SR 267 is not part of the National Highway System,[2] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[3] The route from I-80 to Brockway Road is named the CHP Officer Glenn Carlson Memorial Bypass after CHP officer Glenn W. Carlson, who was killed along the route in 1963.[4]
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 (for a full list of prefixes, see California postmile § Official postmile definitions).[5] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
