Interstate 287 in the context of "Tappan Zee Bridge (2017–present)"

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.

U.S. Route 22 (US 22) is a United States Numbered Highway stretching from Cincinnati, Ohio, in the west to Newark, New Jersey, in the east. In New Jersey, the route runs for 60.53 miles (97.41 km) from the Easton–Phillipsburg Toll Bridge over the Delaware River in Phillipsburg, Warren County, to Interstate 78 (I-78), US 1/9, and Route 21 at the Newark Airport Interchange in Newark, Essex County. The road first heads through the Phillipsburg–Alpha area as an arterial road before running concurrent with I-78 through mountainous and agricultural sections of western New Jersey between Alpha and east of Clinton in Hunterdon County. For the remainder of the route, US 22 runs to the south of I-78 through mostly suburban areas as a four- to six-lane arterial road, passing through Hunterdon, Somerset, Union, and Essex counties. Along this portion, it intersects US 202 and US 206 in Somerville, I-287 in Bridgewater Township, and the Garden State Parkway in Union.

What became US 22 in 1926 was first designated as Route 9, a route running from Phillipsburg to Elizabeth, in 1916. In 1927, Route 9 west of Elizabeth became Route 28 while the portion within Elizabeth became Route 27-28 Link. By 1941, US 22 was moved to its current alignment in the Phillipsburg area, following Route 24 and Route 24-28 Link; Route 28 in Phillipsburg became US 22 Alternate (US 22 Alt.; now Route 122). Also, US 22 was moved off Route 28 east of Bridgewater Township to follow Route 28-29 Link and Route 29 to Newark. In 1953, the long concurrencies with the state highways were removed. In the 1960s, I-78 was constructed close to the US 22 corridor throughout New Jersey. US 22 was moved onto the new Interstate between Alpha and Clinton in 1969 with most of the old route becoming Route 173.

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).
