The city, together with the Riverfront Conservancy, undertook another major project planned at $559-million along the Detroit International Riverfront to construct a three-mile (5 km) riverfront promenade park along the east river from Hart Plaza and the Renaissance Center to the Belle Isle bridge. Detroit Wayne County Port Authority added the Dock of Detroit (2005), a state of the art cruise ship dock on Hart Plaza near the Renaissance Center. A two-mile (3 km) extension along the west river will take the riverfront promenade park from Hart Plaza to the Ambassador Bridge (1929) for a total of five miles (8 km) of parkway from bridge to bridge. Michigan constructed its first urban state park, the William G. Milliken State Park and Harbor (2003). Three contemporary high-rise casino resort hotels in Detroit include the MGM Grand Detroit (2007) by SmithGroup, Motor City Casino (2007), and the 30-story Greektown Casino (2009). A fourth contemporary high-rise casino resort hotel, Caesars Windsor (1998/2008), is visible from the International Riverfront.
