The problem with redevelopment was that Milwaukee in the past simply hid this area by building bridges that completely spanned the Menomonee River Valley. People drove over it never giving it a second look. What was needed was to replace these overpasses with a new road system that tied the river valley into the rest of the city.
The first chance came with the replacement of the 6th Street Viaduct. The old structure was at the end of its life. It was replaced with a set of signature bridges consisting of two cable stayed spans and two draw spans. The structures cross two river channels and three main rail lines. The result is that 6th Street now crosses the north cable stayed span to cross two rail lines and drop into the valley, then crosses the two river channels on draw bridges, and climbs back out of the valley crossing the final rail line on the second cable stay span. By bringing the road down in to the valley, redevelopment of the older industrial sites has hit high gear. Old railroad warehouses are now highly sought after loft spaces or commercial office space. This is a great example of how the right bridges can tie a community together and spur positive development. In fact, Harley Davidson was so impressed with the area that they are building their motorcycle museum on this river crossing between the two river channels.
The structure on this page is the southern cable stay span. It crosses a very busy double track rail line, ending in a traffic circle.
