Interstate 84 (I-84) is a part of the Interstate Highway System that runs from Dunmore, Pennsylvania, to Sturbridge, Massachusetts, in the eastern United States. In New York, I-84 extends from the Pennsylvania state line at Port Jervis to the Connecticut state line east of Brewster. As it heads east–west across the mid Hudson Valley, it goes over two mountain ranges and crosses the Hudson River at the Newburgh–Beacon Bridge.
It is the only freeway to cross New York from west to east between New York City and the Capital District. As such it is the main vehicular route between southern New England and Pennsylvania and points west. It is maintained by the New York State Department of Transportation (NYSDOT), which resumed full control in 2010 after two decades in which routine maintenance was performed by the New York State Thruway Authority under yearly contract from DOT. The New York State Bridge Authority charges a toll for eastbound traffic crossing the Newburgh–Beacon Bridge.
Construction of the highway began later than other Interstates in New York as legal hurdles to the construction of the bridge had to be removed, and federal funding was more limited when it finally began in 1960. It was completed 12 years later, becoming a major commercial artery and mainstay of the Hudson Valley economy and offering travelers a view of some of the state's scenic areas in the Shawangunks and Hudson Highlands.
Route description I-84 passes through three counties. The entire stretch between the Delaware and Hudson, more than half the road's total length in New York alone, is in Orange County. East of the river the road begins in Dutchess County and then drops southward into Putnam County. As an Interstate Highway, all of I-84 in New York is included in the National Highway System, a network of roads important to the country's economy, defense, and mobility.
Two other highways parallel the Interstate for some length. U.S. Route 6 (US 6) follows it closely near the state lines, but takes a southerly course between those two areas. New York State Route 52 (NY 52) joins I-84 from Newburgh to Fishkill and remains parallel from there to Lake Carmel.
West of the Hudson River (Orange County)
I-84 enters New York near Port Jervis via a long bridge that crosses both the Delaware and Neversink rivers just above their confluence. This bridge is owned and maintained by the NYSDOT, including the portion in Pennsylvania. South of the road at the confluence is Tri-State Rock, where New Jersey, New York and Pennsylvania converge. For its first mile in New York, the Interstate is immediately north of the New Jersey state line in the city of Port Jervis. The first exit is signed for US 6 and New Jersey Route 23, which begins just south of the exit.
US 6 remains parallel to the north of the freeway as I-84 begins an immediate climb away from the state line up the Shawangunk Ridge, beginning an east-northeast slant in its direction that will continue for almost . The roadway crests at , its highest elevation in New York. Scenic overlooks on either side allow travelers to stop and take in the expansive view of Port Jervis, the lower Neversink valley and adjacent regions of Pennsylvania. On the descent, US 6 crosses under the Interstate again, reachable by a short drive south on Mountain Road at exit 4.
East of the Shawangunks it is to the next exit. The freeway winds through swamps from which the obelisk atop High Point, New Jersey's highest mountain, is visible. These give way to wooded areas eventually broken by fields in Wawayanda where Route 6 crosses over again to merge with NY 17M and recross at exit 15, the first of two that serve the city of Middletown. A mile and a half (2.4 km) further east along that roadway is the Middletown rest area, with restrooms and a state police substation. The other Middletown exit serves NY 17, the long freeway slowly being transformed into I-86, another mile farther to the east.
This junction is the western corner of Orange County's "golden triangle" of Interstates, so-called for its attractiveness to businesses for their distribution centers. Immediately afterward I-84 passes between the Galleria at Crystal Run, the county's largest mall, and the eponymous office park to the south. More farms begin to break up the landscape off the road. Westbound traffic is served by the Wallkill rest area four miles (6 km) east of Route 17. The tracks of Metro-North Railroad's Port Jervis Line runs just north of the highway for a short distance, and NY 211 also parallels for several miles past the hills of Highland Lakes State Park.
After crossing the Wallkill River and NY 416, I-84 climbs slightly to its first exit in almost , NY 208, serving nearby Walden and Maybrook. Heavy truck traffic at this exit reflects a nearby truck stop, Yellow Freight's (Now YRC) large presence in Maybrook, and rail-to-truck transload facility in the old Maybrook Freight train yard. In the area is a Staples warehouse north of the Interstate along NY 208 and numerous distribution centers (Home Depot, Do-it-Best and others) and truck terminals (including UPS, FedEx and 3 others), along an adjacent roadway on the south side. The highway continues, now almost due east, of this exit through more wooded area, forming the northern border of Stewart State Forest, for to the recently built exit with NY 747 intended to improve access to nearby Stewart International Airport.
A mile beyond, the road reaches the first of four exits serving Newburgh, the largest community along it in New York. It veers slightly to the north again after the interchange with NY 17K, which has been running parallel to the north since NY 208. Another truck stop is located off this exit, with a major FedEx and the U.S. Postal Service's Mid-Hudson General Mail Facility in the industrial park between the Interstate and the airport.
