Sawdust Bridge Replacement

Sawdust Bridge Replacement

This old, flood-damaged bridge across Don River in Tasmania needed to be replaced as it had reached the end of its useful life. Installed shortly after the opening of a nearby sawmill, the structure was prone to being impacted by floods and debris floating in the river.

The new bridge was designed as a single span frame, which goes directly from one side to the other. Harnessing prefabrication technology allowed the structure to be built off-site and installed in a matter of hours. Treadwell was engaged to provide the grating for the structure.

Project Challenges

  • Decking would be installed on a curved bridge structure and needed to accommodate the slopes.
  • Being in a remote area, the bridge would have to be airlifted by helicopter to be installed, as such, the material had to be lightweight.
  • The new bridge had to have a longer lifespan than the old wooden one, as well as require lower bridge maintenance.
