The designer of the bridge was Polish-American engineer Ralph Modjeski. Contractors included C. Macdonald &amp; Co. of New York, J.S. Paterson Construction Company of Chicago, MacArthur Brothers of Chicago, and American Bridge Company of New York. The American Bridge Company in turn subcontracted the superstructure's erection to Kelley-Atkinson Construction Co of Chicago.
