Description 

TxDOT selected an extradosed bridge which is a hybrid structure that combines elements of a steel box girder, reinforced concrete deck and cable-supported superstructure. Although fairly common in other countries, extradosed bridges are rare in the United States. It is the first extradosed bridge in the United States using a steel composite superstructure, which adds an extra complexity in maintaining the stay forces during construction. The construction engineering loads are shared between girder and stays, with the stays acting more as external post-tensioning rather than a vertical support. Steel beams work in conjunction with pylons anchored by shallow-angled cables which carry between 20% and 30% of the bridge load. - See more at: http://www.finleyengineeringgroup.com/projects/project.cfm?a...
