Route description
Texas
The southern terminus is in Del Rio, Texas at an intersection with U.S. Route 90. It goes north of town co-signed with U.S. Route 277 for 20 miles (32 km). After splitting off, it enters Edwards County and Carta Valley. It meets SH 55 at the county seat, Rocksprings, before serving as the western terminus of SH 41. About 20 miles north of Rocksprings, the route meets with the headwaters of the South Llano River, which follows the route into Junction, Texas. It heads northeast into Kimble County, crossing the county line near Telegraph. At Junction, it meets both Interstate 10 and US 83. It then continues northeast through London, extreme southeastern Menard County, and Mason County.

Why this record matters
The phrase “u.S. Numbered Highway in Texas and Oklahoma in the 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.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 25, 2026. The linked authority identifier is Q4816863. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
