Martin/Martin teamed with fabricator Zimmerman Metals to provide RTD with a 204-foot single span steel pedestrian truss bridge. The bridge provides access across US 36 adjacent to the University of Colorado Boulder campus. The architecturally striking structure is composed of hollow structural section tubes and has a glass façade, metal roof, and window overhangs. We completed steel design utilizing robust 3D modeling software.
