Artist Beth Galston worked with the BRW engineering team to transform the appearance and structure of the freeway underpass from a square concrete culvert with 24-foot high walls facing nearby homes into one with rounded walls and more graceful form. The corner columns were rounded and exposed to “lift" the structure and create the feeling of a gateway. She added serpentine terraced walls with curving metal railings to further soften the structure. The bridge's curved form was designed to be dramatized by a special lighting system, including blue lights on the front of the corner columns and yellow back-lighting.
A sculpted landscape of earth mounds and contours extend for several hundred feet on all four sides. The mounds echo the outlines of nearby hills and Piestewa Peak, to the south, and pay homage to ancient Native American cultures that thrived nearby.
