The bridge's aesthetic qualities remain nearly unchanged, because our design retained the original aesthetics while significantly improving the load-capacity of the structure. Details to improve capacity and to provide structural redundancy included increasing the material strength and size of critical members and installation of catch plates, additional counters, and U-bolt hangers at key joint locations. Future maintenance concerns were addressed by galvanizing and painting all members, adding grease fittings to the pin connections, filling the grid deck with concrete over the abutment seats and over the beam flanges, and adding bent curb plates to direct runoff away from the truss bearings. We were responsible for project management, structural engineering, plan preparation, bid documents, specifications, shop drawing review, and construction services.
