Chrysler Jefferson North Assembly Plant, Michigan

This assembly plant opened in 1991, and is said to be the only assembly plant that is completely inside the city limits of Detroit. It was built on the site of a Hudson Motor Company plant, to make the Jeep Grand Cherokee, which it still does, along with the Dodge Durango. The plant has around 3,000,000 square feet. It is one of five remaining assembly plants in the USA operated by Chrysler (now Fiat Chrysler).
