State Route 224 (SR-224) is a north–south state highway in the U.S. state of Utah. The route connects Interstate 80 and Kimball Junction in the north to Park City in the south. Ski resorts line the mostly four-lane highway, including Park City Resort and Deer Valley. The highway has changed paths many times since its formation in 1941, at one point connecting to Big Cottonwood Canyon and Salt Lake County. However, realignments brought the route to its present path by 1990.
