The Margaret Hunt Hill Bridge is a bridge designed by Santiago Calatrava, which goes over the Trinity River in Dallas, Texas as part of the Trinity River Project. It is one of three such bridges planned to be built over the Trinity, though the other two lack funding and remain unbuilt as of June 2010. The span parallels the Continental Avenue Bridge, a walking bridge.

History[edit]

Construction on the bridge began in spring 2007 using steel from an Italian factory often used by Calatrava to manufacture his designs.[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, with a total length of 1,870 feet (570 m), a main span of 1,197 feet (365 m), and an apex height of 400 feet (122 m).[2]

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

The bridge was ceremonially lit at a special event conducted by the city and Mayor Mike Rawlings. While the bridge's opening was originally scheduled for March 2–4, 2012, and the celebration scheduled for March 4, the actual opening was delayed to March 29.[6][7]

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