The current alignment of US 1 between Trenton and Newark was legislated as Route 26, Route S26 and Route 25, while the current route north from Jersey City to the George Washington Bridge became Route 1 and Route 6. In subsequent years, US 1 was moved onto its current routing between Trenton and the George Washington Bridge. The state highways running concurrent with US 1 were removed in 1953, around the same time the route was moved to the Trenton Freeway within Trenton and the old alignment became US 1 Alternate, part of which is now US 1 Business. By 1969, the Trenton Freeway was extended north to Whitehead Road in Lawrence Township, and that segment became Route 174. When the Trenton Freeway was completed north to US 1, the US 1 designation was shifted to the freeway, replacing Route 174.

, while the proposed Route 1 Extension became part of Route 25. In addition, Route 26 was designated along the former Trenton and New Brunswick Turnpike, while the current US 1 between Route 26 and US 130 became Route S26. North of current US 130, present-day US 1 to Newark also became a part of Route 25. The current US 1/9 between the Tonnele Circle and the George Washington Bridge meanwhile became parts of Route 1 and Route 6.State of New Jersey, Laws of 1927, Chapter 319. The Route 1 Extension, now designated Route 25, was complete in 1928 with the exception of the Pulaski Skyway. This road was considered the first superhighway in the United States. After the Pulaski Skyway opened in 1932, US 1 along with US 9 was rerouted to use it. By the 1930s, US 1 was routed to use Route 26, Route S26, and Route 25 between Trenton and Newark instead of Route 27. US 1 and US 9 were routed to use the George Washington Bridge over the Hudson River instead of the Holland Tunnel by the 1940s, following Route 1 and US 46/Route 6 between the Tonnele Circle and the George Washington Bridge.
The Trenton Freeway, a freeway through the city of Trenton, was first planned in 1950 to provide a bypass of Trenton and a connection to the new Trenton–Morrisville Toll Bridge. This freeway opened in December 1952 and became part of both US 1 and Route 26. In the

On January 1, 1953, the New Jersey Highway Department renumbered many of the State Routes. This renumbering was first proposed in 1951 in order to reduce confusion to motorists. A few rules were followed in deciding what to renumber:

that followed a month later, all the state highways running concurrent with US 1 were removed. In addition, US 1/9 Truck was designated as a bypass of the Pulaski Skyway (replacing Route 25T) and US 1/9 Business (now Route 139) was designated on the former Route 25 between the Tonnele Circle and the Holland Tunnel. Also, after the US 1 designation was moved to the Trenton Freeway, the former route through Trenton would become US 1 Alternate.

, New Jersey and Pennsylvania considered having I-95 cross over the Trenton–Morrisville Toll Bridge, and continue north on the existing US 1. The project was opposed due to inadequate highway standards (lack of shoulder ramps, and only two lanes in each direction). During this time, both states sought alternate routes for the proposed I-95. In 1960, New Jersey and Pennsylvania decided to designate the

recommended an extension of the Trenton Freeway from Whitehead Road to the traffic light at Bakers Basin Road and Franklin Corner Road. Once the extension was completed by the 1980s, the route number was then changed from Route 174 to US 1. The former alignment of US 1 along surface streets in Trenton was renumbered to US 1 Business, while the US 1 Alternate was dropped.
There had been plans to create a west–east spur of the New Jersey Turnpike called Route 92. It was to begin just north of the intersection of Ridge Road and U.S. Route 1 in South Brunswick and terminate at the mainline of the New Jersey Turnpike (I-95) at Exit 8A in Monroe Township. This proposal was cancelled on December 1, 2006, after the

decided to use funds to widen the mainline turnpike instead.
By the 1990s, many traffic lights along the segment of US 1 in West Windsor and Plainsboro were removed and replaced with exit ramps and overpasses. As a result, the traffic lights at Scudders Mill Road, Plainsboro Road, Alexander Road, and Meadow Road were eliminated. This was followed by building ramps to replace the traffic light at US 130 and US 1 located North Brunswick, completed in 2003. An environmental impact study has been conducted by Rutgers University’s Transportation Policy Institute and Center for Negotiation and Conflict Resolution to improve US 1 through the Penns Neck area. This project would eliminate the Penns Neck Circle where US 1 meets Washington Road (CR 571) and move US 1 onto a new freeway alignment in the area. In addition, CR 571 is planned to be realigned to intersect US 1 further to the north. In 2009, the segment of US 1 between I-287 in Edison and the Garden State Parkway in Woodbridge was rebuilt to include new ramps at several intersections and removed access to a couple of roads in a $53.9 million project that was intended to alleviate traffic and make this section safer.
