That should (theoretically at least) fix it. If an intersection doesn't have a
node, it's not actually an intersection. Then it's just two roads crossing one
another, presumably (assumed by the various routing software) on different
levels.
If you fixed the first intersection you had problems with
Ian, thank you for the update. While that solves that particular routing
task, I still get other routing errors in the same area (this one [0], for
example] I've updated the area by adding nodes at intersections (where
missing), hoping it fixes the problem.
I'll check this out again soon.
