The Margaret Hunt Hill Bridge is one of three[specify] Santiago Calatrava-designed bridges being built over the Trinity River in Dallas, Texas (USA) as part of the Trinity River Project.

History[edit]

Construction on the bridge began in spring 2007 with the steel being manufactured in an Italian steel factory often used by Calatrava to manufacture his designs. The factory made the steel for his Athens stadium.[1] It connects Spur 366 (Woodall Rodgers Freeway) in downtown to Singleton Boulevard in west Dallas. The cable-stayed bridge was expected to cost $93 million, its total length is 1,870 feet (570 m) with a main-span of 1,197 feet (365 m), and an apex-height of 400 feet (122 m).[2]

On Saturday, June 26, 2010, the signature, 40-story center-support-arch was topped-off with a central curved span, providing an additional feature to the Dallas skyline, as it can now be seen from many miles away from several directions.[3][4][5]

The bridge was officially lit in a special ceremony conducted by the City of Dallas and Mayor Mike Rawlings. While the bridge's opening was originally scheduled for March 2–4, 2012, and the Bridge Celebration scheduled for March 4, 2012, the actual opening was delayed to March 29, 2012.[6][7]

Popular culture[edit]

The bridge is featured in the opening credits of the 2012 version of the TV series Dallas.
