New York State Thruway (oficiálně Governor Thomas E. Dewey Thruway) is a limited-access toll highway in the U.S. state of New York. Built in the 1950s by the State of New York in order to connect the major cities of New York, it is the longest toll road in the United States, with the 496.00 mile (798.23 km) mainline extending from the Pennsylvania/New York State border in the west to Albany in the east, and the New York City borderline to the south. In 1958 it was incorporated into the Interstate Highway System as portions of Interstate 87, Interstate 287, Interstate 95, Interstate 90, Interstate 84, and Interstate 190. It is operated by the New York State Thruway Authority (NYSTA).
Only three sections of the Thruway system are not part of the Interstate Highway System. One such section is the Garden State Parkway Connector, which branches from the Thruway mainline at exit 14A in Spring Valley to connect to the Garden State Parkway at the New Jersey state line near Montvale. Another section is located on the Thruway mainline within exit 24 in Albany, as the mainline is unnumbered for a brief distance between the point where Interstate 87 departs the roadway and Interstate 90 enters it. The third section, the longest such section on the Thruway, is a six-mile portion of the Berkshire Connector, which has no Interstate designation between exit 21A on the Mainline in Selkirk and exit B1 in Schodack, where the Berkshire Connector merges with I-90.
Of the 641.29 miles in the Thruway system, 632.31 miles (98.6%) carries at least one Interstate designation. Interstate 90, which comprises the bulk of the mainline and the Berkshire Connector, runs for 365.55 miles along the Thruway, including 17.70 miles as part of the Berkshire Connector and 347.85 miles on the mainline. Interstate 87 comprises the remaining 148.15 miles of the mainline, including an 18.86 mile long concurrency with Interstate 287 north of New York City. Interstate 84 covers another 71.46 miles, including the New York State Bridge Authority-maintained Newburgh-Beacon Bridge, while Interstate 287 spans 29.76 miles (including the 18.86 miles shared with I-87), Interstate 190 lasts for 21.24 miles and Interstate 95 covers 15.01 miles.
