• Resumen

  • The Margaret Hunt Hill Bridge, designed by Spanish architect Santiago Calatrava, is a cable-stayed bridge over the Trinity River in Dallas TX. The roadway, almost 1200 ft. long, is supported by fifty-eight cables, twenty-nine on each side of the central arch, strung from the arch to the traffic median between the lanes going east or west. The bridge first opened to vehicular traffic in Mar 2012 and has already been hailed as an icon of twenty-first-century Dallas. Here, Wilcock presents mathematical problems about the bridge.
