The route begins in the Heber Valley - part of the Wasatch Back - at the intersection of Main Street and Center Street in the city of Midway and heads west along Main Street through from the center of town through shops and homes. After two blocks, the route turns north on 200 West Street and turns west again two blocks later onto 200 North street. After travelling west for through residential communities, the route turns again to the north along Homestead Drive, passing by the Homestead Resort, Homestead caldera and the Utah Golf Resort and leaving the city limits. Just outside Midway, Homestead Drive curves to the west at the entrance of Wasatch Mountain State Park. At this point, State Route 222 turns right onto Warm Springs Road to continue north, taking a jog to the east to skirt the east edge of the golf course on the state park. As it passes the golf course, the route merges with Pine Canyon Road and resumes its northward direction, passing the Wasatch Mountain State Park Campground as it begins to climb out of the valley and follow Pine Creek into the foothills of the eastern Wasatch Range. Just after passing the campgrounds, the route ends at the pavement change coincident with a gate. The remainder of the road, which is closed in the winter and not designated as part of the state route, continues north to meet with other roads that provide access to Park City in Summit County via SR-224 to the north over Empire Pass, and Brighton in Salt Lake County via SR-190 to the west via Guardsman Pass.
History
The southern portion of SR-222 was initially designated as Utah State Route 224 in 1941, running from SR-113 in Midway north to Schneitter's Hot Pots, now the Homestead Resort. In 1953, the route was extended north to the boundary of Wasatch Mountain State Park. This extent of SR-224 is what now comprises SR-222. Incidentally, SR-224 was extended again in 1963 farther north over Empire Pass to Park City, and yet again in 1969 north all the way to I-80 at Kimball Junction. In 1990, the state and Wasatch County executed a trade, wherein SR-32 around the south side of the Jordanelle Reservoir was restored to the state highway system, and portions of SR-190, SR-220, and SR-224 became county roads. In particular, SR-224 was removed from the state highway system between the Pine Creek Campground and the Wasatch/Summit county line. The unconnected southern portion between SR-113 and the campground, however, remained part of SR-224 until 2004, when it was redesignated as SR-222 to eliminate confusion.
