Upon reaching Hollister, the route turns into a four-lane undivided road, curving north and west through the east side of the city. North of Hollister, SR 25 reverts into a 2-lane road and continues northwest from Hollister, intersecting with State Route 156. From there, the route is a partially divided road until just short of a railroad crossing and eventually crossing the Pajaro River into Santa Clara County. The route then heads northwest, and at the intersection with Bloomfield Avenue, the route then curves west before its northern terminus at U.S. Route 101 south of Gilroy.[3]

The Airline Highway Association was organized in 1933-4 and was composed of representatives of Alameda, Santa Clara, San Benito, Kern and Kings Counties. Its purpose was to establish this "Airline Highway". In the Oakland Tribune article, (Tues. June 19, 1934 page 5. "NEW AIRLINE, HIGHWAY TO L.A. PLANNED") it states "the highway would follow the air line between the northern and southern part of the state as closely as possible". The use of the word Airline is confusing as we associate it with modern-day transportation. In this sense it is defined as an Americanism dating back to 1805 meaning "traveling a direct route".[9]
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 numbers reset at county lines; the start and end postmiles in each county are given in the county column.
