Location: HMP 34.3

Builder: The Construction Company, Portland

This four-span 80-foot reinforced-concrete deck girder trestle is 24 feet wide and has a roadway measuring 22 feet. The curb and guardrail form an integral unit, cantilevered out from the outside deck girder. The delicate arched railing panels were constructed from plaster concrete and metal lath, and are identical to those seen on the Multnomah Falls viaducts. A staircase at the western end leads down to the creek, where visitors were encouraged to walk upstream 0.5 miles to view Oneonta Falls.

There is some suggestion that the falls might have been visible from the highway, or at least the mouth of the gorge, before the view was blocked by the massive log jam blocking the mouth of the ravine today.

The photo above, from Charles W. Post, does not rule this out, it seems like there might be some faint glimpse of the falls at the end, but this copy of the photo, from Mershon's book, is so small and grainy that it is difficult to tell for sure.
