The Greentown Federal Building is a complex to house many departments of Federal Government. It was once a crowded place upon its operation commencement. However, it was designed to fail the convenience for car drivers because of the extremely limited parking lot in & surrounding the complex. Later on, many departments moved out from this complex to their own building elsewhere and leaving here almost an empty shell, while those additional buildings are built big and beautiful with taxpayers' money. The corridor of Greentown Federal Building, once flooded by civilian, is now quiet.
