[permaculture-oceania] Building Bridges

[Champagne]

Hi everyone,

Members of both BEND and Mumbulla Steiner School here in Bega are about 
to construct a small bridge that will allow easy movement for residents 
and students across a stormwater channel toward the Bega River. We need 
a design and the main criteria is that it remains when a flood comes 
through.

Its a 7 metre span with steep banks both sides. Anyone had any 
experience in this area or could direct me to a suitable web site?

Many Thanks
