 US 22 enters New Jersey from Easton , Pennsylvania on the Easton @-@ Phillipsburg Toll Bridge over the Delaware River . It heads into Phillipsburg , Warren County as a four @-@ lane undivided road maintained by the Delaware River Joint Toll Bridge Commission , eventually becoming a divided highway . East of the bridge , the westbound lanes pass through the bridge toll plaza , and the route has an eastbound exit and westbound entrance for Broad and Main Streets . From the previous exit , US 22 runs eastward as a brief limited @-@ access road maintained by the New Jersey Department of Transportation that ends in an interchange with Morris Street and Hillcrest Boulevard . At this point , the route becomes at @-@ grade Memorial Boulevard ; a commercial four to six @-@ lane divided thoroughfare with a wide median consisting of U @-@ turn ramps and jughandles . The median narrows as the road forms the border between Lopatcong Township to the north and Phillipsburg to the south . The route fully enters Lopatcong Township and comes to an interchange with Route 57 , with an eastbound exit and a westbound entrance . After passing the Route 57 junction , US 22 takes a southeasterly turn and passes over Norfolk Southern 's Washington Secondary before entering an agricultural area . The route forms the border between Pohatcong Township to the west and Greenwich Township to the east as it passes to the east of the Phillipsburg Mall . A short distance later , US 22 intersects CR 519 before heading back into a business district and meeting CR 638 . East of Alpha , the route intersects Route 122 , which is the final junction of the at @-@ grade section of US 22 .
