9Road closure thresholds (including re-opening)#

Transport and Main Roads is committed to ensuring the safety of road users and the public and preventing damage to road infrastructure and, in most cases, adopts a conservative approach and treats all vehicles in the same manner when a decision is made to close a SCR. Accordingly, Queensland SCRs may be closed during wet weather and flooding events when:

• the depth of still water is 300 mm or more
• where water is flowing, Transport and Main Roads' District or Regional discretion can be used to close the SCR at a lower depth, depending on the speed of flow – the faster the flow of water, the lower the depth for closure, and/or
• SCRs may be closed at lower depths if upstream catchment rainfalls or flows are likely to cause water levels to rise to levels greater than 300 mm in the near future, and it is practical to do so.

Transport and Main Roads will re-open SCRs following inspection of the road and bridges by an authorised officer. Depending on the severity of the inundation, a full inspection may be required.
