Anyone with experience with eastern cedar poles as bridge girders?
We're building a simple bridge across a creek on the property for ATV and motorcycles. We built a railway tie crib in the middle of the creek and placed white cedar poles as girders. we'll deck it with oak slabs or maybe pressure treated decking. At the moment we have three poles per span. The poles about 12-14" big end sharply tapering to 6 to 8" at the small end. The span is about 18 feet. anyone with an idea of what weight poles like this can support?
