“ Illinois is more immediately affected by the bridges over the Chicago river and its branches than any other state, and is more directly concerned for the prosperity of the city of Chicago, for the convenience and comfort of its inhabitants, and the growth of its commerce. And nowhere could the power to control the bridges in that city, their construction, form, and strength, and the size of their draws, and the manner and times of using them, be better vested than with the state, or the authorities of the city upon whom it has devolved that duty. ”
