Significance
The bridge is a very rare example of timber king post truss bridges in Oregon. In the context of Eastern Oregon, it is the only example of its type. Simple designed, the resource demonstrates the primary elements of a truss bridge. The heavy timber frame is reinforced with knee braces and with riveted metal gussets on both the interior and exterior of the king posts. The floor beam is supported by steel tension rods, and the structure rests on concrete piers.
