Request for information – FOI14498
Thank you for your email of 1 October 2014, requesting the following information in accordance with the Freedom of Information Act (FOIA) 2000:
1. On what date and for what reason was there a change from "white" roads being:
a) "Under 14 feet of metalling tarred (yellow) and untarred (white)" to simply "Other road, drive or track, fenced and unfenced".
b) "Minor roads in towns, drive, or track unmetalled" to simply "Other road, drive or track, fenced and unfenced".
I regret to inform you that Ordnance Survey is unable to help you with your enquiry as we do not hold this information. We do not hold this information because we do not keep current records on the history and rationale for the changes to the depiction of yellow-filled and uncoloured roads.
However, under our duty to provide advice and assistance as stipulated in Section 16 of the FOIA, we advise that we do hold a copy of a 1971 edition of the 1:25 000 second series, which includes the following relevant legend wording:
1. Under 14ft of metalling, tarred
2. Under 14ft of metalling, untarred
3. Minor road in towns, drive or track (unmetalled)
We enclose a copy of the relevant section of the legend which shows that type 1. is depicted as an unfilled road with long orange dashes; 2. is depicted as an unfilled road with shorter orange dashes; and 3. is depicted as an unfilled road. No roads from this period were depicted with a yellow infill.
The “1:25 000 second series specification” dated 1976 includes the following classifications:
4. Minor road generally less than 4m tarred
5. Minor roads untarred, minor road in towns, drive or track
This wording would have taken effect on revised editions produced from 1976 where we updated the roads. In these cases we would have amended the depiction and legend description to reflect the 1976 specification. Some sheets revised and reprinted after 1976 would have retained the earlier description.
We have enclosed a copy of the relevant page from the 1976 specification and you will again notice that no roads appear to have a yellow infill at this point.
The classifications in our current 1:25 000 scale Explorer specification appear below. Our records do not show when this took effect or the reasons why, or whether there were any intermediate alterations to these features since the 1976 specification.
Road generally less than 4m wide [top classification in diagram (yellow)]
Other road, drive or track, fenced or unfenced [bottom classification in diagram]
I hope you find the above information is helpful to you.
