From Dodge Wiki

Mound Road Engine was a Chrysler Corporation Automobile engine factory in Detroit, Michigan. The plant was closed by DaimlerChrysler in 2002, with production shifting to the Mack Avenue Engine Complex. The factory had been home to Chrysler's production of large-displacement V8 engine and V10 engine engines for 47 years.

The facility was torn down in late 2003 and the land paved over because it was cheaper to pay taxes on parking lot than an empty building. The newly paved area, as well as the old employee Parking lot, are now used to store vehicles that were manufactured at Warren Truck Assembly before shipping them to Car dealership.

Mount Elliott Tool and Die, another Chrysler facility, is located directly behind what used to be the Mound Road Engine plant.
