A few photos from today.
45th Street Station looking east
A bit further into the site
The crane that you see is actually on two tracks, and whenever there is material to be moved from one side of the site to the other (i.e. materials are delivered at the entrance to the site near the 45th Street roadway and are needed closer to where the orange tarps are), the whole crane is moved along the tracks. I tried to get a better picture of this in action but my batteries died in my camera.
Looking west from the 45th street roadway
The tracks will eventually be roughly where the brown gravel path is.
