From The Atlantic: Spectacular Photos of the East Side Access Project
I have mentioned this railroad connection project going on deep under NYC before, but here are some spectacular photos of the whole dig
The Tunnels of NYC's East Side Access Project
|
A huge public works project is currently under construction in New
York City, connecting Long Island to Manhattan's East Side. Deep
underground, rail tunnels are extending from Sunnyside, Queens, to a new
Long Island Rail Road terminal being excavated beneath Grand Central
Terminal. Construction began in 2007, with an estimated cost of $6.3
billion and completion date of 2013. Since then, the cost estimate has
been raised to $8.4 billion, and the completion date moved back to 2019.
When finished, the line will accommodate 24 trains per hour at peak
traffic, cutting down on commute times from Long Island, and opening up
access to John F. Kennedy International Airport from Manhattan's East
Side. Collected here are images of the progress to date, deep beneath
Queens and Manhattan. [33 photos]

caverns underneath Grand Central Terminal that will house a future
concourse for arriving and departing Long Island Rail Road trains. The
entire project is slated to be complete in 2019. (MTA/Patrick Cashin)
Work underway on one of the most challenging parts of the entire
project -- excavating a tunnel under Northern Boulevard, while
simultaneously supporting the overhead roadway, the overhead underground
subway, and the elevated subway. To ensure stability, the tunnel was
excavated in seven separate horizontal segments, or "drifts." And
because the ground is soft at this site and difficult to control during
excavation, it was frozen to allow for increased control and rigidity.
Workers had to drive a new set of foundation pilings into the ground to
temporarily support the elevated structure during construction. They
then jacked up the line a fraction of an inch to shift the weight to the
temporary supports, which you can see running vertically through the
newly built tunnel. Those supports will be removed after the weight of
the elevated subway is shifted back to the walls of the tunnel, which
has been engineered to carry the load. Photographed on December 20,
