When defined in 1963, the route began at I-280 and ended at US 101. In 1984, a segment of SR 84 in the vicinity was swapped with SR 114, moving SR 114 from I-280 to SR 84, which followed Willow Road, as it does today. In 1990, however, the I-280 section was truncated and the terminus was switched to US 101.[2]
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).[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in San Mateo County.
