Ground Zero: Retaining Wall

---

In New York City, this is the eastern retaining wall (also known as a slurry wall), adjacent to the area where the south tower of the World Trade Center (WTC 2) once stood. The wall was built to help keep the Hudson River from flooding the 7-story basement area below the twin towers. The wall is 3 foot thick, 100 foot deep, and is socketed into bedrock with cables attached with tiebacks.
