Trunk road network

What is the trunk road network?

The trunk road and motorway network includes major A roads and motorways that connect Scotland's major cities, towns, airports and ports enabling the movement of people, goods and services.

The trunk road and motorway network is 3,507km, makes up 6% of Scotland's roads and carries over one third of all traffic in Scotland and 60% of heavy goods vehicles. It does not include local roads, which are managed by local authorities.
