BRIDGE EXPANSION HANDLES ADDITIONAL TRAFFIC

A beautiful steel bridge spanning the Mississippi River, the 48-year-old Julien Dubuque Bridge, was economically strengthened and modified to handle heavier loads on a wider and safer roadway. The project included field inspection, widening of the deck, member strengthening, and strucural repairs. The details of the bridge renovation are described. The Service Load design Method was used in the analysis of the main truss members. The Strength Design Method (load factor) was used for girder spans and the floor system of the truss spans. Details of the truss and approach spans, and stringers are highlighted. The project required approximately 950 tons of new steel.
