U.S. Route 97 (US 97) is a United States Numbered Highway, stretching from Weed, California to the Canadian border in Oroville, Washington.

[8] US 97 was created in 1926 and originally terminated near Ashland, Oregon, but was extended from Klamath Falls to Weed in 1935.

[9] In 2002, Caltrans allocated $23.7 million to construct a 2.6-mile (4.2 km) bypass of Dorris to carry US 97 traffic, replacing a set of city streets with three turns that caused tractor trailers to flip over.

[10] The proposal was rejected by the city government in 2003 due to fears it would affect business traffic, which had already been struggling in Dorris.

[11] Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage.
