The Detroit International Riverfront includes a partially completed three-and-one-half mile riverfront promenade with a combination of parks, residential buildings, and commercial areas. It extends from Hart Plaza to the MacArthur Bridge accessing Belle Isle Park (the largest island park in a U.S. city). The riverfront includes Tri-Centennial State Park and Harbor, Michigan's first urban state park. The second phase is a two-mile (3 km) extension from Hart Plaza to the Ambassador Bridge for a total of five miles (8 km) of parkway from bridge to bridge. Civic planners envision that the pedestrian parks will stimulate residential redevelopment of riverfront properties condemned under eminent domain.
