[2] The construction of the timber track on a 120-acre (49 ha) site began in mid-October 1914 under the direction of Jack Prince,[3] promoter and speedway builder, who employed the "triple radius corner" concept so that cars could enter the straightaways at full throttle.
[5] Work on the track resumed, though, and in mid-June 1915, C. R. Vaughn, the contractor who was assigned to complete the speedway, had almost finished the surface and the underground auto tunnel while the grandstands were still being built.
[6] The inaugural event was held on July 5, 1915 when 30,000 spectators watched former Omaha resident Eddie Rickenbacker win a 300-mile race with an average speed exceeding 91 miles per hour (146 km/h).
[7] Many fans were left disappointed, however, for only eight of 19 contracted drivers had started the race after several cars had been damaged at the previous meetings at Chicago and Sioux City.
[10] With the boards beginning to crumble and necessitating occasional repairs, it was decided to demolish the track and sell its lumber after the 1917 Independence Day event.
