Michigan Avenue Bridge, also known as Du Sable Bridge, was Chicago's earliest immigrant settler. The bridge over a hundred meters long was not noticeable, but it was in such a place. At both ends of Michigan Street Bridge and along the Chicago River, it is a paradise for architects to show their talents. They really regard the building as an artistic creation and compete for new ideas. Standing on the Michigan Street Bridge, they can see the Spanish Gothic style, classical style, Renaissance style and modernist style everywhere. The Arrow Tower and the Chicago Forum Building are opposite to each other. It has become a rare urban bridge in the world. High-rise buildings are dense, but there is no sense of hesitation and depression; different styles, but complement each other. The north bank under the bridge is a cruise ship wharf, and the south bank under the bridge is a Chicago Riverside Walk.
