OS Open Roads
OS Open Roads is a high-level digital representation of Great Britain's road network. The links represent an approximate central alignment of the road carriageway and include roads classified by the National or Local Highway authority (for example, A roads) and unclassified roads, which together make up Great Britain’s road network.

OS Open Roads is a generalised product which is automatically simplified from Ordnance Survey large-scale data. Generalisation is the process of reducing the scale and complexity of the data whilst maintaining the important elements and characteristics of the features. The appropriate product scale is 1:25 000, with a recommended viewing scale range of 1:15 000 to 1:30 000.
