"This bridge was the first Chicago bascule bridge to have a smoothly-curved pony truss design for a movable bridge, and was the generation of trunnion bascule bridges that succeeded the somewhat clunky looking bridge design seen on bridges such as Grand Avenue. The Monroe Street Bridge however still has the clunky looking detail at the ends of the trusses like the Grand Avenue type bascules. Later examples of this bridge design would have a more aesthetically pleasing curved detail at the ends in addition to the smoothly curved detail in the center. The Franklin Street Bridge is one such later example." [HistoricBridges]

This photo motivated these notes. But after doing a little research, the bridge in this photo is two blocks south on Adams Street.
