List of Interstate Highways in Utah
The Interstate Highways in Utah are maintained by the Utah Department of Transportation (UDOT). The Interstate Highway System is a nationwide system with only a small portion of these routes entering Utah. Originally, the State Road Commission of Utah, created on March 23, 1909 was responsible for maintenance, but these duties were rolled into the new UDOT in 1975. There are of Interstates within the state. The longest is Interstate 15 (I-15) at and the shortest is I-215 at . One unique former route is Interstate 415, which was never signed as such, and was only used as a temporary designation for the eastern portion of what is now the Interstate 215 belt loop around Salt Lake City.
New York State Route 22
New York State Route 22 (NY 22) is a north–south state highway that parallels the eastern border of the U.S. state of New York, from the outskirts of New York City to the hamlet of Mooers in Clinton County near the Canadian border. At , it is the state's longest north–south route and the third longest state route overall, after NY 5 and NY 17. Many of the state's major east–west roads intersect with, and often join, Route 22 just before crossing into the neighboring New England states, where U.S. Route 7 (US 7), which originally partially followed NY 22's alignment, similarly parallels the New York state line.
