Illinois and Michigan Canal Museum: (IL) At a stroke, the opening of the Illinois and Michigan Canal in 1848 gave Illinois the key to mastery of the American mid-continent. The dream of the canal had animated every vision and underlaid every plan for Illinois for 200 years before. As that vision was realized, the canal's commissioners laid out a canal port that would grow into a great metropolis. And their fellow citizens patented agricultural and industrial innovations that would make this the richest economic zone the world had ever seen. That Illinois is now the most populous inland American state, and Chicago the greatest city of the American heartland, are directly traceable to the 97-mile ditch that linked the Great Lakes to the Illinois and Mississippi rivers.Mississippi River Visitor Center: (IL) The Mississippi River Visitor's Center is located on the Rock Island Arsenal in Rock Island, Illinois at Lock and Dam 15 , overlooking the Upper Mississippi River.
