The HAPMS network layer is produced and maintained as part of Highways England's pavement management system (HAPMS). The data is therefore designed for that purpose and no responsibility is accepted for the misuse or misinterpretation of this data. "Pavement" refers to the road surface, and not pedestrian access.
This data covers the majority of the Highways England road network - Trunk roads, motorways and other types of roads that Highways England is responsible for maintaining. It can be used to indicate the extent of Highways England's responsibility.
