Lots of Progress at 86th Street

Patrick Cashin, one of the MTA's staff photographers, captured a nice set of images of the 86th Street station cavern earlier this month. As the images below clearly show, there has been a lot of progress underground at this location.

I believe that this is a view of the south end of the cavern. The two tunnels, which were excavated by the tunnel boring machine in 2010 and 2011, are partially hidden from view in this image.

In this image the photographer is standing at (under) the northwest corner of 86th Street and Second Avenue.  This corner is the future location of Ancillary No. 2 for this station.

The photographer is now standing at (under) the northwest corner of 83rd Street and Second Avenue. This street corner is the future location of Ancillary No. 1 for the this station.

The duct work on the roof is part is part of the air handling system.  I believe that one of the ducts is used to provide fresh air for the cavern and the other duct is connected to the air scrubber unit at this corner. (The scrubber unit, which is at street level, is used to remove dust and other particles from the air before it is exhausted into the open air.)

An interesting video of blasting operations, from street level, near 86th Street. The video also shows how the rock is transported out of the cavern.
