Sturt River Linear Park Pedestrian Bridge
Sturt River Linear Park - NatureTREAD™
Sturt River Linear Park in the Coromandel Valley, South Australia is part of a 30 year masterplan for recreational activity for Greater Adelaide. The third stage was recently completed, allowing for easy and safe commute for pedestrians, cyclists and equestrian use. The future stage of this masterplan will see a continuous trail link all the way to the Patawalonga Basin in Glenelg North. Bridges were constructed at river crossings to provide the community with the opportunity to enjoy the views of the wildlife and rock foundations along the river.
Treadwell was engaged to design, engineer and supply three bridges, complete with collapsible handrail system for major flood events. This also included an additional boardwalk to complement one of these bridges.
Project Challenges
- The bridges are designed withstand 1:100 year flood events.
- The structure would be permanently exposed to the outdoor environment.
- The structure had to meet specific compliance codes.

NatureTREAD™
- Shear pin bolts were used on the Handrail posts stanchions. This allowed the railings to be collapsible in the event of flooding, minimising flood damage.
- GratEX® FRP Mini Mesh is constructed with an anti-slip surface, corrosion resistant properties and UV inhibitors. This allows for enhanced safety for the user, and assures structural integrity even in this exposed application.
- This structure was constructed according to the relevant compliance codes for pedestrians and cyclists.
- As FRP is easily modified on site without the need for any hot works permit, fire risk concerns are eliminated.
- Given the nature of FRP, any system utilising it is virtually maintenance free, keeping maintenance costs to a minimum.
