Maintaining the bridge - Technology & maintenance - Sydney Harbour Bridge precinct
Project overview
As part of the commitment to maintain the Sydney Harbour Bridge, Transport for NSW conducts ongoing maintenance to ensure that this national icon is preserved for years to come.

Project information
Ongoing maintenance also includes repainting the bridge.
Updated line marking
We’ve enhanced line marking on the Sydney Harbour Bridge by repainting the lines between lanes 3 and 4, from the southern and northern approaches, and across the bridge road deck.
The updated line marking is longer and spaced closer together, matching the line marking already used between lanes 4 and 5. This will further assist motorists to recognise the area where the lane setup might be changed. Overhead signs will remain in place to show the current direction for each lane across the bridge.
Motorists should continue to follow traffic signs and speed limits.

Lavender Street Heritage Rail Bridge
As part of our ongoing monitoring and maintenance program, we’ve installed temporary scaffolding, a support structure, and sensors within the Heritage Rail Bridge, located over Lavender Street.
The sensors give us information about the bridge’s condition and will help to guide future maintenance work.
We’ll update this page with any key planned maintenance activities.
