Interstate 280 (New Jersey)

Interstate 280 (New Jersey) is a 17.85-mile (28.73 km) auxiliary Interstate Highway located in northern New Jersey, United States. It provides a critical east-west link between the suburban communities of Morris County and the urban core of Newark, connecting major routes like Interstate 80 and the Garden State Parkway to the New Jersey Turnpike and the Port of Newark. Known informally as the "Essex Freeway," the highway traverses the Watchung Mountains and features the notable William A. Stickel Memorial Bridge crossing the Passaic River.

Route description

Beginning at a complex cloverleaf interchange with Interstate 80 in Parsippany-Troy Hills, Interstate 280 heads east through Livingston and West Orange. The highway cuts through the First Watchung Mountain via the 4,140-foot (1,260 m) Watching Reservation Cut, a significant engineering feature. It crosses the Passaic River on the William A. Stickel Memorial Bridge into Newark, where it terminates at an interchange with the New Jersey Turnpike (Interstate 95) near the Port Newark–Elizabeth Marine Terminal. The route is maintained by the New Jersey Department of Transportation and is six lanes for most of its length, serving as a major commuter corridor into Newark Liberty International Airport and the region's industrial centers.

History

The route of Interstate 280 was originally planned in the 1950s as part of the federal Interstate Highway System to alleviate traffic on local arteries like U.S. Route 46 and New Jersey Route 3. Construction began in 1958, with the first segment opening between Interstate 80 and Northfield Avenue in West Orange by 1965. The challenging section through the Watchung Mountains, requiring the deep Watching Reservation Cut, was completed in 1973. The final segment, including the William A. Stickel Memorial Bridge and the connection to the New Jersey Turnpike in Newark, opened to traffic in 1980, formally completing the highway. The bridge is named for William A. Stickel, a former Essex County engineer.

Exit list

The entire route is in New Jersey. All exits are unnumbered but follow a sequential mileage-based pattern from west to east. Key exits include the western terminus at Interstate 80 in Parsippany-Troy Hills, interchanges for Northfield Avenue and Eagle Rock Avenue in West Orange, and connections to New Jersey Route 508 (Mount Pleasant Avenue) and New Jersey Route 21 (McCarter Highway) in Newark. The eastern terminus provides direct access to the New Jersey Turnpike (Interstate 95), U.S. Route 1/9 Truck, and the Port Newark–Elizabeth Marine Terminal.

Major intersections

Major junctions include its western terminus at Interstate 80 in Parsippany-Troy Hills. East of there, it intersects the Garden State Parkway in East Orange, a crucial north-south artery. Within Newark, it has interchanges with New Jersey Route 21 (McCarter Highway) and Interstate 78 via a connector road. Its eastern terminus is a major multi-level interchange with the New Jersey Turnpike (Interstate 95), which also provides access to U.S. Route 1/9 Truck and the industrial facilities of Port Newark.

Auxiliary routes

Interstate 280 has no signed, designated auxiliary routes such as business loops or spur routes within New Jersey. However, it functions as a critical feeder to several other major highways, including Interstate 80, the Garden State Parkway, and the New Jersey Turnpike. The highway also provides indirect access to Interstate 78 via local connectors in Newark, and it is a primary conduit for traffic heading to Newark Liberty International Airport and the Port of Newark.
