It looks like the Sands Street gate, the entryway into the Navy Yard, is nearly complete. The tower on the west side (pictured) is almost finished and the tower on the east side just started going up. This project has been in the works since 2009, when construction workers removed the wooden structure that covered the original gatehouse. Since then the Brooklyn Navy Yard has been restoring the brick and marble design back to its original splendor.
