Route 120 is a state highway located in Bergen County, New Jersey, United States. It extends 2.65 mi (4.26 km) from an interchange with Route 3 in East Rutherford to another interchange with Route 17 in Carlstadt, where it continues to the west as County Route 120. Route 120 serves the Meadowlands Sports Complex - which consists of MetLife Stadium, Meadowlands Racetrack, and the Meadowlands Arena - and the American Dream shopping and entertainment complex. It heads north from Route 3 as a six-lane freeway through the sports complex to an interchange with the southern terminus of County Route 503. From here, Route 120 heads northwest along the northern edge of the sports complex as four-lane divided Paterson Plank Road, passing through industrial and commercial areas.

Route 3 is a state highway in the northeastern part of New Jersey. The route runs 10.84 miles (17.45 km) from U.S. Route 46 (US 46) in Clifton, Passaic County, to US 1/9 in North Bergen, Hudson County. The route intersects many major roads, including US 46, which takes travelers to Interstate 80 (I-80) west for commuting out of the city-area, the Garden State Parkway and Route 21 in Clifton, Route 17 and the Western Spur of the New Jersey Turnpike (I-95) in East Rutherford, the Eastern Spur of the New Jersey Turnpike in Secaucus, and Route 495 in North Bergen, for traffic going to the Lincoln Tunnel into New York City. Route 3 serves as the main artery to the Lincoln Tunnel from I-80, in conjunction with a portion of US 46 and Route 495. Portions of the route are not up to freeway standards; with driveways serving businesses and bus stops. Despite this, many construction projects have been underway over the years to alleviate this issue. Route 3 also provided access to Hoffmann La Roche's former American headquarters in Nutley, the Meadowlands Sports Complex and American Dream Meadowlands in East Rutherford. The road inspired a story in The New Yorker in 2004 by Ian Frazier due to its views of the Manhattan skyline. Route 3 was originally the Lincoln Tunnel Approach and ended at the state line in the Hudson River, though it was scaled back following the construction of I-495; which is now Route 495 due to also not meeting interstate highway standards.
