U.S. Highways in New Jersey provide a network of federally designated routes that supplement New Jersey Turnpike corridors and link metropolitan centers such as Newark, New Jersey, Jersey City, New Jersey, Camden, New Jersey, and Atlantic City, New Jersey. These highways intersect major arteries including Interstate 95, Interstate 78, Interstate 80, and the Garden State Parkway, and serve ports, airports, and rail hubs like Port Newark-Elizabeth Marine Terminal, Newark Liberty International Airport, and Penn Station (Newark).

Route list

The principal U.S. routes traversing the state include U.S. Route 1, U.S. Route 9, U.S. Route 22, U.S. Route 30, U.S. Route 40, U.S. Route 46, U.S. Route 130, and U.S. Route 206. Several of these run concurrently for portions of their alignments; notable concurrencies include the U.S. Route 1/9, U.S. Route 1/9 Truck, and the pairing of U.S. Route 22 with supplemental state routes such as New Jersey Route 173. Smaller or historically significant segments include spurs and alternate routings tied to U.S. Route 9W heritage and alignments near Trenton, New Jersey, Paterson, New Jersey, Camden County, New Jersey, Burlington County, New Jersey, and Cape May County, New Jersey.

History

The origins of numbered U.S. highways in New Jersey trace to the 1926 national plan coordinated by the American Association of State Highway Officials, later known as AASHTO, which assigned transcontinental and regional corridors such as U.S. Route 1 and U.S. Route 40. Early alignments followed preexisting turnpikes and plank roads including corridors once managed by the Camden and Amboy Railroad and Transportation Company and the New Jersey Turnpike Authority predecessor organizations. Twentieth-century developments—such as the construction of the Pulaski Skyway, the expansion of Route 4 and the later Interstate era epitomized by Interstate 95 in New Jersey—reshaped U.S. route functions, producing reroutings through suburbs like Elizabeth, New Jersey, industrial districts like Kearny, New Jersey, and shoreward approaches near Wildwood, New Jersey. Policy decisions during the Interstate Highway Act era prompted decommissioning and truncation of several routes, while metropolitan growth around Newark and Philadelphia generated capacity upgrades and bypasses, including projects implemented by the New Jersey Department of Transportation.

Route description and major junctions

U.S. route alignments in New Jersey combine urban arterial segments, limited-access stretches, and surface boulevards. U.S. Route 1 and U.S. Route 9 form an urban express concurrency through Hudson County, New Jersey and Union County, New Jersey, crossing the Pulaski Skyway and connecting to the Port Authority of New York and New Jersey facilities. U.S. Route 30 and U.S. Route 40 provide east–west connections to shore points; U.S. Route 40 intersects the Atlantic City Expressway and links to Atlantic City International Airport. U.S. Route 22 functions as a commuter corridor through Morris County, New Jersey and Somerset County, New Jersey, intersecting Interstate 287 and Interstate 78 near commercial nodes like Plainfield, New Jersey and Bridgewater Township, New Jersey. U.S. Route 46 parallels Interstate 80 across the Palisades approach, serving crossings at George Washington Bridge approaches and connecting to Route 17 near Ridgewood, New Jersey. Southern alignments such as U.S. Route 130 and U.S. Route 206 tie together industrial ports, military facilities such as Joint Base McGuire–Dix–Lakehurst environs, and state capitals—terminating or intersecting near Trenton and providing access to institutions like Rutgers University–New Brunswick and Princeton University via connector routes.

Major junctions include interchanges with Interstate 95, Interstate 78, Interstate 80, the New Jersey Turnpike, the Garden State Parkway, and cross-river connections to New York City and Philadelphia, Pennsylvania via the Lincoln Tunnel, Holland Tunnel, George Washington Bridge, and the Ben Franklin Bridge.

Maintenance and administration

Oversight of U.S. routes in New Jersey involves coordination between New Jersey Department of Transportation and federal standards promulgated by AASHTO. Routine maintenance, capital improvements, and roadway safety projects are managed by NJDOT regional offices with funding from state transportation budgets and federal programs administered through the Federal Highway Administration. Tolling and specialized infrastructure fall under authorities such as the New Jersey Turnpike Authority, the Port Authority of New York and New Jersey, and county agencies in Essex County, New Jersey and Burlington County, New Jersey. Preservation efforts incorporate collaborations with historic-preservation entities when alignment changes affect resources overseen by agencies like the National Park Service and regional planning organizations such as the North Jersey Transportation Planning Authority and the Delaware Valley Regional Planning Commission.

Former and decommissioned routes

Several U.S. routes have been realigned or decommissioned in New Jersey. Examples include historic routings of U.S. Route 9W approaches and earlier designations that were supplanted by interstates or state highways near Camden and Trenton. Decommissioned segments often survive as county routes or state-maintained corridors with legacy names linked to historic turnpikes such as the Burlington and Mount Holly Turnpike and alignments through municipalities including Morristown, New Jersey, Woodbury, New Jersey, and Haddonfield, New Jersey. Changes were driven by the Interstate Highway Act, urban renewal projects in Newark and Jersey City, and port modernization initiatives around Elizabeth, New Jersey and Bayonne, New Jersey.
