According to bestitude, US 1 is a US Highway in the US state of New Jersey. The road is largely a multi-lane trunk road through the metropolitan suburbs of Philadelphia and New York, but parts of it are interstate highways, such as the Trenton Freeway and the Pulaski Skyway. The road runs for the entire 106 kilometers through urbanized areas.

Travel directions

De US 1 in Trenton.


US 1 in Pennsylvania crosses the Delaware River as a freeway at Trenton and then enters New Jersey as the Trenton Freeway. One then crosses State Route 29. Trenton is the capital of New Jersey and is a smaller subcenter within the Philadelphia metropolitan area. The highway runs in 2×2 lanes through the center of Trenton and the highway section ends after about 10 kilometers in the north of Trenton on the Brunswick Pike. It then follows one grade-separated intersection and then intersects with Interstate 295, the Trenton bypass, and the Philadelphia metropolitan eastern bypass.

US 1 is thereafter a wide urban arterial with expressway features. The road has 2×3 lanes and mainly grade-separated intersections. The road is a strip of shops and businesses. You then pass Princeton, which is roughly the division between the Philadelphia and New York metropolitan areas, although the built-up areas of both metropolitan areas simply merge into each other.

Central New Jersey

However, Princeton is still about 90 kilometers from New York City. US 1 is the main thoroughfare of this area and has only a few at-grade intersections. The road remains a substandard highway, with 2×3 lanes and many old grade separated intersections. This was built because of the discontinuation of the Somerset Freeway, which was originally to become Interstate 95 between Trenton and New Brunswick. Near New Brunswick, the first interchanges with the adjacent I-95/ New Jersey Turnpike follow. After crossing the Raritan River, the road also becomes a regular urban arterial againbecause through traffic is supposed to use the New Jersey Turnpike.

However, the road still has 6 lanes and is an important access road locally. At Edison, one crosses Interstate 287, the western ring road of the New York metropolitan area. Important intersections here are grade-separated. At Fords one crosses the important Garden State Parkway. From Woodbridge, US 9 merges with US 1. Both roads are then double-numbered for the rest of the route in New Jersey. Interstate 278 begins in Linden and leads to Staten Island and Brooklyn. One then passes through Elizabeth, a larger suburban town in New Jersey. You will then pass the Newark Airport. After this, US 1/9 is formed by the Pulaski Skyway. The Pulaski Skyway takes US 1 to Jersey City, then US 1 exits at Tonelle Avenue.

US 1 is then a four -lane urban arterial through the densely built suburbs of Union City, North Bergen and Hoboken. State Route 3 ends here and one crosses State Route 495. In Palisades Park, US 1 briefly becomes a freeway again, only to merge into Interstate 95 just before the George Washington Bridge, which then continues to Manhattan.


According to biotionary, US 1 was created in 1926. The route has not been changed in New Jersey since then, but it has been upgraded. In 1928, the world’s first cloverleaf cloverleaf opened in Woodbridge, between US 1 and NJ-35. This cloverleaf was reconstructed into a parclo in 2006-2007.


The section between the Pennsylvania border and White Head Road in northern Trenton opened as a highway in 1952 and 1953, first as NJ-26 and later NJ-174. When the highway opened, the road was seen as a role model of highway construction through urban areas. The US 1 runs right through the center of Trenton, the capital of New Jersey. In the mid-1950s, it was proposed that the then-new Interstate Highway Interstate 95to run across US 1. In the end, a somewhat more westerly route along Ewing, a suburb of Trenton, was chosen. In 1967 it was proposed to extend the freeway through Trenton a little north to relieve a busy street. This section opened in 1974, and was the last stretch of US 1 to be developed as a highway through Trenton.

In 1983, the New Jersey Department of Transportation was awarded $245 million for the cancellation of the Somerset Freeway, part of I-95. With the money, US 1 could be turned into a 2×3 lane semi-highway from Trenton to New Brunswick. Since then, there have also been plans to convert US 1 into a full highway. This has not yet been implemented, however, the current US 1 does have many grade-separated intersections, but also property connections between Trenton and New Brunswick.
