Hi
Do you have a source for Jacob's Well roundabout on Princes Way and Hall Ings south of city park still being open?
Mapillary or Kartaview imagery would be ideal.

Hi
Do you have any images of the freeway bridge?

Please use a street level imagery recorder like Mapillary or Kartaview if you're through the area again.
That way we have a series of images with associated gps trace allowing accurate mapping.

Is there a source for this?

Is there a good source I can use to change it back?
