Route 4 (New Jersey) is a state highway in northeastern New Jersey that runs east–west across Bergen County from Paterson to Fort Lee. The road connects suburban communities with regional arteries including Interstate 80, Garden State Parkway, and New Jersey Turnpike, and serves as a feeder for cross-Hudson travel to Manhattan via the George Washington Bridge. Route 4 is a mix of divided arterial boulevard, commercial corridor, and limited-access segments, reflecting layers of 20th-century planning and postwar development patterns in the New York metropolitan area.

Route description

Route 4 begins at an interchange with U.S. Route 46 in Paterson near the Passaic River and proceeds eastward through a patchwork of industrial zones, residential neighborhoods, and retail strips. Early segments abut landmarks such as Bergen County Courthouse, Pascack Valley, and the Passaic County Park System while intersecting state and county roads including CR 507 and CR 502. As it continues into Fort Lee the route transforms into a multilane boulevard flanked by shopping centers, office parks, and commuter parking serving NJ Transit bus routes and private coach services to Port Authority Bus Terminal.

The highway crosses major regional infrastructure: it intersects Interstate 80 near Elmwood Park and provides direct connections to the Garden State Parkway and New Jersey Turnpike via collector–distributor ramps. The eastern terminus sits at an interchange with U.S. Route 1/9 and Interstate 95 approaches to the George Washington Bridge, giving motorists access to Upper Manhattan and the Harlem River crossings. Route 4’s cross-section ranges from two-lane segments in older built environments to seven-lane commercial boulevards in suburban retail districts, with medians, signalized intersections, and grade-separated interchanges.

History

Route 4 was designated in the 1927 statewide renumbering, consolidating preexisting roadways that linked industrial towns and ferry terminals across northern New Jersey during the Automobile Age and the expansion of the Port of New York and New Jersey. Early 20th-century improvements paralleled developments such as the construction of the George Washington Bridge (opened 1931) and the subsequent shift of cross-Hudson traffic from ferries to road crossings. Postwar suburbanization and the rise of regional shopping centers in the 1950s and 1960s drove expansions, widening projects, and the addition of service roads near emerging complexes like Westfield Garden State Plaza and other mall developments.

Throughout the late 20th century, Route 4 saw incremental upgrades to interchange geometry and traffic control to accommodate rising volumes linked to the growth of Fort Lee as a commuter hub and the economic integration with New York City. Infrastructure programs overseen by the New Jersey Department of Transportation and county agencies reshaped segments to improve safety and freight access to industrial parks near Paterson and Hackensack River. Historical controversies have included property acquisition disputes, environmental review processes tied to wetlands adjacent to the Hackensack River Meadowlands, and community responses to widening proposals that would alter established commercial strips.

Major intersections

Route 4 connects with a constellation of significant roadways and nodes: - Western terminus: junction with U.S. Route 46 in Paterson near Passaic River access. - Intersection with CR 507 providing north–south linkages to Clifton and Saddle Brook. - Interchange with Interstate 80 offering regional east–west connectivity toward I-95 and Delaware Water Gap corridors. - Connections to Garden State Parkway via ramps serving north–south travel along the Jersey Shore and New Jersey Turnpike access to Newark Liberty International Airport. - Proximal links to U.S. Route 1/9 and Interstate 95 at the eastern end, facilitating access to the George Washington Bridge and Washington Heights.

These intersections function as multimodal transfer points with adjacent NJ Transit Bus facilities, park-and-ride lots, and private coach staging areas used by commuters to Manhattan.

Traffic and usage

Route 4 carries heavy commuter flows during weekday peak periods, with volumes influenced by inbound and outbound movements to Manhattan, employment centers in Bergen County, and retail activity at shopping corridors. Freight traffic serves distribution centers linked to the Port of New York and New Jersey, generating significant truck percentages on arterial segments. Traffic studies commissioned by the New Jersey Department of Transportation and metropolitan planning organizations have documented recurring congestion at signalized intersections near major malls and arterial bottlenecks where lane reductions occur.

Safety analyses cite collision clusters near commercial nodes and at merge areas leading to the Garden State Parkway ramps, prompting operational countermeasures including adaptive signal control, turn-lane extensions, and targeted enforcement by county police departments. Seasonal and event-driven demand, such as holiday shopping peaks and infrastructure disruptions on parallel routes like I-95, amplify short-term surges.

Future plans and improvements

Planned improvements for Route 4 focus on capacity management, multimodal integration, and safety upgrades coordinated by the New Jersey Department of Transportation and regional planning bodies like the North Jersey Transportation Planning Authority. Proposals include corridor-wide signal optimization, replacement or rehabilitation of aging structures, pedestrian and bicycle facility enhancements near transit hubs, and improved bus-rapid-transit amenities to enhance connections to Port Authority Bus Terminal services.

Environmental review efforts target stormwater management and wetland mitigation in segments adjacent to the Hackensack Meadowlands to comply with New Jersey Department of Environmental Protection standards. Long-range scenarios under study consider managed lanes, access management to reduce conflict points, and coordination with freight partners to shift peak truck movements. Municipalities along the route, including Fort Lee, Hackensack, and Paramus, continue to evaluate land-use strategies to balance economic development with corridor performance.
