Bridge over the Middle Fork

On the Pacific Crest Trail, where it crosses the Middle Fork of the Feather River in the vague northern part of the Sierra Nevada, California. It's a rather substantial bridge for just a footpath! It's also a ways from the nearest road, so it must have been quite a chore to get the materials in to build it. The Middle Fork is a designated "wild and scenic river," so there are no dams or other control structures.
