Trunk road network height information is provided in metres above sea level for the whole of the Scottish trunk road network. By selecting the layer options on the Map Layers and Key page, it is possible to view all parts of the trunk road network that are above a certain height. Selecting a visible road segment will provide details of the road and the altitude range within which it falls. It is intended that this page provides supporting information when planning journeys during periods of snowfall.

Altitude data is periodically gathered, on behalf of Transport Scotland, by a fleet of Road Assessment Vehicles (RAVs). These vehicles assist in providing road-related data, including alignment and altitude data, for the purposes of asset management.
