U.S. Route 97 (US 97) is a United States Numbered Highway, stretching from Weed, California to the Canadian border in Oroville, Washington. The California portion of US 97 runs north from I-5 in Weed to the Oregon state line. This is the majority of a shortcut between I-5 and Klamath Falls, Oregon, added to both states' state highway systems in 1931.
US 97 begins in Weed at an interchange with Interstate 5. It runs on Weed's Business Loop of Interstate 5, which all of the loop used to be U.S. Route 99. At the junction with California State Route 265, U.S. Route 97 ends its concurrency with the Business Loop and turns right, heading to the northeast into the Shasta-Trinity National Forest, and later the Klamath National Forest. US 97 passes by Grass Lake as it travels through the mountains before descending into the community of Macdoel. The route continues into the city of Dorris before intersecting with California State Route 161 near Indian Tom Lake before it crosses Oregon state border and leaves California.
US 97 is part of the California Freeway and Expressway System, and is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration. US 97 is eligible for the State Scenic Highway System, but it is not officially designated as a scenic highway by the California Department of Transportation. US 97 is also part of the Volcanic Legacy Scenic Byway, an All-American Road.
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. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see the list of postmile definitions). Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Siskiyou County.
