Route 3 is a state highway in the northeastern part of New Jersey. The route runs 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 (also I-95) 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 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.
Route 3 was originally established in 1927 to run from the New York state line on the west shore of Greenwood Lake to Secaucus. In 1929, the western terminus was cut back to Paterson when the alignment west of there was planned to become part of Route S4B. Route 3 originally followed present-day Route 20 through Paterson and ran along local streets to East Rutherford, where it followed present-day Route 120 and Paterson Plank Road to Secaucus. It was extended east to the Lincoln Tunnel in 1939. The section of Route 3 between US 46 in Clifton and East Rutherford was completed in the 1940s as Route S3 as well as the Secaucus Bypass, which was designated a bypass of Route 3. Route 3 was moved to the Route S3 freeway and the Secaucus Bypass in 1953 and was truncated to US 1/9 in North Bergen in 1959 when the Lincoln Tunnel approach was designated as I-495. The Route 3 freeway has seen many improvements over the years, such as widening and interchange reconstructions. It underwent a major reconstruction, completed in 2016, to modern highway standards with bridge replacements, including a new Passaic River bridge between Clifton and Route 17 in Rutherford.
Route description

Route 3 heads to the southeast, from an interchange with US 46 and Valley Road (County Route 621 [CR 621]) as a six-lane arterial road with a jersey barrier. It is not up to freeway standards, as it contains a few businesses with right-in/right-out access. The route intersects Grove Street (CR 623) and Broad Street (CR 509), then the Garden State Parkway, where it passes south of the Allwood Road Park & Ride, a park and ride lot serving NJ Transit buses. All interchange movements are present between Route 3 and the Garden State Parkway, except from the southbound Garden State Parkway to westbound Route 3 and from eastbound Route 3 to the northbound Garden State Parkway. Just after crossing the river, the route intersects Riverside Avenue (CR 507). The freeway continues through a residential area and comes to an exit that provides access to southbound Route 17. Past this interchange, Route 3 is closely paralleled by Route 17 to the south until Route 3 intersects Route 17 again, which continues to the north of Route 3. In 1929, the route west of Paterson was designated to become part of Route S4B, a spur of Route 4, and Route 3 was modified to end at Route S4B north of Paterson. Route S4B was never built west of Paterson while the portion that was built became Route 208 in 1953.
Following the 1929 amendments, Route 3 ran from Paterson along today's Route 20, through Clifton, Passaic, Wallington, Carlstadt, and East Rutherford along local streets, and finally down Paterson Plank Road (part of which is today's Route 120) to Secaucus. Before 1938, a bypass around the original Paterson Plank Road bridge over the Hackensack River was built, parts of which were later incorporated into today's Route 120. As of this point, plans were in place to bypass the Plank Road to the north, going north of Wood Ridge and Wallington and replacing River Road up to Route 6, where it would rejoin the old alignment. In 1939, Route 3 was extended east along present-day Route 495 to the Lincoln Tunnel into Manhattan.
