U.S. Route 1/9 is the concurrency of U.S. Route 1 and U.S. Route 9 from their junction in Woodbridge Township, New Jersey north to New York City, New York, United States. It is commonly known as "1 and 9", and many signs combine the two numbers into one shield, separated by a hyphen (1-9) or, less commonly, an ampersand (1&9).
The south end of the concurrency is the merge of US 1 and US 9 in Woodbridge. From there the route runs north as a surface road with some jughandles through Linden and Elizabeth. At Route 81, a freeway begins, carrying the route around the west side of Newark Liberty International Airport and onto the Newark Viaduct and Pulaski Skyway. The Pulaski Skyway continues for another 5.6 miles into Kearny and Jersey City in Hudson County. Trucks, prohibited from the Skyway, must use the parallel U.S. Route 1/9 Truck between the eastern end of Newark and Tonnele Circle in Jersey City.
At the east end of the Skyway, US 1 and 9 exit at Tonnelle Circle and merge with the truck route, and again become a surface road to the merge with U.S. Route 46 in Palisades Park. The three routes run together on an early freeway, merging into the George Washington Bridge approach (Interstate 95) and continuing over the bridge. US 46 ends at the state line in the middle of the bridge, but US 1 and US 9 cross the bridge into New York City. Shortly after entering Manhattan, U.S. Route 9 leaves Interstate 95 at Exit 1 onto West 178th Street and Broadway. U.S. Route 1 continues with Interstate 95 into the Bronx before exiting onto Webster Avenue (later to reach Boston Post Road).

Note: Due to inconsistencies in the NJDOT's straight line diagrams for US 1 and US 9, there is a margin of error of ±0.08 miles for mileposts for junctions along the US 1/9 concurrency between Woodbridge and Fort Lee. The margin of error is higher along the I-95 concurrency, thus mileposts for those junctions are given with less precision.
