The Margaret McDermott Bridge is a conventional concrete pier-and-beam freeway bridge with cable-stayed bike lines over the Trinity River in Dallas, Texas. It replaced the late-1950s to early-1960s Interstate 30 (I-30) bridge, which reached its end of life. It was partially designed by Santiago Calatrava, and is part of the Trinity River Project and the Horseshoe Project. It was named for Margaret McDermott, an area philanthropist.

Margaret McDermott Bridge in the context of Margaret Hunt Hill Bridge
The Margaret Hunt Hill Bridge is a cable-stayed bridge in Dallas, Texas, that spans the Trinity River. The bridge is named for Margaret Hunt Hill, an heiress and philanthropist. The bridge was constructed 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 completed; the third cancelled. The span parallels the Ronald Kirk Bridge, a walking bridge that was previously the Continental Avenue bridge.
