Oh, that's a little exasperating! The road was incorrect in OSM - someone erroneously dragged it. It's now been fixed in OSM but unfortunately the cycle.travel map update happened at the time when the road was wrong.

It'll be fixed next time I take a fresh feed from OSM: updating the map and routing data takes several days in all (on a very loud server which sits behind my desk and makes it hard to think!) so it's not something that is practical to run continuously. Usually I'd expect to update the data every month or so but I'll look into whether I can just run an update for the UK sooner.

Thanks. I wasn't sure what was going on as the OSM data was OK when I'd spotted it.

Maybe you ran the update at just the wrong moment!
