Harvesting logs (primary spanning elements) from the project site, we avoided transporting of bulk of our materials in on the trail – the concept itself detoured to meet a physical short-cut! When time expires the soundness of the logs, they can, with equal amounts of effort, be replaced. The imperative result is a high/low-tech hybrid that spans 30 feet – a middle ground between Roebling’s suspension bridge and a humble plank. We installed the deep v-shaped compression strut and cable assembly two thirds along the length, closer to the smaller ends of the tapering tree trunks. Like a bowstring, the braided steel cables were directed back to the end supports at either bank and tightened to push the sagging self-weight of the trees into an upward arching camber; delightfully firm underfoot. The steel components are thought to be durable enough to be reassembled and fit with new trees in replacement bridges in the future.
