Photograph on page 47 shows an
interesting example at 42d Street and Broadway, where the pressroom of
the new building of the "New York Times" is beneath the subway, the
first floor is above it, and the first basement is alongside of it.
Incidentally it should be noted that the steel structure of the
building and the subway are independent, the columns of the building
passing through the subway station.

At 42d Street and Park Avenue the road passes under the Hotel Belmont,
which necessitated the use of extra heavy steel girders and
foundations for the support of the hotel and reinforced subway
station. (See photograph on page 48.)
Along the east side of Park Row the ascending line of the "loop" was
built through the pressroom of the "New York Times" (the older
downtown building), and as the excavation was considerably below the
bottom of the foundation of the building, great care was necessary to
avoid any settlement. Instead of wood sheathing, steel channels were
driven and thoroughly braced, and construction proceeded without
disturbance of the building, which is very tall.
At 125th Street and Lenox Avenue one of the most complicated network
of subsurface structures was encountered. Street surface electric
lines with their conduits intersect. On the south side of 125th Street
were a 48-inch water main and a 6-inch water main, a 12-inch and two
10-inch gas pipes and a bank of electric light and power ducts.
