U.S. Route 1 in New Jersey is a portion of the United States highway which parallels the East Coast of the United States, running 2,390 miles (3,846 km) from Key West, Florida in the south, to Fort Kent, Maine at the Canadian border in the north, 66.1 miles of which are in New Jersey. In New Jersey, it runs from the state capital in Trenton, paralleling Interstate 95 and the New Jersey Turnpike while heading northeast to the George Washington Bridge in Fort Lee.

[edit] Route description

Upon crossing the Delaware River into New Jersey from Pennsylvania, the famous "Trenton Makes" Bridge is seen parallel to US 1 on the west side. US 1 begins as the 5.5-mile long Trenton Freeway from the Pennsylvania state line through the city of Trenton up to Lawrence Township in Mercer County. It then alternates between a 4-lane and 6-lane (mostly due to old bridges that weren't reconstructed when the highway was widened) principal arterial highway traveling through the Lawrence and West Windsor townships in Mercer County, the Plainsboro, South Brunswick, North Brunswick townships, the city of New Brunswick, and Edison and Woodbridge townships in Middlesex County, and the cities of Rahway, Linden, and Elizabeth in Union County. This segment is also known as the Herbert Highway and is 40.0 miles in length.

Though it was largely farmland in the early 1980s, by the 1990s the section of US 1 running through West Windsor and Plainsboro became one of the most traffic-congested corridors in the Northeast. A movement to eliminate many traffic lights and replace them with exit ramps and overpasses was put in place. As a result, the traffic lights at Scudders Mill Road, Plainsboro Road, Alexander Road, and Meadow Road were eliminated. While this effort hasn't eliminated the congestion, it has helped to alleviate it. This was followed by building ramps to replace the traffic light at US 130 and US 1 located in North Brunswick Township. There is currently a proposal to convert Route 1 into a depressed freeway through the Penns Neck area, and effectively eliminate the notorious Penns Neck Circle where Route 1 meets Washington Road (County Route 571). The project is not slated to begin yet, but it has been in planning for several years now and will likely get the green light in the next couple of years.^{[citation needed]}

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 Township, and terminate at the mainline of the New Jersey Turnpike (Interstate 95) at Exit 8A in Monroe Township.

Main article: U.S. Route 1/9

At their junction in Woodbridge Township, U.S. Route 1 begins a concurrency with U.S. Route 9. The two routes continue north, closely paralleling Interstate 95 and the New Jersey Turnpike, until they join I-95 in Fort Lee, crossing the George Washington Bridge into New York City.
