Interesting one! Looking at the OSM data, it was mapped as “one way road [i.e. the eastbound half of the dual carriageway] with a cycle track”, but there was no indication that the cycle track could be used against the one-way flow.

I’ve now corrected the data on OSM: it’ll be reflected in the cycle.travel routing when I next update it in a few weeks’ time. Thanks for spotting.

Thanks. I think this kind of mismatch is quite common on Sustrans routes: I wonder why OpenStreetmap itself displays the ncn OK.

NB Is it hard to have an option to route from start to dest using NCN routes x,y,z?
