U.S. Route 46 (US 46) is an east–west U.S. Highway, running for 75.34 mi, completely within the state of New Jersey. The west end is at an interchange with Interstate 80 (I-80) and Route 94 in Columbia, Warren County on the Delaware River. The east end is in the middle of the George Washington Bridge over the Hudson River in Fort Lee, Bergen County while the route is concurrent with I-95 and US 1/9. Throughout much of its length, US 46 is closely paralleled by I-80. US 46 is a major local and suburban route, with some sections built to or near freeway standards and many other sections arterials with jughandles. The route runs through several communities in the northern part of New Jersey, including Hackettstown, Netcong, Dover, Parsippany-Troy Hills, Wayne, Clifton, and Ridgefield Park. The road has been ceremonially named the United Spanish War Veterans Memorial Highway.

What is now US 46 was originally designated as three separate routes. Pre-1927 Route 5 was created in 1916 to follow the road from Delaware to Denville, pre-1927 Route 12 in 1917 to follow the route between Hackettstown and Paterson, and pre-1927 Route 10 in 1917 to run between Paterson and Edgewater. In 1927, Route 6 was legislated to run from Delaware east to the George Washington Bridge, replacing portions of Routes 5 and 12 and paralleling the former Route 10, which itself became Route 5 and Route 10N, the latter being shortly removed from the state highway system. In 1936, US 46 was designated to run from US 611 in Portland, Pennsylvania east to the George Washington Bridge. The route replaced Pennsylvania Route 987 to the Delaware Bridge over the Delaware, and from there followed Route 6 across New Jersey. In 1953, the Route 6 designation was removed from US 46 in New Jersey, and later that year, the route was realigned to end at US 611 in Columbia, New Jersey, replacing a part of Route 94. US 611 had been brought into New Jersey by two new bridges over the Delaware River, following a freeway between them that became a part of I-80. By 1969, US 611 was aligned back into Pennsylvania, and US 46’s western terminus remained as an interchange with I-80 and Route 94.
