Project Completed

Stanley Street has re-opened to all traffic on 12 December 2025, with Townsville City Council wrapping up essential stabilisation works as part of a project dedicated to ensuring the safety of inner-city road users for years to come.

The $3.71 million Castle Hill Road and Stanley Street Slope Remediation Project, deemed necessary after the effects of the 2025 wet season, involved rockfall prevention and stabilisation works along the iconic hill-face.

The works, contracted to Shamrock Civil, saw unstable portions of the hill slope removed and re-shaped, as well as around 10 tonnes of rockfall mesh and 280 tonnes of shotcrete installed to stabilise the sites.

Project Background

Following recent pre-wet and post-wet season inspections of Townsville inner city hill slope stability, Council undertook rockfall protection and slope stabilisation remedial works along the Stanley Street cutting and Castle Hill Road.

As part of these works, Council:

removed unstable portions of the slope
shaped the remaining slope to a consistent grade
installed rock dowels, soil nails and rockfall mesh
applied shotcrete as required.

This project was part of Council's ongoing management of the heritage reserve and an outcome of our Castle Hill Reserve Emergency Management Plan (CHREMP). The CHREMP describes the processes and controls designed to ensure Council's compliance with its statutory obligations and to mitigate the risk of identified hazards to people, property, and the natural environment.
