Locals should prepare for increased traffic during the middle of the day tomorrow (Friday June 24) when southbound lanes of Bulli Pass will be closed.
The Roads and Maritime Services will close the road between 10am and 2pm to ensure safety while essential maintenance is carried out.
That means traffic will be diverted down Lawrence Hargrave Drive at Helensburgh and through the Northern Illawarra.
Roads and Maritime Services will repair the safety ramp, which was damaged during the recent storms.
Large rocks and debris will be removed so the safety ramp can re-open.
