The Galena Creek Bridge is a twin-span concrete arch bridge in Washoe County, Nevada. The bridge carries Interstate 580 and U.S. Route 395 over the Galena Creek[1] between Carson City and Reno. It was opened to traffic in late August 2012.[2]

The bridge has a total length of 1,725 feet (526 m) and main span length of 689 feet (210 m).[3] The height is 295 feet (90 m).[4] The bridge is reportedly the largest cathedral arch bridge in the world; that is a type of open-spandrel deck arch bridge where the arch supports the deck only at the center.[3]

Construction was started in 2003 but was delayed by a number of safety concerns and other issues. In 2006, the original prime contractor found the planned construction method unsafe; the method was revised and a new contractor hired.[2][3] In 2010, several long superficial cracks were found.[5] On July 28, 2012, the Nevada Department of Transportation held a community event for pedestrian, bicycle, and limited motor vehicle traffic to see the bridge prior to it opening for traffic; the bridge and freeway project opened in late August 2012.[6]
