Location

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.
