World Walk turns a pedestrian bridge into an immersive atlas in San Antonio, Texas. The bridge becomes a walk around the world, covering 24,900 miles of vast and disparate regions of the globe as a map permanently etched across the entire concrete bridge span. Colored steel tabs are permanently affixed to the existing chain link and highlight corresponding climactic zones, while special steel tabs developed in collaboration with local area public school students are etched with a myriad of corresponding geographical subjects and information.
