"A dramatic new concrete arch joins the setting of the historic Hoover Dam, spanning the Black Canyon between the States of Arizona and Nevada, USA. This 1060 foot long arch span is the 4th longest concrete arch in the world, and the longest in the United States. The superstructure is a composite deck system using steel box girders and a conventionally reinforced concrete deck, integral with pier caps, which serves as the lateral bracing system for the bridge. The scale of concrete construction for the bridge was impressive. Four form travelers advanced to the crown of the cast-in-place arch supported by 88 carefully tuned stay cables, while precast segmental construction was used for the tallest precast columns erected to date." text source: (
