Sawn Timber Demountable Bridges

Our demountable range of bridges based on sawn timber was designed for the needs of National Parks.

Bridges built on logs are unsuitable for this application as the logs can weigh in the vicinity of one tonne each and need good crane access.

Demountable bridges are suitable for spans up to 5 metres (6 metres with the Barup truss option) sited on remote bush tracks where every item must be carried to the site.

The heaviest component on the longest bridge weighs 120kg.

The kit, manufactured from selected hardwoods is supplied with:

• All timber cut to length
• Major bolt holes pre-drilled
• Decking pre-drilled
• Timber treated after pre-working
• All hardware
• Foundation reinforcing, boxing and pegs
• Sacrificial back wall timbers
• Assembly instructions

See examples of our bridges from our Bridge Project Galleries
