Hi both,

This does look like an incorrect addition to me. There are two tunnels (one cycle, one ped), and were correctly marked as starting south of the north portal and vice versa. The new added ways are not correct.

My bad. Fixing route breaks and validation problems. Hadn't looked carefully enough on OS StreetView and missed that Pikestone Lane does change mysteriously to Pikestol Lane. Agree this is probably wrong, but have undone change pending on-the-ground survey.
