We have a 4m bridge spanning a small river in our garden: nothing fancy, just concrete 'foundations'* built into the banks supporting (small) steel I-Beams across the span of the river, and then a flat timber bed on top of the I-Beams. The timber has deteriorated now to the point that I need to replace the whole deck.
What would be the best wood to use that is a combination of being naturally resistant to rot, strong and 'attractive' when new and aged state? The 40 timbers that are present at the moment are dimensions 1800mm x 100mm x 50mm. So not huge: expense is not so important as appearance, longevity and strength, as the load bearing needs to be able to accommodate my 90kg bulk perched atop a Countax garden tractor towing a 79 litre spraying bowser! Maybe north of 300kg in total.
*the foundations have been scoured out by the water over the years, so it's an opportunity to strengthen those whilst the deck is off, but that is another story...
Thanks for any advice
