Camden Bridges Update

The recent floods have significantly impacted a number of Camden’s Bridges. Works are underway to investigate the scale of damage, undertake repair works and reopen these assets to the community.

The damage caused is generally due to riverbank erosion or the collapsing of the riverbank adjacent to our bridge structures. There are various possible contributing factors as flood events over the past couple of years have seen the bridges repeatedly inundated.

This page aims to provide a summary of progress as relevant information is made available to Council.

We are working hard to reopen the bridges as quickly and safely as possible. We appreciate your patience.

Cobbitty Bridge

Cobbitty Bridge is located on the boundary between Wollondilly and Camden Local Government Areas.

Maintenance of the bridge structure is managed by Wollondilly Shire Council.

The roads on the approach to the bridge and the bridge have been closed since damage occurred following the July 2022 flood event, the largest flood of the past four events.

A large area of embankment on the Camden side of the bridge was part of a landslip into the river resulting in a large area of road collapsing.

Camden Council is working with specialist consultants to conduct investigations and design a suitable repair solution. It is difficult to estimate timing for expected repair works until more information is known.

Council will provide an update when more information is available.
