New York Route 9A originates along West Street by the entrance to the Hugh L. Carey (Brooklyn-Battery) Tunnel. West Street also extends north from the south end of Franklin D. Roosevelt (FDR) Drive, a limited access highway running along the east side of Manhattan Island. NY 9A runs along the west side, paralleling the Hudson River north. West Street transitions to 11th Avenue at W 14th Street and Chelsea. NY 9A along 11th Avenue shifts onto 12th Avenue at W 22nd Street. 12th Avenue extends NY 9A north to the Joe DiMaggio Highway at W 57th Street and the Upper West Side. Northward from Riverside Park, NY 9A follows Henry Hudson Parkway, a limited access roadway heading north to Washington Heights, Fort George and Inwood Hill Park at the northern end of Manhattan Island.
NY 9A spans Sputyen Duyvil Creek across the tolled Henry Hudson Bridge into the Sputyen Duyvil neighborhood of Bronx, New York. NY 9A measures 13.02 miles in New York County and 3.25 miles along Henry Hudson Parkway in Bronx County. NY 9A combines with U.S. 9 (Broadway) north from Henry Hudson Parkway through North Riverdale in the Bronx to Park Hill to Yonkers in Westchester County. NY 9A follows Saw Mill River Road north paralleling I-87 (New York Thruway) to Central Avenue through Elmsford. North from there, NA 9A runs between Saw Mill River and Sprain Brook Parkways to Hawthorne, and along Taconic State Parkway toward Ossining.
NY 9A bypasses the village of Ossining and reconnects with U.S. 9 at Crotonville. The two combine across the Croton River into Croton-On-Hudson, where NY 9A emerges alongside the Croton Expressway (U.S. 9) on Riverside Avenue. The two routes parallel each other through Crugers, Montrose and Buchanan. NY 9A ties back into U.S. 9 at its northern end at Welcher avenue and the Croton Expressway in the city of Peekskill. The state route totals 47.49 miles.
NY 9A previously ended at the Holland Tunnel, as NY 27A took over the remainder of the route south into Brooklyn. NY 9A was the continuation of U.S. 9 Business from New Jersey, which is why it ended at NY 27A; NY 27A followed the Belt Parkway east to John F. Kennedy International Airport (JFK).
There was once a two level toll booth for the Henry Hudson Bridge due to it being two levels across the Harlem River. The span now uses all electronic tolling (AET).
Historically NY 9A followed the Millers Westside Highway. The elevated roadway had a cobblestone road deck and left side exit ramps. Maintenance along the viaduct system was neglected, and the Westside Highway fell into disrepair and was subsequently closed and demolished. A proposal in 1971 called for building a new elevated expressway (Westway) north from Battery Park to the Lincoln Tunnel. Designated as Interstate 478, the Westway was never built.
