State Route 161 (SR 161) is a state highway in the U.S. state of California that runs along the California–Oregon state line in Siskiyou County. It begins at U.S. Route 97 north of Dorris and goes east to the intersection of SR 139 and Oregon Route 39 north of Tulelake. SR 161 is part of the Volcanic Legacy Scenic Byway.

Route description[edit]

SR 161 begins at an intersection with U.S. Route 97 north of Dorris. The route travels east past Indian Tom Lake, bending to the south and passing by Lake Miller and Sheepy Lake. SR 161 continues past the Lower Klamath National Wildlife Refuge, which includes Lower Klamath Lake, and White Lake, now paralleling the state line again to the intersection of Route 139 and Oregon Route 39 north of Tulelake in the community of Hatfield.[2]

SR 161 is not part of the National Highway System,[3] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[4] SR 161 is eligible for the State Scenic Highway System,[5] but it is not officially designated as a scenic highway by the California Department of Transportation.[6]

SR 161 is part of a spur route of the Volcanic Legacy Scenic Byway, an All-American Road, that heads towards Tule Lake and Lava Beds National Monument.[7]

Major intersections[edit]

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 California postmile § Official postmile definitions).[8] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Siskiyou County.
