Skyway, in the Ironbound section of the city of Newark in Essex County. The truck route is meant to bypass the portion of US 1/9 along the Pulaski Skyway, which trucks are restricted from. It merges onto Raymond Boulevard, which continues west from the US 1/9 and US 1/9 Truck interchange into Downtown Newark. The truck restriction on US 1/9 is for the "safety and welfare of the public" according to NJDOT, not a specific bridge defect. At this point, the truck route becomes a four-lane divided highway, heading to the east. A short distance later, the road comes to an interchange with the New Jersey Turnpike (Interstate 95 [I-95]) and Doremus Avenue before crossing over the Passaic River on a vertical lift bridge. Here, the route enters Kearny in Hudson County and continues east into industrial areas as the Lincoln Highway. The road has a right-in/right-out in both directions that provides access to Jacobus Avenue before it comes to an interchange with County Route 659 (CR 659). From here, US 1/9 Truck passes under a Conrail Shared Assets Operations (CSAO) railroad line and becomes a six-lane divided highway, coming to an at-grade intersection with Hackensack Avenue. Past this intersection, the road crosses the Hackensack River on a vertical lift bridge and enters Jersey City. Upon entering Jersey City, the road becomes Communipaw Avenue and intersects the northern terminus of Route 440 near the Hudson Mall. At this intersection, Communipaw Avenue continues to the east toward Communipaw and US 1/9 Truck turns to the north, becoming an unnamed four-lane undivided road and bisecting Lincoln Park before coming to an intersection with CR 605. Here, the road becomes a four-lane divided highway again, passing some urban business areas before running between wetlands to the west and Holy Name Cemetery to the east. The route heads into more commercial areas again before passing urban residences, coming to an intersection that provides access to the Pulaski Skyway. Here, US 1/9 Truck turns east on Broadway, running through a business district. A short distance later, it turns north onto an unnamed road with CR 642 continuing east on Broadway. The route passes under PATH's Newark–World Trade Center line and CSAO's Northern Branch line before crossing under the Pulaski Skyway. Immediately after, US 1/9 Truck intersects the eastern terminus of Route 7 and turns to the east, with CR 645 continuing north at this intersection.
