Midtown, 1935. St. Louis developed a couple downtown-like nodes, presenting a fairly heavy corridor of development from the river to Forest Park. This is about 3 miles from the river.
Downtown, Union Station, 1924. Union Station St. Louis. When Union Station was opened in 1894, it was the largest and busiest single station in the world.
