Pictured above are five draw bridges, located in downtown Chicago, spanning parallel across the Chicago river. Draw bridges are very important because they allow vessels to pass that would not be able to pass through a water way with a fixed bridge. Along this section of the Chicago river there are approximately two dozen draw and bascule bridges to allow the busy city street traffic and river traffic to coexist.
