Motorists are advised of the closure of Lady Wakehurst Drive between McKell Avenue and Otford Lookout for maintenance work next week.
Work will include general maintenance, guardrail repairs, trimming vegetation and clearing gutters and drains to improve safety.
The road will be closed in both directions between 8am and 3pm, from Tuesday 2 May to Thursday 4 May, weather permitting.
Detours will be in place via McKell Avenue, the M1 Princes Motorway and Lawrence Hargrave Drive and are expected to add about 10 minutes to journeys.
Access on foot to Otford Lookout and walking tracks to the beaches in the Royal National Park will not be affected by the closure.
Motorists are advised to drive to the conditions and follow the directions of signs and traffic control.
Transport for NSW thanks motorists for their patience during this time.
