountains, it passes alongsideEmigrant Reservoir. Six miles east of Ashland, the highway intersects withOregon Route 273, near theKlamath Falls Junction.
The highway then passes over the mountains. The highway ends at an interchange withU.S. Route 97 in Klamath Falls; just west of this interchange the highway intersects and briefly overlapsOregon Route 140. OR 140 continues east of the US 97 interchange, past the Klamath Falls airport, and eventually towardsLakeview.
Prior to 1934, the stretch of OR 66 between Klamath Falls Junction and Klamath Falls was signed as US 97; when the highway between Klamath Falls andWeed, California was completed, that route became US 97, and the Green Springs Highway became OR 66. At that time, OR 66 west of Klamath Falls Junction (and OR 273 south of there) wasU.S. Route 99; in 1938 a new route overSiskiyou Pass was completed, and the highway assumed its current configuration.
OR 66 is 59 miles (95 km) in length.
