History

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".''Oakland Tribune'' article, Tues. June 19, 1934 page 5. "NEW AIRLINE, HIGHWAY TO L.A. PLANNED."
