Bixby Creek Bridge, on Hwy 1 along the Big Sur coast, is one of the most photographed bridges in California due to its aesthetic design, "graceful architecture and magnificent setting." It is a reinforced concrete open-spandrel arch bridge 13 miles (21 km) south of Carmel in Monterey County. 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 (18 km) inland. At its completion, the bridge was built under budget for $199,861 (equivalent to $3.5 million in 2015) and was the longest concrete arch span at 360 feet (110 m) on the California State Highway System. It is one of the tallest single-span concrete bridges in the world. en.wikipedia.org/wiki/Bixby_Creek_Bridge
