Member for Heathcote Maryanne Stuart said she was talking to Transport for NSW and the SES about the road's damage. She warned residents to stay at home until the route was made safe.
"Crews are on their way to assess that area and there is a commander from the Transport Management Centre going to have a look as well.
"I spoke to Wollongong City Council, and they have said the beaches are closed, and please stay at home. They are inspecting and cleaning up. Water is still coming down from the mountain area. Residents are keeping me informed, and I'm telling people to stay home and keep safe."
