In page Bixby Creek Bridge:

"

The bridge was completed on October 15, 1932,[1] although the highway was not finished for another five years. At its completion, the bridge cost $199,861 and, at 360 feet (110 m), was the longest concrete arch span on the California State Highway System.[4] The bridge was necessary to complete the two-lane road which opened in 1937 after 18 years of construction.[5] The completion of construction was celebrated with a ribbon-cutting ceremony led by Dr. John L.D. Roberts, who had conceived of the need for the road.[6]
