Green Bay is an arm of Lake Michigan, located along the south coast of Michigan's Upper Peninsula and the east coast of Wisconsin. It is separated from the rest of the lake by the Door Peninsula in Wisconsin, the Garden Peninsula in Michigan, and the chain of islands between them, all formed by the Niagara Escarpment. Green Bay is some 120 miles (193 km) long, with a width ranging from about 10 miles (16 km) to 20 mi (32 km). It is 1,626 square miles (4,210 km2) in area.
At the southern end of the bay is the city of Green Bay, Wisconsin, where the Fox River enters the bay. The Leo Frigo Memorial Bridge (formerly known as the Tower Drive bridge) spans the point where the bay ends and the Fox River begins. Locally, the bay is often called the Bay of Green Bay to distinguish the bay from the city. The bay is navigable by large ships.
