The changed traffic conditions will apply from February, but some maintenance work will begin this week.
Maintenance work will be carried out between 7am and 5pm on weekdays from Tuesday, January 9 through to mid-April 2023, causing minimal impacts to traffic.
Work will be carried out under the bridge from a barge and will involve installing steel plates underneath the bridge supports.
As this work progresses, a reduced speed limit of 40 km/h will be in place across the bridge, 24 hours a day, and is expected to come into effect in February.
Motorists are advised to allow an additional five minutes of travel time, drive to the conditions and follow the directions of signs and traffic control.
The car park on the NSW side (adjacent to Miss Ross Hill) will be closed during this period while the area is used as a site compound.
Transport for NSW thanks the community for their patience during this time.
