United Kingdom Trunk Roads

These details scraped from the Highways Agency Website, and Transport Scotland's Website.

Please note that this is a formal, and little-used, UK government classification. It does not necessarily mean that these are the only roads which should be tagged with highway=trunk. Many UK OSM users follow the practice that all green-signed A routes (ie primary routes) are tagged highway=trunk, while black-and-white-signed A-roads (ie non-primary routes) are tagged highway=primary.

There is a map on the Transport Scotland website showing the current officially designated trunk roads for Scotland. This shows the trunk road network following a reorganisation which resulted in many of the previous trunk roads being downgraded. In many cases the downgraded roads are still signed with the old green signs.
