DISCUSSION ON NEW YORK SUBWAY.
[Minutes of
Mr. Fitz- Sir George Gibb, namely, that the natural configuration of Manhattan
’Island rendered it a place where railways were bound to obtain traffic
to almost any extent, whatever kind of locomotion was adopted.
Manhattan was a long, narrow island 14 miles in length and 13 mile
broad, and consequently nine-tenths of the traffic was in a north and
south direction. According to the Paper, the population of Manhattan
Island was 2,200,000, spread over an area of 21 square miles, as com-
pared with the population of London, nearly 5,000,000, spread over
an area of 121 square miles. Manhattan thus had an enormous
population per acre to draw upon for any kind of locomotion, quite
apart from the large numbers of persons who entered it every day
from outside areas. Out of curiosity he had attempted to discover
the most densely populated 21 square miles in London, and the most
he could get was 1,300,000 to compare with 2,200,000 in New York.
One of the first points of difference to which he wished to draw atten-
tion was the width of streets in New York. He did not think it was
quite realized what the width of streets meant to those who were
making subways. Taking the New York streets under which the
Subway was made, and beginning at the south end of the Subway, the
width of Broadway at that point was 80 feet; further on, in Elm
Street, there was also a width of 80 feet ; in Lafayette Place there was
a width of 100 feet ; in Fourth Avenue there was 100 feet increasing
to 150 feet; crossing over from Fourth Avenue into Broadway,
through Forty-second Street, there was a minimum width of 90 feet;
the upper part of Broadway began with a width of 100 feet and
increased to 150 feet. Such streets were not to be found in London;
it was possible to count on one’s fingers the streets in London which
were 80 feet wide, and as far as he knew there were only three streets
in London 100 feet wide, Whitehall, Whitechapel Road, and Kings-
way. It was interesting to consider for a moment the construction
of subways in wide streets as compared with narrow streets. First,
there was of course the great facility afforded for construction by
enabling cranes, materials, etc., to be brought alongside the work.
Then, room for stations could be found under the streets, doing away
with the necessity of acquiring property ; and there was ample room
for access from the streets to the stations—a matter which those who
have been engaged in making subways in London found extremely
difficult and expensive to arrange for. There were also facilities
for dealing with pipes and sewers. People hardly realized what
difficulties there were in dealing with a number of pipes, unless
they had to do it. He had had to carry out such work in narrow
streets and had found that while it was quite easy to take the pipes
out it was very difficult to find any place to put them in again. In
