My OSM editing skills aren't that great (I've only done a few minor changes to date) so, could someone advise how best to edit a short section in Chester, where the north end of Dee Lane meets the A51, to allow Cycle.travel routing (& others) to use the short section of shared use path to the crossing to get across the A51. Other vehicles have to turn left onto the dual carriageway but the shared path allows cycles to turn right to access the crossing (technically by using the shared path on the left then turning right across Dee Lane, although I always just turn right off the road). Here is a Google StreetView link that may be clearer than my explanation. Currently routing takes you left & round a busy multilane roundabout to get toi the other side of the A51.

The request is linked - an option to override routing (similar to BikeHike's "follow road" on/off toggle) between 2 via points. Useful for where either the map doesn't allow something (either by error or the fact there isn't anything official to follow) & sends you on a convoluted route between 2 points when there is, in practice, a much simpler alternative - one example I can think of is access to a rail line route on the opposite side of a dual carriageway to a minor road that runs parallel to the dual carriageway. The simplest route is to simply cross the grass strip separating the dual carriageway from the minor road on foot & then cross the dual carriageway, but there is no formal path to do so. (Maybe I should put in a request with the Local Authority?) What is achievable in less than 100m routes as nearly 1km round 3 sides of a rectangle.
