Luis G. Gutierrez–Cushing Street Bridge
Structural Design Tucson, Arizona
The Luis G. Gutierrez-Cushing Street Bridge celebrates the reunification, both socially and physically, of Tucson’s west side communities and downtown area. This iconic structure, which is the first multi-modal (modern streetcar, vehicular, bicycle and pedestrian) public works project in Arizona, creates a destination and attraction as well as a critical linkage for parts of Tucson that were previously isolated. The bridge is built with the longest precast AASHTO girders ever cast in Arizona and sits on the longest drilled shafts ever used for an AASHTO girder bridge in Arizona. Complex architectural and artistic features are incorporated including steps from the deck sidewalks to the multi-use path below at all four corners of the bridge; bridge, step and wall railings made of pre-cast concrete and designed to replicate historic balusters; design, fabrication and erection of structural shade canopies over the promenades; and the incorporation of 12 local historically significant events in the shade structures and sidewalk deck creating an interactive experience for the visitor.