The freeway resumes its eastern heading again and descends a gentle slope to its junction with the New York State Thruway (I-87) and NY 300. Traffic was routed to the Thruway via a short section of 300 when the Interstate was built, but a major project to build a connector directly to the toll road was completed in December 2009, after being under construction for five years.
After passing through a rock cut, I-84 levels off and begins following the northern border of the city of Newburgh, where first NY 52 joins it, beginning the only concurrency with the Interstate in the state. A mile and a half (2.4 km) east, US 9W and NY 32 provide the last exit before the road crosses the Newburgh–Beacon Bridge, with views of Newburgh Bay and the Hudson Highlands to the south.
East of the Hudson River (Dutchess and Putnam counties)
The bridge also crosses Metro-North's Hudson Line tracks on the east side of the river. The NY 9D exit after the toll plaza is the first of two serving the city of Beacon, just to the south of the freeway. It then curves slightly to the north, passing Dutchess Stadium, home of the Hudson Valley Renegades, to the north and then the large open area between Downstate and Fishkill state prisons, where signs warn motorists not to stop. To the south a panoramic view from Beacon to Schunemunk mountains is available.
The road resumes its eastern heading and descends slightly to the next exit, where NY 52 leaves the freeway for the village of Fishkill. I-84 bends through the lowlands north of Sour Mountain, northern end of the Hudson Highlands, and crosses Fishkill Creek. Just north of the historic Van Wyck Homestead, and south of a large Old Navy regional distribution center, it intersects US 9, which becomes a divided highway from north of the exit to Poughkeepsie.
It begins to climb into the hills east of this exit, passing through some rock cuts in the to the Lime Kiln Road exit, which allows easy access to a nearby former IBM facility now known as Hudson Valley Research Park. From there it descends gently over , with Hosner Mountain looming to the east, to the sprawling interchange with the Taconic State Parkway. It ascends again afterwards, passing scenic overlooks on either side that allow views of the valley and the Catskills to the northwest. At the crest, near where the Appalachian Trail crosses over, signs indicate the road has once again reached 1,000 feet (305 m) in elevation.
I-84 begins to veer to the south at this point, and soon it descends through some rock cuts to cross into Putnam County just before the Ludingtonville Road exit, with NY 52 a short distance to the south. The road heads in a more south-southeast direction the next . The NY 311 exit offers the last connection to NY 52, a short distance to the south over Lake Carmel, and after crossing Metro-North's Harlem Line the interchange with NY 312 offers access to the large strip mall on a hill southeast of the exit and the Southeast train station.
After a quarter-mile-long (400 m) bridge over the Croton River, US 6, US 202 and NY 22 just north of Brewster, the Interstate returns to its eastern heading for the northern terminus of I-684, an exit that also provides access to the other three highways. For eastbound travelers this is the last exit in New York.
US 6 and US 202 closely parallel I-84 to the north, between the freeway and one of the upper basins of East Branch Reservoir, part of New York City's water supply system. The northern terminus of NY 121 lets eastbound traffic on and westbound traffic off. to the east, Signs appear for Saw Mill Road, exit 1 on Connecticut's stretch of I-84, and its ramps leave the highway just a hundred feet (30 m) before the state line.
History 1950s: Planning The route of what became I-84 through New York state began in the late 1940s, when the then-New York State Department of Public Works (now NYSDOT) was planning Gov. Thomas Dewey's proposed Thruway system. The plan was for the Thruway's main line to cross the river between Newburgh and Beacon, an area then in the middle of a gap in fixed river crossings. The remainder of the expressway would be toll-free.
Politicians in the Newburgh area had also been lobbying for a bridge over Newburgh Bay, as the ferry service in that section of the river was becoming financially nonviable. In 1951 they were able to authorize test boring in the riverbed to see if a bridge was feasible. It was, but their counterparts further up the river got legislation passed that prohibited any construction of the Newburgh Bay bridge until the Kingston–Rhinecliff Bridge was completed.
By the early 1950s the road plan had changed. The Thruway had been rerouted to cross the Hudson at the present site of the Tappan Zee Bridge. Dewey suggested that the future I-84 be built as a separate toll road instead. After the passage of the Federal Aid Highway Act of 1956, during the Averell Harriman administration, state officials changed it back to a free road in order to get federal funding for the project. It remained on paper as other New York Interstates got underway.
Assemblyman Lee Mailler of Cornwall, that body's majority leader, was able to get the bridge construction prohibition repealed in 1954. A bond issue the next year made the first money available for the construction of both the Kingston and Newburgh bridges. In 1959, it looked it would be delayed again when the federal funding formula was changed and less money was available, making a four-lane bridge too expensive to construct.
1960s–70s: Construction Construction began in 1960 after the new governor, Nelson Rockefeller, promised to expedite it during his campaign by building a single span, within the limits of what the state could afford without federal aid. The new plans called at first for a freeway connection for I-87 from Beacon to the Bronx and a concurrency across the river. After that project was cancelled after heavy local opposition. I-87 was routed to join I-84 at Brewster (where it would have followed the route of the current I-684).
