Description 

While timber stringers are a common sight in the Northwest this one was a part of the Weyerhaeuser Company's vast network of roads and timberlands. This existed for the sole purpose of transporting product from clearcut to lumber mill without having to use public roads, the example here WA (formerly US) 410. Using their own roads meant that they could stack the loads as high or as wide as they wanted. Other bridges in the area included concrete tee-beams, slabs, and at least one pony truss. Weyerhaeuser is no longer the active player in the timber business as they once were having closed their mills and divested their properties to conservation groups, rivals, or developed by themselves in their current strategy housing developments.
