From what I remember, there used to be an A lane only for the stop and then 2 lanes for everyone. Then they extended them all the way with yellow ones. The yellows are supposed to be temporary - but it has been a year now, so it's unclear how "temporary" they really are. They do look pretty much permanent now. I have no info about what is planned here, it might be in some documents somewhere. But it's a lot of work to go finding those...

I personally have no idea if there is some easily accessible public transport lane list (and that we have the license to use). It's probably buried in individual work orders and projects and not like a map or anything.
