Projected circuit based on accounts.
A 11.15 mile road circuit used between 1911 and 1915. The circuit was proposed by a group of Kern River oil men in order to promote the city, with the circuit to be built through the oilfield on the outskirts of the city. The proposed circuit only existed in the minds of the proposers, so a great deal of effort was expended to secure rights of way, to arrange with the Southern Pacific Rail Company to halt traffic on the spur line crossing the race course, to build bridges and to straighten and realign sections of road. They also had to secure sanction from the AAA to hold the race. The various oil companies put more than 200 men to work on the course, and it was completed in time for the first race on the 4th July, 1911.
