18.4.1 PROWs crossing the Highway at an angle.
Where a PRoW (green line) crosses another Highway at an angle, as in Figure 42, then the centrelines are drawn for both and they intersect in the centre of the other Highway, as shown.
Figure 42 - PRoW crossing another Highway at an angle
18.4.2 PROW is in the margins of a Highway.
- Where a PRoW is in the margins of a Highway of which it is part, for example in the verge, Footway or Cycle Way, then a separate centreline for the PRoW must not be created. In theory, such a PRoW should not be on the Definitive Map, but in practice there was not a legal order to remove it from the Definitive Map, or it was diverted into the margin of the Highway rather than deleted. The type 67 ASD Coordinate Record must reflect the true position of the PRoW. Figure 43 shows examples of this below.

18.4.3 PRoW running parallel to another Highway
- However, where a PRoW runs parallel to another Highway but is separated from it by an impassable or physical barrier (other than a safety barrier) then it must be recorded with a separate ESU. See Figure 44.

18.4.4 Dealing with obstructions
- Where a PRoW is physically obstructed, there may be an alternative route provided. Examples of this are:
- a house was built on a PRoW and another path provided around it, but the PRoW has not been diverted.
- a PRoW along a river bank or cliff was eroded and a different route must be identified by the landowner/Local Highway Authority.
Both routes need to be present in the NSG.
Note: The intention here is not to record a diversion that is a simple trespass, but the situation where a genuine alternative path was provided by the developer, but the public rights have not been altered to reflect this situation.
In Figure 45, the PRoW running directly from ESU C, D to B was obstructed by a house built upon it. A new path was provided via ESU E which is not a PRoW. Both Streets can have the same USRN but must have separate ESUs, alternatively if the descriptions are fundamentally different, a separate USRN can be used for ESU E.
The two routes are recorded as follows:
