Tidbinbilla Bridges

To complete a couple of loops of multi-use track around Webbs and Jedbinbilla at the Tidbinbilla Nature Reserve, we designed and constructed two bridges over the Tidbinbilla River. One 8m clear span and one 9m clear span.

There were many challenges associated with both sites.  Access was the major one.

Constructing a bridge with a clear span of 9m by hand is challenging enough but to do it with NO machinery assistance could be deemed too hard.  Then add a river into the mix and it would have been easy to label this project as impossible.  We found a way and the results are stunning.

The 9m bridge was designed with modular construction in mind that enabled us to safely carry in and construct the bridge without the use of machinery.  The bridge is made up of an aluminium structure and handrails, and a non-slip composite decking ideal for this application.  The construction of this bridge took 5 days.

By contrast, the 8m bridge was constructed near the site and we employed the use of a 70 ton crane to lift it into position in its fully assembled form.
