State Highway 72 (SH‑72) is a 1.989-mile (3.201 km) state highway in Payette County, Idaho, United States, that connects U.S. Route 30 (US 30), south of new Plymouth, with Idaho State Highway 52 (SH‑52) in Hamilton Corner. SH‑72 is maintained by the Idaho Transportation Department.

## Route description

SH‑72 begins at a T intersection with US 30, about 1.4 miles (2.3 km) south of New Plymouth. (US 30 heads north toward New Plymouth, Fruitland, and Payette and south to run concurrent with Interstate 84 [I‑84] and on toward Caldwell and Boise.)

From its western terminus, SH‑72 heads east as a two-lane road through a rural farmland north of the Farmers Cooperative Canal. After an intersection with Blaine Road, the highway continues east toward the unincorporated community of Hamilton Corner.

In Hamilton Corner, SH‑72 reaches it eastern terminus at an intersection with SH‑52 and Sand Hollow Road. (Eastbound SH‑52 continues east toward Emmett and Horseshoe Bend. Westbound SH‑52 heads north toward Payette and Weiser. Sand Hollow Road [Old Highway 30] heads south toward I‑84, Sand Hollow, and Caldwell.)

## History

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.

## Future

SH‑ was closed through October 2017 for a bridge replacement and improvements to its junction with US 30 one mile south of New Plymouth. The roadway was scheduled to reopen in November 2017.

## Major intersections

The entire route is in Payette County.
