From the Bridge Tender's Tower
A view out the round window of the historic Michigan Avenue Bridge over the Chicago River. The tower is open to the public, and is home to a new museum called The McCormick Tribune Bridgehouse & Chicago River Museum. It costs $3 to get in and look around at exhibits about Chicago's water supply and water transportation. You can even see the gears that help lift the bridge.
