Highway Dedication
Last updated
Last updated
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.
The earliest date on which you can request a one-off snapshot of a date in the past for data in this feature type is 29 September 2022.
The following sub-sections provide details about the attributes included with this feature type, their data types in the different output formats, and other important metadata about them.
Primary identifier for the feature. The OSID is a Globally Unique Identifier (GUID) and requires no centralised authority to ensure uniqueness. Note that the same OSID can occur in more than one feature type when a single feature is represented multiple times in the OS NGD.
