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 71.46 miles (115.00 km) 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.
