State and US Roads in New York City

Trans-Manhattan Expressway, Cross Bronx Expressway, Webster Avenue, Fordham Road, Boston (Post) Road

LOCATION: New York-New Jersey border (George Washington Bridge) to Bronx-Westchster border
NOTES: The alignment of US 1 through New York City has been in place since 1977. Between 1926 and 1931, US 1 went through Manhattan via the Holland Tunnel and the 1931-1972 alignment for NY 1A. Prior to 1977, US 1 left I-95 at Broadway (US 9). After three blocks north on Broadway, US 1 turned east onto the Washington (Heights) Bridge. Once in the Bronx, US 1 turned north onto University Avenue, then east onto Fordham Road.

(Houston Street, 1st Avenue / 2nd Avenue, Willis Avenue / Third Avenue Bridges, Bruckner Boulevard, Hutchinson River Parkway)

Manhattan to Westchester
NOTES: In Manhattan, NY 1A was the original US 1 alignment  (1926-1931). When it was originally assigned in 1931, NY 1A in the Bronx followed Southern Boulevard, Pelham Parkway and Shore Road into Westchester County. When it was completed in 1941, the Hutchinson River Parkway "extension" in the Bronx was given the NY 1X designation. By 1946, the Bronx alignment of NY 1A was changed to Bruckner Boulevard and the Hutchinson River Parkway. The NY 1A designation was removed in 1972.

(Major Deegan Expressway, Sedgwick Avenue)

Bronx (Triborough Bridge approach to Van Cortlandt Park)
NOTES: NY 1B was the designation for the section of the Major Deegan Expressway (between the Triborough Bridge and Grand Concourse) that was completed in 1936. The NY 1B designation was removed in 1956, when the Major Deegan Expressway was completed through the rest of the Bronx. Upon completion, the expressway was designated I-87.

(Hutchinson River Parkway)

Bronx (at Bruckner Boulevard) to Westchester
NOTES: NY 1X was a short-lived designation along the Hutchinson River Parkway. Assigned in 1941 upon completion of the parkway, the NY 1X designation was replaced with that of NY 1A in 1946.

(Original NY 22 alignment)

Manhattan (at Houston Street) to Westchester
NOTES: Between 1926 and 1930, US 7 was routed along the 1930-1972 alignment for NY 22 through Manhattan and the Bronx. The southern terminus of US 7 was shifted to Norwalk, Connecticut in 1930.

Trans-Manhattan Expressway, Broadway

LOCATION: New York-New Jersey border (George Washington Bridge) to Bronx-Westchster border
NOTES: The alignment of US 9 through Manhattan and the Bronx has been mostly unchanged since 1934. (Prior to 1931, US 9 exited Broadway at 125th Street, and went over a trans-Hudson ferry to Edgewater, New Jersey. From 1931 to 1934, US 9 traveled down Broadway to South Ferry, where it went over the Staten Island Ferry to Hylan Boulevard in Staten Island.)

West Side Highway, Henry Hudson Parkway, Broadway

LOCATION: Manhattan (at West Street and Brooklyn-Battery Tunnel approach) to Bronx-Westchester border
NOTES: Originally, the NY 9A designation along the West Side Highway began at the Holland Tunnel. (The NY 27A designation began south of the tunnel.) The NY 9A designation leaves the Henry Hudson Parkway at EXIT 23, just before the Bronx-Westchester border.


New York-New Jersey border (125th Street Ferry) to Bronx-Westchster border
NOTES: During the late 1920's, this was the designation for US 9 east of the Hudson River from New York City north to Albany.

(Bailey Avenue)

Bronx (at NY 1B-Sedgwick Avenue to Van Cortlandt Park)
NOTES: The NY 9X designation along Bailey Avenue disappeared by the late 1940's.

Provost Avenue

LOCATION: Bronx (at US 1-Boston Post Road) to Bronx-Westchester border
NOTES: NY 22 through New York City was part of the original (pre-1930) US 7 alignment. From 1930 until 1956, this route was multiplexed with NY 100 through Manhattan and the Bronx. NY 22 began in Lower Manhattan at Houston Street (NY 1A), and went north along Fourth and Park Avenues. (It even wrapped around Grand Central Station.) NY 22 turned west at 110th Street in Harlem, and after three blocks, turned north again at Lenox Avenue. The route turned east at 145th Street and crossed over the Harlem River before continuing north along Grand Concourse in the Bronx. At the end of Grand Concourse, NY 22 continued north along Jerome Avenue to East 233rd Street, where it continued east. Finally, NY 22 turned north at Provost Avenue onto its current route. In 1972, NY 22 in the Bronx was truncated to its current 0.5-mile-long length. For one of New York State's most venerable routes, NY 22 ends in the Bronx virtually unnoticed (i.e., without reassurance shields).

