US 1/9 Truck begins at an interchange with access to and from the southbound direction US 1/9, the Pulaski Skyway, in
the Ironbound section of the city of
Newark in
Essex County. 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
freeway, heading to the east. A short distance later, the road comes to an interchange with the
New Jersey Turnpike (
Interstate 95, or 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
expressway, 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. The truck route becomes a four-lane divided highway called the St. Paul's Viaduct that runs to the north of the Pulaski Skyway and passes through industrial sectors, crossing over the Northern Branch line and
CR 646. A short distance later, US 1/9 Truck comes to the
Tonnele Circle with US 1/9 and
Route 139, where it ends. The
East Coast Greenway runs along the north side of the highway. ==History==
