Interstate 287 in the context of "U.S. Route 22 in New Jersey"

Tarrytown is a village in the town of Greenburgh in Westchester County, New York, United States, in the New York metropolitan area. It is located on the eastern bank of the Hudson River, approximately 25 miles (40 km) north of Midtown Manhattan in New York City, and is served by a stop on the Metro-North Hudson Line. To the north of Tarrytown is the village of Sleepy Hollow (formerly "North Tarrytown"), to the south the village of Irvington and to the east unincorporated parts of Greenburgh. The Tappan Zee Bridge crosses the Hudson at Tarrytown, carrying the New York State Thruway (Interstates 87 and 287) to South Nyack, Rockland County and points in Upstate New York. The population was 11,860 at the 2020 census.

The New York State Thruway (officially the Governor Thomas E. Dewey Thruway and colloquially "the Thruway") is a system of controlled-access toll roads spanning 569.83 miles (917.05 km) within the U.S. state of New York. It is operated by the New York State Thruway Authority (NYSTA), a New York State public-benefit corporation. The 496.00-mile (798.23 km) mainline is a freeway that extends from the New York City line at Yonkers to the Pennsylvania state line at Ripley by way of I-87 and I-90 through Albany, Syracuse, and Buffalo. According to the International Bridge, Tunnel and Turnpike Association, the Thruway is the fifth-busiest toll road in the United States. The toll road is also a major route for long distance travelers linking the cities of Toronto, Buffalo, and Montreal with Boston and New York City.

A tolled highway connecting the major cities of New York was first proposed in 1949. The first section of the Thruway, between Lowell, New York (south of Rome) and Rochester, opened on June 24, 1954. The remainder of the mainline was opened in 1955, and many of its spurs connecting to highways in other states and the Canadian province of Ontario were built in the 1950s. In 1957, much of the Thruway system was included as portions of Interstate 87 (I-87), I-90, and I-95. Other segments became part of I-190 and I-287 shortly afterward. Today, the system comprises six highways: the New York–Ripley mainline, the Berkshire Connector, the Garden State Parkway Connector, the New England Thruway (I-95), the Niagara Thruway (I-190), and the Cross Westchester Expressway (I-287). The portion of I-84 in New York was maintained by the Thruway Authority from 1991 to 2010, but it was never part of the Thruway system and is currently maintained by the New York State Department of Transportation (NYSDOT).

The Tappan Zee Bridge (English pronunciation: /ˌtæpən ˈziː/ ), officially named Governor Mario M. Cuomo Bridge after the former New York governor, is a twin cable-stayed bridge spanning the Tappan Zee section of the Hudson River between Tarrytown and Nyack in the U.S. state of New York. It was built to replace the original Tappan Zee Bridge, which opened in 1955 and was located just to the south. The bridge's north span carries the northbound and westbound automobile traffic of the New York State Thruway, Interstate 87 (I-87) and I-287; it also carries a shared use path for bicycles and pedestrians. The south span carries southbound and eastbound automobile traffic.

Although not as old as other bridges such as the George Washington, the original Tappan Zee was built in the midst of a material shortage during the Korean War and was thus only designed to last for approximately half a century. The process to replace the bridge kicked off in 2012, with construction on the new spans beginning by contractor Tappan Zee Constructors in 2013. The Left Coast Lifter, one of the largest cranes in the world, was instrumental in the bridge's construction. The north span officially opened to westbound traffic on August 26, 2017, and eastbound traffic temporarily began using the north span on October 6, 2017. Contractors then began demolishing the old bridge. An opening ceremony for the south span was held on September 7, 2018, and traffic started using the new span three days later.
