A major highway linking the New South Wales Eurobodalla to the ACT will remain open today.
The Kings Highway has been closed for three days a week for the last four weeks for essential roadworks, and was meant to be closed today.
But Peter Meers from the Roads and Maritime Services says the heavy rain has forced detour routes to be blocked.
Mr Meers says the Highway will remain open.
"Palerang Council has advised that there's flooding that has caused them to need to close the Nerriga Road.
â??The rain has obviously played havoc with roads all over the region.
â??There has been a small rock fall, landslide, further down Clyde Mountain that was cleared up by Council staff last night."
