Old Subway Maps

http://www.onnyturf.com/subway/ is a subway map/google map mashup that
newly lists subway station layouts.

You'll note in this map of the 125th St ABCD IND station the existence
of a southwest exit at the corner of 124th st & Hancock Pl.

subway stuff

This exit does not exist any longer.

You can however, make out the outlines of a previous staircase opening
in the ceiling of both the southern parts of the north and southbound
subway platforms.

That entrance would have been in a now dark block, and from the large
police presence on 125th st, I can see the security justifications of
removing that entrance.

One can wonder if the that block was blighted before the removal of
that entrance, and if that block would be considered further blighted
after the removal of the entrance.
