The South Yamhill River valley serves as a bustling industrial corridor in the mid-1950s, anchoring the timber and transit hubs of Sheridan and Willamina. This survey captures the region just as the modern road network was taking its permanent shape, with sections of the Salmon River Highway and Dallas Coast Highway marked as under construction. Large millponds reflect the heavy reliance on the lumber industry, while the Southern Pacific and Longview Portland and Northern railroads provide the essential logistical links to the broader Oregon market.
