To build foundations in the wet soil adjacent to the Hudson River, engineers constructed a 3,500-foot-long concrete underground "bathtub". This prevented the Hudson from flooding the excavation site and became a marvel of civil engineering. IV. Economic Symbiosis and the Globalized City
The Port Authority razed 16 acres of active, small-scale industrial and electronic shops (the famous "Radio Row") to create a singular massive superblock. This permanently de-mapped several historical streets, detaching the complex from the traditional Manhattan street grid. World trade center and manhattan 1:2
