Idaho State Highway 38
state highway in Oneida County, Idaho, United States
State Highway 38 (SH‑38) is a 23.438-mile (37.720 km) east–west state highway in Oneida County, Idaho, United States, that connects 2100 West and Old Highway 37 (northwest of Holbrook) with Interstate 15 (I‑15), just east of Malad City.
Route description
SH‑38 begins at an intersection with Old Highway 37 (also known as Rockland Highway and North Holbrook Road) and 2100 West (also known as Stone Highway) northwest of Holbrook. From the western terminus of SH‑38 the Old Highway 37, former routing of SH-37, continues northwest to the Power County line and the southern terminus of SH‑37. From its western terminus, SH‑38 heads east through a rural area between sections of the Curlew National Grassland. It takes a more crooked route east of Holbrook, intersecting Arbon Valley Road. From there, the SH‑38 enters mountainous terrain, passing Holbrook Summit at an elevation of 6,104 feet (1,860 m). After passing through the mountains, SH‑38 enters a rural area and passes through the unincorporated community of Pleasantview. SH‑38 then turns northeast toward Malad City, passing south of the Malad City Airport. After entering Malad City, the route turns eastward, passing through a mixed residential and business district. SH‑38 leaves the Malad City limits before reaching its eastern terminus with I‑15 at a diamond interchange.

Why this record matters
The phrase “state highway in Oneida County, Idaho, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 26, 2025. The linked authority identifier is Q842804. Authority coordinates are 42.176, -112.442. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
