Interstate 84 crosses the New York-Pennsylvania state line near the point where New York, Pennsylvania, and New Jersey meet, lying a mere 30 feet away from New Jersey upon crossing the Delaware River. Signs for the first interchange in New York, in fact, direct motorists to NJ 23. The junction connects to Orange County Highway 15 eastbound, and US 6 westbound. Local lore notes that 84 was originally to cross the tip of New Jersey, near High Point, but the state did not want to maintain so small a piece of highway so far away from the rest of its major highway network.
The New York section of the highway is missing Exit 9 and Exit 14. Exit 9 was supposed to be a clover-leaf intersection with an arterial highway (Alternate 9W) which was on the drawing boards from the late 1950s until well into the 1970s, and appeared as "proposed" on most commercial and government maps produced during that period. The highway was designed to detour traffic away from the downtown City of Newburgh. Eventually, protests by homeowner groups representing neighborhoods which would have been destroyed by the arterial highway, together with soaring property values, forced the state to abandon the proposed highway and instead concentrate its funding on widening Water Street along the riverfront as an arterial (first designated as "Marine Drive" and subsequently as "Rev. Dr. Martin Luther King, Jr., Boulevard"). Tax maps showed a cloverleaf shaped parcel of property just west of the Gidney Avenue overpass in the Town of Newburgh as owned by the State of New York until the late 1980s. The property was sold and is now the site of a medical office complex. To this day, there is no exit between Exit 8 and Exit 10, both in the Town of Newburgh.
Exit 14 was to be the north end of an expressway in the sequence. A new junction, exit 5A, opened November 20, 2007 with a direct freeway link to Stewart International Airport in the Town of Newburgh. Legislation is currently underway to have New York interstate junctions renumbered according to a mile-based system.
