e Brooklyn Extension connects near Broadway and Park
Row with the Manhattan Bronx Route and extends under Broadway, Bowling
Green, State Street, Battery Park, Whitehall Street, and South Street
to and under the East River to Brooklyn at the foot of Joralemon
Street, thence under Joralemon Street, Fulton Street, and Flatbush
Avenue to Atlantic Avenue, connecting with the Brooklyn tunnel of the
Long Island Railroad at that point. There is a loop under Battery Park
beginning at Bridge Street. The length of this route is about 3 miles.

The routes in Manhattan and The Bronx may therefore be said to roughly
resemble the letter Y with the base at the southern extremity of
Manhattan Island, the fork at 103d Street and Broadway, the terminus
of the westerly or Fort George branch of the fork just beyond Spuyten
Duyvil Creek, the terminus of the easterly or Bronx Park branch at
Bronx Park.

[Sidenote: _Location

The stations beginning at the base of the Y and following the route up
to the fork are located at the following points:
