91st, NE corner - looking N
Most work at the moment seems to be focused on the blocks between 91st and 93rd streets. The plan, at the moment, is to move the work site back to the west side of the 2nd Avenue on July 14th.

The sections of pipes shown (each either 30" or 42" in diameter) are for a new gas main.

This special concrete mold was laid in the past few days.

Further north on 2nd Avenue the contractors have now closed up the street and they've installed a new sidewalk, as you can see.

But, near the intersection, it looks like there's still quite a bit of work to do relocating various utility lines.

This wooden deck was put in to provide access over an open trench near a building on 2nd Avenue. The deck allows people to access the shops and apartments while the trench is open.

And a little farther north the utility relocation work has progressed far enough that the sidewalk can now be relaid.

This is a protected walking path to one of the shops between 93rd and 94th.

The numerous concrete boxes in the middle of the walking path, I believe, provide access to the "splice boxes" for the beams that will be installed to support the deck surface.

The pedestrian walking path here is right down the middle of 2nd Avenue, to the left of the Jersey Barrier. Access to the shops and buildings is provided via walkways that sort of look like small pedestrian alleys. Note the small square signs that have been posted at the head of each alley.

This brand new German made Liebherr HS 855 crawler crane appeared on the site about 10 days ago, up near 95th street.

I believe that the tan colored piece on equipment on the right is known as a "slurry wall clamshell grab." At this location they will be using it to dig the trench for the north bulkhead of the Launch Box. This link gives a good overview of how slurry walls are built.
