Besides the one I already put up in the comments on the changes set (https://www.abc.net.au/news/2023-05-08/demolition-of-asbestos-ghost-town-wittenoom-begins/102316358), there is also this information published by the Government of Western Australia here (https://www.wa.gov.au/government/document-collections/state-land-contaminated-sites#wittenoom).

Do you have any source for the ENTIRE road(s) still being open, and not just that part of the road(s) that is/are OUTSIDE the contaminated area?
