New York State Route 9A
Encyclopedia
New York State Route 9A (NY 9A) is a state highway
in the vicinity of New York City
, New York
, United States
. Its southern terminus is at the northern end of the Brooklyn–Battery Tunnel in New York City, where it intersects with both Interstate 478 (I-478) and FDR Drive. The northern terminus of NY 9A is at U.S. Route 9 (US 9) in Peekskill
. It is predominantly an alternate route of US 9 between New York City and Peekskill; however, in New York City, it is a major route of its own as it runs along the West Side Highway
and Henry Hudson Parkway
. In Westchester County
, NY 9A follows the Briarcliff–Peekskill Parkway.
The origins of NY 9A date back to the 1920s when an alternate route of then-NY 6 from Yonkers
to Tarrytown
was designated as New York State Route 6A. NY 6 was redesignated as US 9 in 1927; however, NY 6A was not renumbered to NY 9A until the 1930 renumbering of state highways in New York. NY 9A was extended south into New York City in 1934 and north to Ossining in the late 1930s. In 1933, the Briarcliff–Peekskill Parkway opened as New York State Route 404. All of NY 404 was incorporated into an extended NY 9A in the late 1940s. NY 9A was extended northward to Peekskill in 1967 following the completion of the Croton Expressway
and southward to the Brooklyn–Battery Tunnel between 1985 and 1995.
Route 9A begins in lower Manhattan
at the north end of the Brooklyn-Battery Tunnel
(I-478) and heads north on the surface West Side Highway
and Henry Hudson Parkway
, crossing US 9 for the first time at the east end of the George Washington Bridge
. After crossing into the Bronx
via the Triborough Bridge and Tunnel Authority
-owned Henry Hudson Bridge
, Route 9A proceeds to leave the parkway at exit 23, joining US 9 on Broadway. The portions of NY 9A between 34th and 72nd Streets in Manhattan and from the Henry Hudson Parkway to the New York City line in the Bronx is maintained by the New York City Department of Transportation
. The concurrency between US 9 and NY 9A runs for 2.87 miles (4.62 km) within the city of Yonkers
. All of NY 9A within Yonkers is maintained by the city.
NY 9A separates from US 9 along Ashburton Avenue and heads north as Saw Mill River Road. It parallels the Saw Mill River Parkway
through Ardsley and Elmsford, to the west side of Hawthorne. The route meets the southbound New York State Thruway
(I-87
) at a partial interchange and later meets I-287
(the Cross Westchester Expressway) at a full interchange that provides a route to the northbound Thruway (I-87). NY 100
merges with NY 9A to form a 3.11 miles (5.01 km) concurrency carrying the names Saw Mill River Road and Briarcliff–Peekskill Parkway, parallel to the Taconic State Parkway
. NY 9A exits off this highway along the Briarcliff–Peekskill Parkway, while NY 100 continues straight as Saw Mill River Road. NY 9A merges to form a brief concurrency with US 9 as the Croton Expressway in Ossining
just south of the Croton River.
The second concurrency between US 9 and NY 9A runs for 0.65 mile (1 km), with Route 9A leaving the Croton Expressway at Croton Point Avenue in Croton-on-Hudson
. The highway heads north along Riverside Avenue and eventually joins old Albany Post Road
. After crossing US 9 once more in Cortlandt, Route 9A ends at the Welcher Avenue interchange
in southern Peekskill.
to Tarrytown
was assigned the NY 6A designation by 1926. This ran along the present alignment of NY 9A from Yonkers to north of Elmsford
, where it turned west on Old Saw Mill River Road, Neperan Road, County House Road and Bedford Road to end at NY 6 in Tarrytown. NY 6 was redesignated as US 9 when U.S. Highways were first posted in New York in 1927; however, NY 6A was not renumbered at this time. It was finally renumbered to NY 9A as part of the 1930 renumbering of state highways in New York.
New York City
initially did not mark numbered routes within its limits. In 1932, the New York Automobile Club drafted a plan establishing alignments for several routes through the city. In this plan, NY 9A went south through the Bronx
and into Manhattan
on Broadway while US 9 used Riverdale Avenue north of 230th Street. As a result, the two routes would have had a short concurrency
across Spuyten Duyvil Creek
. NY 9A would have split to the south on Tenth Avenue
at 218th Street in order to join the Harlem River Drive
via Nagle Avenue and Dyckman Street. From there it would head west on 155th Street
to Amsterdam Avenue, where it would head south to 79th Street
, heading west there to rejoin US 9 at Riverside Drive. US 9 would have continued south through lower Manhattan
to Staten Island
via the Staten Island Ferry
; however, it is unclear whether NY 9A would have continued south with US 9 to lower Manhattan.
