Wow-- things are really changing fast up on the Highline. Since we last visited a couple of weeks ago, new benches have been installed, and holes seem to have been cut for new stairwells leading down to the street. The entire platform bed south of 30th Street has been cleared of brush and coated with a new layer of concrete, giving the rail-bed an eerie surface-of-the-moon look. The buildings along the line have also grown-- especially the new Standard Hotel near 12th Street.
