From NGA Office of Corporate Communications:
Peek through cracks in the fence surrounding the National Geospatial-Intelligence Agency’s new facility site in North St. Louis, and you can catch a glimpse of yellow-clawed machines digging. All that dirt-moving is part of the City of St. Louis’ preparations for the construction of NGA’s new campus in 2021.
This is the second dig the city has commissioned on the site. The first: an archeological excavation to record the history of the 27 urban blocks contained in future NGA site.
