Chicago's "Mother River" - the Chicago River Chicago River is a 114-mile river that runs through the entire city of Chicago. Although the length is not particularly conspicuous, the river's civil engineering adds a lot to it. Today's Chicago River, sparkling, very pleasing, high-rise buildings on both sides of the river, walking on the bridge in Chicago may be able to see the most beautiful scenery. 900 years ago, the pollution of the Chicago River was very serious because it introduced the sewage from Chicago into Lake Michigan. In one of these sections, the river is red due to the relationship of the large slaughterhouse. Later, Chicago successfully reversed the flow of the Chicago River by constructing a series of sluice gates. The river has flowed into Lake Michigan and merged into the Illinois River to have the most beautiful Chicago River. Because there is the Chicago River, Chicago has become a city with a bridge. Every few steps, a tempered bridge passes directly through the Chicago River. These bridges are very old, basically built around 1900. The bridges are quite wide and they are very shaken on them. In the busy years of the Chicago River shipping, these tempered bridges are open and close. If you can meet the bridge of opening and closing, you are really lucky. It is said that a photographer once again waits for all the bridges on the Chicago River to open at the same time. What a rare opportunity to get a unique photo.
