St. George is bordered by its suburbs and other smaller cities; Washington and Hurricane to the east, Santa Clara and Ivins to the west-northwest, and the community of Bloomington which forms the southwestern part of the city.
Interstate 15 runs nearly through the center, severing many surface streets of the grid. The major roads, St. George Boulevard and Bluff Street are the main downtown arteries and interchanges, and also make up the Interstate 15 central business loop.
Much of the city's more exclusive, high-end neighborhoods were developed in the hills and mesas within the city to capture the scenic views. One such neighborhood is Stone Cliff, a high-end, master-planned, gated community of multimillion-dollar homes built on a hillside overlooking downtown and the valley from the southeast. Bloomington in the southwest area is a residential community centered around a golf country club, with most homes built in the mid-late 1980s. The Sun River area, south of Bloomington, is Utah's first and only active adult master-planned retirement community, offering golfing and resort-style amenities. Major new master-planned neighborhoods and communities such as Desert Color, in the South Block area of the city, are forecast to house over 30,000 new residents in the near future.