212th Street / Hollis Court Boulevard, Hempstead Avenue

LOCATION: Queens Village (at intersection of I-295 and NY 25) to Queens-Nassau border
NOTES: The alignment for NY 24 through Queens changed course more than once. In 1940, NY 24 began at the Queensboro (59th Street) Bridge and went east along Queens Boulevard (mostly multiplexed with NY 25) to Hillside Avenue. NY 24 went east along Hillside Avenue, then south along 212th Place (eastbound) / 212th Street (westbound) and east along Hempstead Avenue. By 1950, NY 24 went from the Queens-Midtown Tunnel along the Queens-Midtown Expressway (later the LIE), the Laurel Hill Boulevard Viaduct section of the Brooklyn-Queens Connecting Highway (later I-278 / Brooklyn-Queens Expressway) to Queens Boulevard, then continued along the original route to Nassau. At that time, NY 24 shields began to appear along 39th and 40th Streets in Manhattan, as well as at the approaches to the Queens-Midtown Tunnel. In 1958, NY 24 was routed along the entire length of the Long Island Expressway, which was multiplexed with I-495 to the Clearview Expressway. (Hillside Avenue, 212th Place / 212th Street and Hempstead Avenue became NY 24A.) In 1962, when the LIE east of the Clearview was redesignated NY 495, NY 24 returned to its 1950 alignment, and the NY 24A signs were removed. In 1972, NY 24 was moved two blocks west and shortened to its present alignment, with its western terminus at the intersection of Hillside Avenue (NY 25) and the Clearview Expressway (I-295). However, after community protest from Queens Village residents concerning the routing of NY 24 through residential streets, NY 24 signs were removed from 212th Street (westbound) and Hollis Court Boulevard (eastbound) in the mid-1970's. This segment of NY 24 continues to exist today as an unmarked segement.

(Hillside Avenue, Hollis Court Boulevard, Hempstead Avenue)

Jamaica to Queens-Nassau border
NOTES: This was the short-lived designation for the original alignment of NY 24. Between 1958 and 1962, the Long Island Expressway had the NY 24 designation. Once the LIE east of the Clearview was redesignated NY 495 in 1962, this segment became NY 24 once again, and the NY 24A  signs were removed. Between 1962 and 1972, the short segment of Hillside Avenue between the Clearview Expressway (then I-78) and NY 25 (Broaddock Avenue) was designated NY 24A, albeit as an unmarked route.

Queensboro Bridge, Queens Boulevard, Hillside Avenue, Braddock Avenue, Jericho Turnpike

LOCATION: Manhattan (at approach to Queensboro Bridge) to Queens-Nassau border
NOTES: The original alignment for NY 25 through Queens went along Queens Boulevard east to Kew Gardens, then turned east along Union Turnpike. The NY 25 designation then turned south at Springfield Boulevard to Braddock Avenue, where it continued on its present alignment. The NY 25 alignment shifted south along Hillside Avenue (which had been NY 24) in 1972.

21st Street, Jackson Avenue, Northern Boulevard

LOCATION: Long Island City (at I-495, EXIT 14) to Queens-Nassau border
NOTES: In the 1960's, the Astoria Expressway (early designation for I-678) was planned along the Northern Boulevard-Astoria Boulevard corridor. It was not until 1972 that the NY 25A designation was extended from Queensboro Plaza to the Queens-Midtown Tunnel (via Jackson Avenue and 21st Street).

Hillside Avenue

LOCATION: Queens Village (at NY 25) to Queens-Nassau border

(Union Turnpike)

Bayside (at Springfield Boulevard) to Queens-Nassau border
NOTES: Prior to 1972, NY 25 was the designation for Union Turnpike from Kew Gardens to Bayside. East of Bayside, NY 25C continued east along Union Turnpike into Nassau County. When NY 25 was realigned to Hillside Avenue in 1972, the NY 25C designation was removed from Union Turnpike in Queens. 

(Horace Harding Boulevard)

Elmhurst (at NY 25-Queens Boulevard) to Queens-Nassau border)
NOTES: In 1939 and 1940, NY 25D was ceremonially named "World's Fair Boulevard." The "Horace Harding" alignment was ultimately used for the construction of the Long Island Expressway through Queens, and even today, the service roads there bear the name "Horace Harding Expressway."  NY 25D continued east into Nassau County as Nassau Boulevard, whose alignment was also used for the LIE. The NY 25D designation along the LIE was replaced by I-495 and NY 24 in 1958.

Prospect Expressway, Caton Avenue (via East 5th Street / Church Avenue), Linden Boulevard, Conduit Avenue, Sunrise Highway

LOCATION: Brooklyn (at I-278) to Queens-Nassau border
NOTES: Originally, NY 27 began in Lower Manhattan at Canal Street near the Holland Tunnel approach. It crossed the Manhattan Bridge into Brooklyn, where it went along Flatbush Avenue before continuing onto Atlantic Avenue, Washington Avenue, Eastern Parkway, Rockaway Parkway and Linden Bouelvard. The current Brooklyn alignment dates back to 1972. In contrast, the alignment through Queens has not changed. (The Atlantic Expressway, the limited-access replacement for Sunrise Highway through Long Island, was to begin in Rosedale, Queens, near the Belt Parkway and Nassau Expressway.)

