Sydney Harbour Bridge

Sydney Harbour Bridge precinct

Transport for NSW has a coordinated approach to the continuous improvement and maintenance of the Sydney Harbour Bridge.


Transport for NSW will be closing some lanes of the Cahill Expressway over the Sydney Harbour Bridge from 1am Saturday 11 June to 4.30am Tuesday 14 June 2022 (weather permitting). During this time, we will carry out essential work to install new medians between lanes 6 and 7, improve drainage, and resurface lanes 7 and 8.

We are taking advantage of lower traffic volumes during the long weekend to complete work.

The speed limit on the Sydney Harbour Bridge will be reduced to 40 km/h in both directions during this work.

In all the work required to look after, improve and adapt the Sydney Harbour Bridge to the needs of a modern city, Roads and Maritime is committed to preserving the beauty and character of the structure and its setting.

Urban design, traffic, pedestrian, public transport, safety and maintenance projects all work together to support an average of 204 trains, 160,435 vehicles and 1,900 bikes per day (based on September 2010 traffic count figures).

Roads and Maritime continues to update customers on work being carried out on the Sydney Harbour Bridge.

Conservation Management Plan

A Conservation Management Plan for the Sydney Harbour Bridge has been prepared to provide a framework for its ongoing care and management. This includes decisions about conservation, use and development.
