South I-15 Corridor

The communities south of Idaho Falls along the I-15 corridor into northern Bingham County. Shelley (pop. ~5,200) is the largest community, a small city known for its annual Idaho Spud Day festival and its location at the edge of Idaho's famous potato-growing country. Firth is a smaller farming community just south of Shelley. While technically outside the MSA boundary, both towns are economically tied to Idaho Falls and commonly considered part of its commuter shed.