(West Side Highway, Gowanus Parkway, Belt Parkway)

Manhattan (at Holland Tunnel approach) to Rosedale
NOTES: Once upon a time, NY 27A was a continuous route from Manhattan to Suffolk County. Before the Gowanus and Belt Parkways were completed, NY 27A began at Delancey Street in Lower Manhattan. The route went across the Williamsburg Bridge into Brooklyn, where it continued along Broadway and Fulton Street. In Queens, NY 27A went along Rockaway, Baisley and Merrick Boulevards. NY 27A continued east into Nassau County as Merrick Road. The route of  NY 27A was changed in 1950, when it was routed along the West Side Highway in Lower Manhattan, then along the Brooklyn-Battery Tunnel. NY 27A continued along the Gowanus and Belt Parkways into Queens, and ended at Sunrise Highway in Rosedale. The NY 27A designation was removed from the Gowanus Parkway (Expressway) by 1958, and by 1972, the NY 27A designation was removed from the Belt Parkway. However, a few NY 27A signs (along with the old wooden lightposts on which they were posted) remained standing on the Belt Parkway into the mid-1980's.

(Fourth Avenue / Park Avenue, Grand Concourse, Jerome Avenue)

Bronx (East 149th Street to Bronx-Westcheter border)
NOTES: In Manhattan and the Bronx, NY 100 was multiplexed for most of its length with NY 22. At East 233rd Street in the Bronx, NY 22 went east, while NY 100 continued north along Jerome Avenue into Yonkers. The section of NY 100 north of East 233rd Street would become the alignment for the Major Deegan Expressway and the New York State Thruway (I-87). When these highways were completed in 1956, the NY 100 designation through the Bronx was eliminated.

(Bruckner Boulevard, Baychester Avenue, Nereid Avenue)

Bronx (Hutchinson River Parkway-Cross Bronx Expressway interchange to Bronx-Westchester border)
NOTES: The NY 164 designated was given in 1939 to direct motorists from Westchester and the Bronx to the Bronx-Whitestone Bridge and the 1939-1940 World's Fair. The designation was eliminated with the completion of the eastern segment of the Bruckner Expressway (I-95) in 1961.

(Forest Avenue, Victory Boulevard, Bay Ridge Avenue, 4th Avenue, Shore Road Drive)

Staten Island (at Goethals Bridge) to Brooklyn (at Belt Parkway, EXIT 1)
NOTES: First appearing in 1949, the NY 439 was the continuation of NJ 439 across the Goethals Bridge. The entire length of Forest Avenue, and the easternmost 0.75 mile of Victory Boulevard carried signs for the route. (NY 439 was also to be the designation for the never-built North Shore Expressway along the Forest Avenue-Richmond Terrace corridor on the north shore of Staten Island.) Before the Verrazano-Narrows Bridge was completed in 1964, NY 439 continued into Brooklyn via the St.George-Bay Ridge ferry. Once in Brooklyn, NY 439 continued along Bay Ridge Avenue, 4th Street and Shore Road Drive to the Belt Parkway. The NY 439 designation was removed in Brooklyn by 1964, and in Staten Island by 1972. However, signs for NY 439 (including some of the old "cutout" design) remained standing until the late 1970's. Even today, older destination signs direct motorists from the southbound Dr. Martin Luther King, Jr. Expressway (NY 440) to "NY 439 -- Forest Avenue."

(Victory Boulevard)

Staten Island (Arthur Kill to NY 439-Forest Avenue)
NOTES: The NY 439A designation, which was posted on the remainder of Victory Boulevard, was eliminated in 1972.

Outerbridge Crossing, West Shore Expressway, Staten Island Expressway, Dr. Martin L. King, Jr. (Willowbrook) Expressway

LOCATION: Staten Island (Outerbridge Crossing to Bayonne Bridge)
NOTES: The NY 440 designation, like its NY 439 counterpart, first appeared in 1949 as a continuation of NJ 440. Originally, NY 440 went from the Outerbridge Crossing to Drumgoole Boulevard (which later became the alignment for the Richmond Parkway). At the end of Drumgoole Boulevard, NY 440 continued north along Richmond Avenue to the southern approach of the Bayonne Bridge. The completion of the West Shore Expressway in 1976 necessitated a new alignment for NY 440: north from the Outerbridge Crossing to the West Shore Expressway, east along the Staten Island Expressway (multiplexed with I-278), then north along the Dr. Martin L. King, Jr. Expressway to the Bayonne Bridge.

(Long Island Expressway)

Bayside (at I-295 / Clearview Expressway) to Queens-Nassau border
NOTES: The NY 495 designation replaced the NY 24 designation along the LIE east of the Clearview in 1963. This segment was redesignated I-495 in 1983.

Nassau Expressway

LOCATION: South Ozone Park (at Belt Parkway, EXIT 19) to Springfield Gardens (at Rockaway and Farmers Boulevards)
NOTES: The NY 878 designation first appeared in 1990, when the Interstate designation (I-78 from 1971 to 1989, I-878 from 1989 to 1990) was dropped. NY 878 is in two separate segments: a limited-access segment in Queens, and an at-grade segment in Nassau County. These segments are separated by the unsigned Rockaway Boulevard in Queens, and Rockaway Turnpike in Nassau County.
