The River Bridge Tower along the Milwaukee Riverwalk in downtown. The Riverwalk is a 20-block pedestrian promenade along the Milwaukee River. There are two skybridges visible in this photo, part of the Milwaukee Skywalk System, affectionately referred to as "Skywaukee". Downtown is peppered with nine such skybridges spanning a skywalk of 1.75 miles (2.8 km), which encourages pedestrian traffic throughout the downtown area during the winter's heavy weather.
