Milwaukee

The evolution of state and regional transportation agencies is painfully slow in places like Missouri and Ohio, where officials are plowing ahead with pricey highway projects conceived of decades ago. But plenty of Midwesterners have different ideas for the future of their communities, and they aren't shy about speaking up.

As mayor of Milwaukee from 1988 to 2004, CNU President John Norquist made urbanism and livability top priorities. Some of his most notable achievements centered on the redevelopment of highway corridors with street grids and infill, culminating with the demolition of the Park East Freeway in 2002 -- one of the largest voluntary highway removal projects undertaken in America. Other projects, like the introduction of a light rail system, never reached fruition.
