Sorry, Mound Road engine plant was just across the street from the truck plant...

Mound Road engine plant was at 8 Mile and Mound road south of 8 Mile, and Warren Truck Assembly plant was at 8 Mile and Mound road north of 8 Mile...
Yes, those plants were closer, like 1/2 to 3/4 mile apart. Was just taking a guess from memory. Ask the mailman: Ex. Address of (21000 Mound Road minus 5000) ÷ 2 = 8,000 = 8 Mile Road and Mound Road, center of intersection. (19000 Mound Road minus 5000) ÷ 2 = 7,000 = 7 Mile Road and Mound Road. Each mile 2000 in address.
Mound Road Engine Plant, 20300 Mound Rd., so about 7.65. Warren Truck Assembly Plant #1, 2452, 21500 Mound Rd. So 8.25 miles, North of Detroit. These are locations of the entrances to the plant, I believe, so theoretically the Plants could extend to a "corner". In fact, WTAP #1 was extended closer to 8 Mile around 1980, with a new paint building, and the engine assembly lines/loops moved to a separate building South of the Main building.
