m as nearly as possible to the views of the Court,
the Commission proposed, in 1897, the so called "Elm Street route,"
the plan finally adopted, which reached from the territory near the
General Post-office, the City Hall, and Brooklyn Bridge Terminal to
Kingsbridge and the station of the New York & Putnam Railroad on the
upper west side, and to Bronx Park on the upper east side of the city,
touching the Grand Central Depot at 42d Street.

Subsequently, by the adoption of the Brooklyn Extension, the line was
extended down Broadway to the southern extremity of Manhattan Island,
thence under the East River to Brooklyn.

The routes in detail are as follows:

_Manhattan-Bronx
Route_]

Beginning near the intersection of Broadway and Park Row, one of the
routes of the railroad extends under Park Row, Center Street, New Elm
Street, Elm Street, Lafayette Place, Fourth Avenue (beginning at Astor
Place), Park Avenue, 42d Street, and Broadway to 125th Street, where
it passes over Broadway by viaduct to 133d Street, thence under
Broadway again to and under Eleventh Avenue to Fort George, where it
comes to the surface again at Dyckman Street and continues by viaduct
over Naegle Avenue, Amsterdam Avenue, and Broadway to Bailey Avenue,
at the Kingsbridge station of the New York & Putnam Railroad, crossing
the Harlem Ship Canal on a double-deck drawbridge. The length of this
route is 13.50 miles, of which about 2 miles are on viaduct.

Another route begins at Broadway near 103d Street and extends under
104th Street and the upper part of Central Park to and under Lenox
Avenue to 142d Street, thence curving to the east to and under the
Harlem River at about 145th Street, thence from the river to and
under East 149th Street to a point near Third Avenue, thence by
viaduct beginning at Brook Avenue over Westchester Avenue, the
Southern Boulevard and the Boston Road to Bronx Park. The length of
this route is about 6.97 miles, of which about 3 miles are on viaduct.

At the City Hall there is a loop under the Park. From 142d Street
there is a spur north under Lenox Avenue to 148th Street. There is a
spur at Westchester and Third Avenues connecting by viaduct the
Manhattan Elevated Railway Division of Interborough Rapid Transit
Company with the viaduct of the subway at or near St. Ann's Avenue.
