Highway Dedication
Highway dedication provides an indication of the type of Highway user who has access to that particular section of the Highway.
Against every section of geometry supplied by the local highway authority, there will be one of eight different types of Highway Dedication defined in the Highways Act 1980 and the Countryside and Rights of Way Act 2000 which determines the Highway user access.
There can only be one Highway Dedication type applied to the geometry at any given date or time.
It is likely that more than one Highway Dedication type applies to a section of Highway (i.e. a highway open to all vehicles will also have pedestrian way or footway access,) so the following is an order of priority where the highway dedications under each is inferred:
Motorway*
All Vehicles
Byway Open to All Traffic
Restricted Byway
Bridleway
Cycle Track* or Cycle Way
Pedestrian Way or Footpath
No Dedication or Dedication Unknown
*Motorways and Cycle Tracks (not Cycle Ways) impose restrictions on all other Highway users.
The Highway Dedication also identifies if the feature forms part of a National Cycle Route, Public Right of Way, Quiet Route, Physical Obstruction or Planning Order or Vehicular Traffic order exist.
The Highway Dedication value is only an inference of where a Public Right of Way exists and therefore is not the definitive record of Public Rights of Way, that is, the definitive map held by the relevant authority.
