Ciénega Bridge is an open-spandrel arch bridge which crosses Pantano Wash near Vail, Arizona.[1] Construction was started in 1920 by the Arizona Highway Department. The Highway Department received financial aid from the federal government as well as Pima and Cochise counties. The bridge was completed in 1921 at a total cost of $40,000.[2] Starting in 1926, the bridge carried U.S. Route 80, a transcontinental highway which stretched from Tybee Island, Georgia to San Diego, California.[3][2] In 1956, US 80 was rerouted to a new route south of the bridge.[4] US 80 was replaced by Interstate 10 in 1977.[3] The Ciénega Bridge was added to the National Register of Historic Places on September 30, 1988.[1] The bridge along with Marsh Station Road was designated as part of Historic U.S. Route 80 by the Arizona Department of Transportation on September 21, 2018.[5]
