The Margaret Hunt Hill Bridge is a bridge in Dallas, Texas which spans the Trinity River and was built as part of the Trinity River Project. Designed by Santiago Calatrava, it is one of three such bridges planned to be built over the Trinity; the second, the Margaret McDermott Bridge, is currently under construction. The span parallels the Ronald Kirk Avenue Bridge, a walking bridge.

The bridge is named for Margaret Hunt Hill, an heiress and philanthropist.[3]

History

Construction on the bridge began in spring 2007.[4] It connects Spur 366 (Woodall Rodgers Freeway) in downtown to Singleton Boulevard in West Dallas. The cable-stayed bridge cost $117 million to build, 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).[5] A Dallas Morning News analysis puts the project's total cost at $182 million.[6]

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.[7][8][9]
