Lighting the bridge meant finding a way to integrate fixtures into an already minimal structural frame. Illuminated pathways at the deck level provide wayfinding for cyclists and pedestrians, respectively, while custom-length cathode light strips with opaque acrylic sleeves above form continuous lines of light. “The challenge was mostly from [Calatrava’s] office, in that they had this unusual length the lighting had to span, so we made custom fixtures,” says Steve Grossman, president of Cathode Lighting Systems, the Maryland-based company that fabricated the 14-foot luminaires. “There is steplighting below, but this was more of a decorative line of light, not driven by footcandle requirements, with segments of that lighting that go from one structural beam to the other.”
