The southern terminus of SR 269 is at State Route 33 in Avenal, where it drops into the San Joaquin Valley at I-5. In the city of Avenal, it is known as Skyline Boulevard. From the Fresno-Kings county line, right before I-5 to its northern terminus at SR 145, the road is known as Lassen Avenue and heads due north through Huron.
Except where prefixed with a letter, postmiles were measured on the road as it was when the route was established, 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.
