The Margaret McDermott Bridge is a conventional concrete pier-and-beam freeway bridge[3] 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.[1] It was partially designed by Santiago Calatrava, and is part of the Trinity River Project and the Horseshoe Project.[1] It was named for Margaret McDermott, an area philanthropist.[2]
