The Addison Underbridge, now known as the RiverView Bridge, located in Chicago, IL is a 16-span, 1010-foot-long curved, concrete box girder pedestrian structure. Westbrook provided a peer review and construction engineering services for analysis of the Addison Underbridge structure. The longest span of the structure also featured a tight reverse curve, which required advanced analysis to evaluate the torsional stresses, bearing restraints for uplift, and long-term serviceability implication due to the torsional deflections. Additionally, Westbrook provided the design of the formwork and falsework system for the structure, including the camber diagrams for the reverse curves.
