Per Chuck Sudo of the Chicagoist, the Division Street Bridge lost its race to collapse before being repaired…
Starting Monday crews will begin demolishing Division Street Bridge near Goose Island. The city will be replacing the 111-year-old Bascule Bridge with an interim span while building a permanent Bascule replacement. The bridge was originally built in 1903 and has served as an integral link across Goose Island for cars, bikes, pedestrians and trains over the years, but currently isn’t wide enough to accommodate the size and flow of modern traffic. The Division Street Bridge is one of several Bascule bridges that made the Landmarks Preservation Council of Illinois’ 2013 list of the 10 most endangered historic places in the state.

Per Historic Bridges, this bridge was last rehabbed in 1992, but as these photos demonstrate, the bridge is a little rickety.
Circumstantial Evidence – Panatomic X
Crossing the North Branch Chicago River Canal onto or off of Goose Island, this is one of the very first highway bascule bridges built in Chicago, constructed just a couple years after Cortland Street. Given the influence that Chicago’s development of the bascule bridge had on bridge construction nationwide, this prototypical example of a Chicago type trunnion bascule bridge is nationally significant and its preservation should be given a paramount level of priority.
Roemheld & Gallery of Chicago were both the designers and builders of the bridge. This bridge is similar to bridges like Cortland Street, but it has one very unusual and distinctive characteristic which sets it aside from these other bridges. The overhead sway/portal bracing for this bridge is composed of simple plate steel with decorative designs on them that includes an upside-down “Y” design with a circle around it that is used in Chicago to refer to the three branches of the Chicago River. The symbol became an officially designated symbol appearing in Chicago’s municipal code as the “Municipal Device.” Easy to miss unless you are looking for it, the symbol can be found on buildings and structures throughout the city including on a few other bridges. This Division Street Bridge however is the only bridge in the entire city that includes this design in its overhead bracing. The bridge is different from the other early bascule bridges including the bascule bridge in sight of this one also on Division Street, which have a more intricate network of built-up sections of v-laced and latticed steel for bracing. The plates with the Municipal Device symbol on this bridge are an interesting and decorative element that adds a lot to the bridge.
