The Bergen County section was part of the Bergen-Passaic Expressway, a road planned in the 1940s but not completed until the 1960s to alleviate congestion on US 1/9/46 and NJ 4 as approaches to the George Washington Bridge. Specifically, the Bergen-Passaic Expressway was designed to pull Paterson-bound traffic off NJ 4. When the road was added to the Interstate highway system, it became part of a greater conduit from the west; however, the last sections of I-80 west of Paterson were not completed until the 1970s.
Contrary to popular belief, I-80 does not go to New York, even though New York is given as a control city on eastbound signs throughout New Jersey and even near Youngstown, Ohio (but not, curiously, in Pennsylvania). Prior to the completion of I-95 in the Ridgefield Park area, the entire Bergen-Passaic Expressway was signed I-80; today, the road's eastern terminus is at the New Jersey Turnpike in Teaneck.
Only the 8.1-mile portion of the freeway in Bergen County is included here; the mile markers are from the highway's New Jersey origin at the Delaware River.
