“Offering a major surprise, the City of Chicago on Friday will announce winners in its international design competition for pedestrian bridges along the lakefront, choosing a bold new look for the North Avenue Bridge instead of a plan that would have echoed the gently curving profile of the existing bridge.” Among the winners are a boomerang-shaped bridge with solar-powered lighting, two S-shaped specimens, and a curving suspension bridge. Each bridge will cost several million dollars to build, and construction is slated to begin in 2007.
