Monroe Street Bridge Replacement Design

McLaren was responsible for complete reconstruction design of the bridge, which was complex due to superstructure height limitation. The three-span structure was replaced with a single-span steel structure spanning approximately 72 feet. A finite element model of the entire superstructure was performed. Longitudinal stringers with moment connections were provided in addition to the thru-girders to share the loads. An elaborate construction staging scheme was performed to maintain three main tracks in operation at all times. Reconstruction was accomplished in multiple stages to minimize the impact on railroad traffic.
