Unveiled in 1988, the Hixon bridge was influenced by German philosopher Martin Heidegger, Armajani explained in an interview last week. Heidegger had a theory that illuminates the thinking behind the bridge, with eight lanes of highway running below. The traffic is as relevant to the experience as the sky above and the couple stopping to snap photos before traveling along. “Heidegger says that ‘a bridge is an entity which brings whatever it is before the bridge to what is after the bridge, in addition to what it brings from above the bridge, and what is below the bridge,’” Armajani said.
