Hi there, thanks for contributing to OSM project. Regarding the busway you added for Restwell St, it might not be straightforward in iD editor, but the original Restwell St already includes the contraflow bus lane information, so making your addition of the busway a redundant data, and to guideline, an roadway without median separation should be mapped as one way, not two. Also the way direction of the main Restwell St is upside down. Would you mind I correct this issue on your behalf?
Cheers,
Jimmy
