Michigan Avenue Bridge

Of the 38 bridges spanning the Chicago River as it passes through the city of the same name, the most famous is undoubtedly the Michigan Avenue bridge. Not only was it one of the technical marvels of its time, but its construction marked the historic moment when Chicago began to spread northward. The extension of Michigan Avenue across the bridge meant the birth of the legendary stretch of earth known as the Magnificent Mile. Like other bridges in Chicago, Michigan Avenue can be shut down, although it is difficult to agree on a good time for this because you have to temporarily cut off one of the main arteries of the city).
