Significance: The first Monroe Street Viaduct was built in 1913 to carry vehicular traffic across the sunken railroad tracks that slice through Grant Park on Chicago's lakefront. By the 1930's, this bridge was deemed to narrow to accommodate Chicago's increasing automobile traffic, and plans were made to replace it with a longer, wider structure. The straightforward steel girder and beam design that featured a subtle Art Deco architectural treatment for the approaches, lighting, rails, and ornamental fascia, reflecting an ongoing architectural transition in the city's bridges away from the Beaux Arts classicism that dominated earlier structures.
