Sioux City Journal: The Port of Blencoe, which officially opened Wednesday, has already seen a few barges in and out of that stretch of the upper Missouri River for the first time in over 15 years. Western Iowa farmers now have access to a lower-cost option to receive fertilizer and to export grains at the new “gateway to the world market.” NEW Cooperative constructed an $11 million port along the Missouri River near the small Monona County town of Blencoe, which is about halfway between Council Bluffs and Sioux City. It is the northernmost port on the nearly 760-mile span of the Missouri from St. Louis to Sioux City.
