General descriptionThe Motorway and Trunk Roads are the main transport arteries in Wales and they carry the highest volume of traffic per vehicle kilometre. The Welsh Government is the highway authority for the motorway and the trunk road network, whilst all other public highways are the responsibility of the local authority it’s within. These statistics present information about the length and condition of roads in Wales and are based upon financial year.
Statistical qualityMotorway: Roads identified as M on road signs and which are reserved for use by certain types of traffic only. The A48(M) is included in this group. The data are provided by the Welsh Government's Network Management Division.
A: trunk roads: A trunk roads comprise the national network of strategic routes which cater for the through movement of long distance traffic for which the Welsh Government is the highway authority. The network comprises some of the all-purpose roads (A roads), which are open for use by all classes of traffic, and special roads such as motorways (which are separately identified in the tables). For all other public roads the local authorities are the highway authorities.
