A local engineer has raised concerns about the level of preparation on Illawarra roads for a major rain event such as the heavy falls experienced this week.
In a letter to Transport for NSW Regional Director South Sam Knight, seen by The Mercury, the engineer questions why preparation for landslides has not been made on roads known to be at risk.
"I'm in both rage and disbelief that - with the amount of investment on our roads on the south coast - you have not prioritised making the area surrounding the existing highways and major roads resilient to landslides?"
A Transport for NSW spokesperson said the agency inspects all roads including slopes to monitor their condition and identify areas of concern to keep roads safe.
"Our focus now is addressing the unfolding impacts from a far-reaching and significant weather event to ensure the safety of motorists and our crews on scene," the spokesperson said.
"Transport for NSW teams will continue working to keep roads open where possible, or close and repair as required. With the high levels of rainfall experienced, some areas will be inundated with water and these roads will be closed to ensure the safety of the public. When water levels subside, inspections and any necessary work will be done to re-open roads as quickly as possible."
The letter follows a landslide that closed the northbound lane of the Princes Highway on the Kiama bends south of Kiama.
Northbound motorists have been asked to divert from Batemans Bay to use the Kings Highway to the Hume Highway.
