ROUTE

Southern Parkway, Phase 1
The first phase of the Dixie Beltway is the called the Southern Parkway. It runs from Sun River to the Atkinville interchange (I-15, Milepost 2). Then 4 miles down to the Utah-Arizona border and over to a River Road interchange.

Southern Parkway, Phase 2
Phase 2 will continue from the River Road interchange 4 miles out to the new replacement airport, where there will be an Airport Road interchange.

Southern Parkway, Phase 3
Phase 3 will run from the Airport Road interchange 3 miles up to a Warner Valley Road interchange.

Southern Parkway, Phase 4
Phase 4 will run from the Warner Valley Road interchange 8 miles over to a 4300 West interchange.

Southern Parkway, Phase 5
Phase 5 will run from the 4300 West interchange 8 miles around the south end of Sand Hollow Reservoir and up to State Route 9 at about 2800 West in Hurricane.

Western Corridor
The Western Corridor is the western segment of the Dixie Beltway from I-15 at the new Atkinville Interchange to Old Highway 91 between Ivins and Santa Clara. This is targeted for some time beyond the year 2024.
