I love to salvage things, especially wood. The bridges down here used to be made by taking a Corteza tree and using the log (often 30 meters long!) and dropping it across the river. Continue doing until you have enough, then tie together with cable. After that, fill with river rock and dirt.
Corteza is so hard it won't absorb water, so they last for years and years. It is actually cost effective now to replace it with a concrete bridge for the value of the wood!
We use the wood to make truck beds, outdoor chairs, corrals, etc.
