The highway heads east as a two-lane road through farmland north of the Farmers Cooperative Canal.

After an intersection with Blaine Road, the highway continues east toward the unincorporated community of Hamilton Corner.

[1][2] The entire length of SH‑72 was formerly designated as US 30, while US 30 south from the western terminus of SH‑72 to I‑84 was formerly Idaho State Highway 73.

Sand Hollow Road (Old Highway 30) south from Hamilton Corner was formerly designated as US 30 before US 30 was substantially re-routed in the area.

[3] The junction with US 30 was replaced with a T-intersection in late 2017 as part of a safety improvement project that also rebuilt a cuvlert.
