Zone 1 - Segments traversing primarily rural, agricultural areas with low population density. The two primary segments in this zone are located south of Provo, extending to Arizona along I-15 and to Colorado along I-70. This zone also includes shorter segments of I-80 and I-84 bounded by the Wyoming and Nevada State lines respectively. Approximately 90% of this zone borders agricultural land.
Zone 2 - Segments traversing primarily sub-rural areas with low population density. Segments in this zone are located in the north-central, north-eastern and north-western regions of the State. Land usage is primarily agricultural (approximately 75%), with light pockets of industrial, commercial, and residential land usage.
Zone 3 - Segments traversing sub-rural/suburban land around the State's metropolitan areas with medium population density. Segments in this zone are located outside the Salt Lake City metropolitan area. Land usage is mixed; while agriculture still makes up the largest proportion of land usage, about one-third of the land is residential, and slightly less than one-third is commercial and industrial.
Zone 4 - Segments traversing suburban/urban areas with medium/high population density. Segments in this zone run on a north-south route on I-15 through the Salt Lake City metropolitan area. Land usage in this zone is mixed, with the greatest proportion categorized as industrial, followed by residential, then commercial, and small pockets of agricultural usage.
Zone 5 - Segments traversing the densely populated urban areas. Segments in this zone are located in and around Salt Lake City. Nearly half is categorized as residential, and the rest is split between industrial and commercial usage, with very small pockets of agricultural usage.
