New Jersey Route 42 is a state highway in New Jersey linking the southern suburbs of Camden County, New Jersey and Gloucester County, New Jersey with urban centers in Burlington County, New Jersey and Essex County, New Jersey, providing connections to Atlantic City Expressway, Interstate 295, and Interstate 76. The corridor serves commuter, freight, and regional traffic between Philadelphia, Atlantic City, and Newark Liberty International Airport corridors while interfacing with historic routes such as U.S. Route 30 and U.S. Route 322.
Route description
The southern segment begins near Turnersville, New Jersey at an interchange with U.S. Route 322 and proceeds north as a limited-access highway paralleling the New Jersey Turnpike (I‑95) corridor, passing through sections adjacent to Pine Hill, New Jersey, Washington Township, Gloucester County, New Jersey, and Deptford Township, New Jersey while intersecting arterial roads including Route 55 (New Jersey) and County Route 551 (New Jersey). Northbound the route becomes a heavily engineered parkway-style expressway as it approaches the Atlantic City Expressway interchange and the major junction commonly known as the Black Horse Pike complex near Egg Harbor Township, New Jersey and Pleasantville, New Jersey, with connections to Route 168 (New Jersey) and County Route 536 (New Jersey). As the highway continues toward Camden, New Jersey and the Walt Whitman Bridge, it crosses rail corridors used by NJ Transit, Conrail, and Amtrak and passes near landmarks such as Haddonfield, New Jersey and the Adventure Aquarium, before terminating northbound near interchanges serving Interstate 76 and urban Newark, New Jersey approaches.
History
The roadway traces its origins to early 20th-century auto trails and state highway renumberings during the 1927 New Jersey state highway renumbering when planners aligned routes to support intercity travel between Philadelphia, Pennsylvania and Atlantic City, New Jersey. Mid-century improvements coincided with postwar projects such as the construction of the Atlantic City Expressway and expansion of the New Jersey Turnpike Authority network, influenced by federal programs like the Federal-Aid Highway Act of 1956 and coordination with regional agencies including the New Jersey Department of Transportation. The corridor saw major reconstruction during the late 20th century to handle suburbanization from Cherry Hill, New Jersey and Mount Laurel, New Jersey and accommodate growth tied to facilities like Philadelphia International Airport and the Port of Camden, with interchanges rebuilt to standards pioneered on Interstate 295 and Interstate 76 (Ohio–New Jersey) segments. Recent history includes interchange reconfigurations influenced by litigation, environmental review involving New Jersey Pinelands Commission, and multimodal planning with NJ Transit Bus Operations and regional freight planners.
Major intersections
Key junctions provide transfers to corridors operated by state and federal agencies, including the southern connection to U.S. Route 322, grade-separated interchanges with Route 55 (New Jersey), and the major complex linking Interstate 295 and Interstate 76 near Camden County, New Jersey; additional significant nodes include links to U.S. Route 30 (White Horse Pike), access to the Atlantic City Expressway leading toward Brigantine, New Jersey and Atlantic City, New Jersey, and northern terminations that interface with routes serving Newark International Airport and downtown Newark, New Jersey development districts. The corridor also intersects numerous county routes such as County Route 544 (New Jersey) and County Route 551 (New Jersey), and provides proximity to transit centers used by PATCO Speedline and River Line (NJ Transit) services.
Traffic and usage
The corridor carries a mix of commuter flows bound for Philadelphia, Pennsylvania and Newark, New Jersey, regional leisure travel toward Atlantic City, New Jersey casinos and beaches, and truck movements serving the Port of Paulsboro and Port of Philadelphia, producing peak congestion at interchange bottlenecks studied by the Metropolitan Planning Organization and the South Jersey Transportation Authority. Traffic counts reveal heavy weekday peak volumes influenced by employment centers in Cherry Hill, New Jersey, retail nodes around Deptford Mall, and air cargo movements at Newark Liberty International Airport, while seasonal surges align with events at Boardwalk Hall and tourist influxes to Ocean City, New Jersey and Wildwood, New Jersey. Safety analyses and crash data reviewed by the New Jersey Division of Highway Traffic Safety have identified high-collision segments prompting targeted countermeasures drawn from standards used on other busy corridors like Interstate 95 and U.S. Route 1.
Future developments and improvements
Planned projects include capacity upgrades, interchange reconstructions, and multimodal integration coordinated among the New Jersey Department of Transportation, Delaware Valley Regional Planning Commission, and local counties to improve freight access to the Port of Camden and to enhance commuter reliability to Philadelphia and Newark Liberty International Airport. Proposals evaluated in environmental studies reference design solutions implemented on corridors such as Interstate 295 and Route 73 (New Jersey), and consider transit enhancements linked to NJ Transit bus rapid transit concepts and park-and-ride expansions near Cherry Hill Mall. Funding and phasing depend on federal programs like the FAST Act and state capital plans administered by the New Jersey Economic Development Authority, with stakeholder engagement involving municipal governments in Gloucester County, New Jersey and Camden County, New Jersey.
