Hi, Thanks for your quick response. We have discussed the possibility of retaining paths and using the access=no, highway=no, disused:highway and abandoned:highway tags to reflect the fact that routes may still exist on the ground. However, such tags have minimal / low usage in OSM, are not rendered by routing engines, or are contentious. As these paths are on NT open access land, it was felt that access=no (which denotes the legal right) would not be reflective of our position. If there is a clear vote on which tags would be appropriate in this scenario, we are happy to take guidance from members of the OSM community. However, we felt that at this stage, removing the ways and monitoring the area for changes would be the best approach.
Permissive access is still provided in and around West Kennet Avenue, however rather than having one permissive path the archaeologists on site have decided to promote an area of open access to distribute foot traffic.
