Teresa Villegas's colorful floor features 13 distinct terrazzo colors and flowing lines made of 3/8-inch aluminum strips cut by waterjet. To capture the sparkle of natural light pouring through the western windows, she used white shell, and clear and mirrored glass in the terrazzo aggregate. The floor's detailed patterns and shapes were designed not to be seen at once, but gradually, at the pace of a leisurely walk across the bridge. Villegas worked closely with the PHX Sky Train design and construction team to integrate the terrazzo into the bridge.
