Renewal of the Canning Bridge Riverwall
A major feature of the City’s foreshore in Applecross is the riverwall near the Raffles Hotel. The foreshore in this area includes a vertical stone wall and rock revetment which provides protection to a shared path, landscaping and the Raffles Hotel. The wall also provides protection to the western abutment of the Canning Bridge.
In 2014, the City engaged an engineer to undertake an audit of the riverwall as there were issues with sinkholes and pathway subsidence. It was recommended that further geotechnical investigations were conducted to better understand what was causing the problems.
The geotechnical investigation was completed in 2016 and it found that the key issues with the riverwall are;
- erosion of soil through gaps in the mortared joints in the wall;
- possible failure of geotextile behind the wall and;
- some localised sinkholes and subsidence of material directly behind the wall.
The project will cost approximately $600,000 and has been set aside in the 2019/20 financial year budget.

In order to progress with the repairs or replacement of the riverwall, the City engaged a specialist coastal engineer to undertake the design and documentation of the riverwall renewal.
As part of the project, the City will also;
- renew the landscaping and;
- improve the river revetment to the east side of the bridge
Access along the shared use path in front of the Raffles will be closed for the duration of the works, however, access under the bridge will be closed only for approximately 4 weeks while works including revetment and resurfacing are completed.
