Significance: The Lake Shore & Michigan Southern Railway's two parallel vertical-lift spans over the Calumet River, and two neighboring spans built by the Pittsburgh, Fort Wayne & Chicago Railway (of which one survives), are the largest multiple installation of Waddell and Harrington's patented design. Differences between the two pairs of bridges demonstrate disparity among American railroads' building codes, as well as Waddell and Harrington's refinement of the vertical-lift form. This site's many bridges built in close proximity is an artifact of intense competition among trunk lines entering Chicago from the east, and perhaps the greatest physical monument to the railroad capital of North America.
