The Michigan Avenue Bridge, built just to the east of the swing bridge at Rush Street, was in the modern trunnion bascule style. A double deck sent commercial traffic to a lower level connected to improvements at Wacker Drive. The bridge was an integral part of the improvements presented in the 1909 Plan of Chicago by Daniel Burnham and Edward Bennett. When completed in 1920, the Rush Street Bridge was quickly removed (and with it one of the last vestiges of nineteenth century bridge-building). This photograph of the bridge was taken from an upper floor of the Tribune Tower.
