Project Description

I-70 Approach to Veterans Memorial Bridge Unit 3

TWM’s structural engineers prepared the curved girder erection plan for the Unit 3 segment of the direct approach to the new I-70 Mississippi River Bridge at St. Louis. This unit consists of 1,285’ long, 5-span dual structures with 9’ tall steel plate girders. TWM developed analytical models for curved structures for the stages of steel erection, using results to check strength, stability and deflections of the girders during lifting and at various stages of erection, developed temporary support and bracing details necessary for steel girder erection, and provided other structural support during construction.
