Thought you would be interested in this, Ford build Willow Run Ariport and I-94(it was not called I-94 ) but was built for the workers to get there.
A Bit of World War II History.
Willow Run is near Bellville, Canton and Ypsilanti, Michigan.
It's amazing that one B-24, with over a million parts, came off the assembly line every 55 minutes.
This is a great snapshot of history, a tribute to the greatest generation and American industrial power.
