Bixby Bridge in Big Sur California

Bixby Creek Bridge, also known as Bixby Bridge, is a reinforced concrete open-spandrel arch bridge in Big Sur, California. The bridge is located 120 miles  south of San Francisco and 13 miles  south of Carmel in Monterey County along State Route 1. Prior to the opening of the bridge in 1932, residents of the Big Sur area were virtually cut off during winter due to the often impassable Old Coast Road that led 11 miles  inland. At its completion, the bridge was built under budget for $199,861 and was the longest concrete arch span at 320 feet  on the California State Highway System.   Source
