The artist and design team were inspired by the bridge's nearby mountains to develop a structure resembling a jagged rock outcropping. Spanning ten lanes of depressed freeway, the bridge consists of a post-tensioned superstructure supported by a cast-in-place median pier and abutments. The stair-stepped pier and abutments suggest abstracted mountain forms and southwestern architecture. Scuri used tire treads to cast relief patterns resembling cactus skin and Native American basket on the adjacent freeway walls -- acknowledging the role automobiles have played in defining Phoenix's urban landscape.
The perforated and expanded metal screening of the bridge's safety enclosure form a shaded walkway. The red tone of the bridge and adjoining walls reflect the mercury once mined at the site, and the red-tiled roofs in surrounding neighborhoods.
