Green River Ordnance Plant

The Green River Ordnance Plant, also known as the Green River Arsenal, was a large munitions factory complex between Dixon and Amboy in Lee County, Illinois.

It was rapidly constructed in 1942 and just as quickly shut down in 1945. Stewart-Warner Corporation operated the complex to produce rocket-propelled bazooka ammunition, artillery shells, naval shells, bombs, rifle grenades, fuses and rockets for use during World War II. 

It lies on the south side of U.S. Highway 30.
