Hello,

Designing more accurate road layout is a good idea.  But if you want to do such edits, could you please ensure not to break bus routes.

You should redistribute bus relations on the two one-way segments, depending on the direction buses are travelling.

What I see in the current revision is that buses running in both directions are directed to one of the one-way roads, and no bus route on the other.
