Route description
State Highway 151 begins at a trumpet interchange with SH-51 east of Mannford. While elevated from this interchange, the highway crosses the BNSF Railway. SH-151, running north-northeast, then serves as the eastern boundary of Keystone State Park. It then runs across the top of Keystone Dam; on the west side of the dam lies Keystone Lake, while on the east side is the Arkansas River. After crossing the dam, the route ends at US-64/US-412 at another trumpet interchange, west of Sand Springs.
History

Why this record matters
The phrase “highway in Oklahoma” 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.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Dec 19, 2025. The linked authority identifier is Q2174409. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1964.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
