"Longview Bridge, Port of Longview and Mt. St. Helens, Washington. Located 66 miles upstream from the mouth of the Columbia River is one of the finest inland ports in the nation. This bridge spans the Columbia and connects Longview to Rainier, Oregon. Magnificent Mt. St. Helens in the background."
Probably from the 1970s, and definitely before Mount Saint Helens blew up in 1980, losing that nice pointed cone top.
