Back Creek footbridge replacement
South West Rocks

Background

The existing Back Creek footbridge was constructed in 1980 to replace the previous bridge at this location. The bridge is a unique asset within the Back Creek precinct at South West Rocks, providing for a range of community recreational activities including pedestrian access to the northern side of the estuary.

Bridge condition

In early January 2019, Council became aware that a timber component supporting the treated effluent pipeline on the footbridge had detached. The footbridge was closed to the public and repairs were undertaken to install temporary timber supports for the pipeline.

Council decision

A report went to the February meeting of Council outlining a range of management options. Council resolved to build a new footbridge rather than undertake interim maintenance works which it was estimated would be significant.

Project update

The design of a new footbridge maintains the form of the existing structure with the intent to preserve its heritage significance allowing water vessels to traverse from the estuary mouth to the boat-ramp upstream of the bridge.

Project complexity

The Back Creek footbridge replacement is a large project requiring significant planning, environmental investigation and project scheduling that will result in a lengthier than usual construction timeframe.

Council desires to maintain the open section of the existing bridge structure in a functional capacity while constructing the new bridge. This allows community use of the fishing platform however access to the northern side of the estuary is restricted until the new bridge is constructed.

This bridge construction project is in an aquatic environment meaning work will be dependent on tidal influence and climatic factors.

Construction timeframe

Fabrication of the bridge deck will commence off-site during August. Tenders have been awarded to undertake the bridge piling. It is anticipated that piling works will commence mid-September. Once piling is substantially started work crews will commence the construction of the bridge deck onsite in late September.

Once the new bridge has been constructed and safe for use by the public, the current timber footbridge will be removed and disposed of.

The construction of the new bridge is scheduled for completion by December 2019.
