Detroit River

The Detroit River is a river that flows along the USA-Canada border.

History
Marge crossed the Ambassador Bridge over the Detroit River to get to Canada to find Lisa. Later, Marge and Lisa crossed the frozen river to get back to America. They were then abandoned by their helpers when the ice started to crack. Homer and Bart came to rescue them in a truck, which then fell into the river. They then went to Detroit to get back to safety.
