Rib arch bridge
WebbA through arch bridge, also known as a half-through arch bridge and through-type arch bridge, is a bridge made from materials such as steel or reinforced concrete in which the base of an arch structure is below the deck, but the top rises above it, so the deck passes through the arch. Webb* Each arch rib is made up of 56 cast-in-place sections with construction starting from the canyon walls and a closure pour that locks the two halves together. A majestic showcase: the new Hoover Dam bridge reaffirms that American engineering can build great infrastructure despite the current economic challenges
