History
When UK roads were first classified in 1922, the A415 started at a junction with the A4 just west of Maidenhead in Berkshire. It ran through Henley-on-Thames and Benson to Shillingford where it joined the then A42. It left the A42 a mile west at Dorchester. In the 1930s the section from Maidenhead to Shillingford became part of the A423. It is now part of the A4130 and the A4074.
In the 1980s, when the Dorchester Bypass was opened, the start of the A415 was switched to the western end of the bypass, at Berinsfield.
Begin with the source’s own compact description: “A415 road” is road in England. The dossier treats that line as a proposition to test through A415, road and England, not as a finished interpretation.
Why this record matters
The phrase “road in England” 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 Feb 15, 2023. The linked authority identifier is Q4649271. Authority coordinates are 51.679, -1.408. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1762 and 1922.
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.
