Context paragraphs:
U.S. Route 1 in New Jersey: U.S. Route 1 (US 1) is a United States highway which parallels the East Coast of the United States, running from Key West, Florida in the south to Fort Kent, Maine at the Canadian border in the north.  Of the entire length of the route, 66.06 mi of it runs through New Jersey.  It enters the state from Pennsylvania on the Trenton–Morrisville Toll Bridge over the Delaware River in the state capital of Trenton, running through the city on the Trenton Freeway.  From here, US 1 continues northeast as a surface divided highway through suburban areas continuing into Middlesex County and passing through New Brunswick and Edison.  US 1 merges with US 9 in Woodbridge, and the two routes continue through northern New Jersey as US 1/9 to the George Washington Bridge over the Hudson River in Fort Lee.  At this point, the road continues into New York City along with I-95.

New Jersey Route 4: Route 4 is a state highway in Bergen County and Passaic County, New Jersey, United States.  The highway stretches 10.83 mi from Route 20 (McLean Boulevard) in Paterson east to an interchange with Interstate 95, U.S. Route 1/9, U.S. Route 46, and U.S. Route 9W at the George Washington Bridge approach in Fort Lee.  The route is a four- to six-lane 40 to divided highway its entire length, with the portion east of the Route 208 interchange in Fair Lawn a partial freeway consisting of interchanges and right-in/right-out intersections with a few businesses along the road, particularly in Paramus, where the route passes through a major shopping area consisting of numerous malls, Hackensack, Englewood, and Fort Lee.  West of Route 208, the route is a surface arterial that runs through commercial areas.  Route 4 intersects many important roads, including Route 208 in Fair Lawn and the Garden State Parkway and Route 17 in Paramus.  The highway is officially named the Mackay Highway, but is rarely referred to as such.

Cross Bronx Expressway: The Cross Bronx Expressway is a major freeway in the New York City borough of the Bronx, conceived by Robert Moses and built between 1948 and 1972.  It carries traffic on Interstate 95 (I-95) through the city, and serves as a portion of I-295 toward Long Island; a portion is also designated U.S. Route 1 (US 1).  The Cross Bronx begins at the Alexander Hamilton Bridge over the Harlem River, where the Trans-Manhattan Expressway continues west across Upper Manhattan to the George Washington Bridge.  While I-95 leaves at the Bruckner Interchange in Throgs Neck, following the Bruckner Expressway and New England Thruway to Connecticut, the Cross Bronx Expressway Extension continues east, carrying I-295 to the merge with the Throgs Neck Expressway near the Throgs Neck Bridge.  Though the road goes primarily northwest-to-southeast, the nominal directions of all route numbers west of the Bruckner Interchange are aligned with the northbound route number going southeast, and the southbound route number going northwest.

Interstate 95 in New Jersey: Interstate 95 (I-95) is a major Interstate Highway that traverses nearly the full extent of the East Coast of the United States, from Florida to Maine, with the exception of a small gap in New Jersey.

In Fort Lee, US 1/9 merges onto I-95 and crosses the Hudson River on the George Washington Bridge, where the two U.S. routes split a short distance into New York.  US 1/9 intersects several major roads, including I-278 in Linden, Route 81 in Elizabeth, I-78 and US 22 in Newark, Route 139 in Jersey City, Route 3 and Route 495 in North Bergen, and US 46 in Palisades Park.
