Route description
SR 172 begins at a junction with SR 36 in Mineral and heads southeast through Lassen National Forest. The route then turns south, crossing the South Fork Battle Creek and entering a wooded area. The road then winds eastward through the forest, roughly parallel to Mill Creek. SR 172 then turns northward along Mill Creek and heads back toward SR 36 in Morgan Springs, its eastern terminus.[2]
The segment between Mineral and Mill Creek is not plowed during the winter and thus is typically closed during snowy conditions.[3][4]
SR 172 is not part of the National Highway System,[5] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[6]
Major intersections
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 to an overlap due to a correction or change, and T indicates postmiles classified as temporary ().[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Tehama County.