The New York Automobile Club released another plan in 1933. This plan made no changes to NY 9A; however, US 9 was changed to use Broadway all the way through the Bronx and to travel to New Jersey
by way of the Holland Tunnel
. In the final plan implemented in mid-December 1934, no route was assigned to the Harlem River Drive – Amsterdam Avenue corridor. Instead, NY 9A used what had been planned as US 9, splitting at Broadway and Dyckman Street. NY 9A ran south along the west side of Manhattan on Riverside Drive
and the West Side Elevated Highway
(detouring around an unfinished section via 57th Street
, Eleventh Avenue
and 48th Street) to end at the entrance and exit plazas of the Holland Tunnel. US 9 was shifted northward to enter New Jersey via the George Washington Bridge
.
, Saw Mill River Road originally followed the Saw Mill River Parkway
corridor from Eastview to Hawthorne
. Ca. 1931, this section of Saw Mill River Road was designated as part of NY 142, a route that began at NY 100
on the Greenburgh
– Mount Pleasant
town line and followed Grasslands Road, NY 9A, and Saw Mill River Road north to Hawthorne, where it rejoined NY 100. The route went unchanged until it was removed ca. 1938. Its former routing was split into two routes—an extended NY 141
north of NY 9A and the new NY 100C
along Grasslands Road—by 1940. Ca. 1939, NY 9A was extended northward from Tarrytown to Archville, a small hamlet midway between Tarrytown and Ossining, by way of Sleepy Hollow Road.
Farther north, a new highway was built around Ossining
from Saw Mill River Road (NY 100) in Briarcliff Manor
to US 9 north of Ossining. The highway, known as the Briarcliff–Peekskill Parkway, was completed in 1933 and initially designated as NY 404. In the late 1940s, NY 9A was altered to continue north along a slightly realigned Saw Mill River Road from NY 100C near Elmsford
to the south end of the Briarcliff–Peekskill Parkway in Briarcliff Manor. At this point, NY 9A left Saw Mill River Road and followed the parkway to its end at US 9, supplanting NY 404. The realignment created a 3 miles (5 km) overlap between NY 9A and NY 100 from Hawthorne to Briarcliff Manor and resulted in the truncation of NY 141 back to its previous terminus in Hawthorne.
Construction on the Croton Expressway
, the only piece of the failed Hudson River Expressway project that was ever built, began in the mid-1960s. It became part of a realigned US 9 when it was completed in 1967. The former surface routing of US 9 along Albany Post Road
between Croton-on-Hudson
and Buchanan
became a northward extension of NY 9A, which reached the old alignment by way of an overlap with US 9 from the north end of the Briarcliff–Peekskill Parkway to Croton-on-Hudson.
replaced Riverside Drive
in the mid-1930s, NY 9A was moved onto it, eventually using the new parkway to where it crossed US 9 (Broadway) in the Bronx. Here, NY 9A exited the parkway and ran concurrent with US 9 to the split in Yonkers
. The Brooklyn–Battery Tunnel connecting Manhattan's Battery Park
to Brooklyn
was completed in 1950. By 1960, an extension of the West Side Elevated Highway south to the Manhattan tunnel portal became part of NY 27A
, which had ended in Brooklyn prior to the construction of the tunnel. On January 1, 1970, NY 27A was truncated on its western end to eastern Nassau County
while NY 27
was extended northward over NY 27A's former routing through the Battery Tunnel and the West Side Elevated Highway.
However, by 1973, NY 27 had been cut back to its interchange with the Gowanus Expressway in Brooklyn while I-478 was assigned to both the Battery Tunnel and all of the West Side Elevated Highway south of the Lincoln Tunnel
. NY 9A was cut back to the Lincoln Tunnel as a result. The extension of I-478 into Manhattan was eliminated following the collapse of part of the Elevated Highway in 1973, which led to the demolition of the highway south of 59th Street
. Demolition was completed in 1989. The surface streets that the Elevated Highway had run atop of—West Street, 11th Avenue and 12th Avenue—became an extension of NY 9A at some point between 1985 and 1995. In early 1996, construction began on a project to convert this section of NY 9A into the West Side Highway
, a six-lane urban boulevard with a parkway-style median and decorative lightposts. The first of the project's seven segments—between Clarkson and Horatio Streets in the Greenwich Village neighborhood—was completed in 1998. The last of the project's pieces was completed in August 2001.
