State Street Bridge and Marina Towers, Chicago

The State Street Bridge spans the Chicago River in downtown Chicago, connecting the Loop to the Near North Side. Completed in 1949, this bascule bridge replaced an earlier structure and is a vital artery for vehicular and pedestrian traffic. To the west, the distinctive Marina City towers, designed by Bertrand Goldberg and completed in 1964, rise above the riverfront. These mixed-use buildings, with their unique cylindrical design, were a pioneering development in urban living and remain a prominent feature of the Chicago skyline.
