The heavy rainfall during the floods caused significant damage along Captain Cook Bicentennial Drive, cutting off safe access to the top of the North Brother mountain lookout.

Port Macquarie-Hastings Council has been working in partnership with National Parks and Wildlife Service (NPWS) to plan repairs. Work should be completed in around four weeks.

Director of Infrastructure Dan Bylsma said the damage was largely caused by a cracked stormwater pipe underneath the road that was overloaded during the intense weather event.

"As this road borders National Parks land, we have been working closely with National Parks and Wildlife Service to plan for repairs," Mr Bylsma said.

"Our intent is to start works next week to reinstate access, we are looking at a timeline of roughly four weeks for these repairs."

Mr Bylsma said the region's road and bridge network sustained significant damages as a result of the March 2021 floods, with more than 300 locations identified as requiring structural repairs.

"Our initial response has been directed towards restoring access to communities and removing detours," he said.

"As key routes such as Comboyne Road and the Stoney Creek Bridge are reinstated, we are turning our attention to projects such as this, that are not affecting access to residential properties but do provide an important recreational facility for our community."
