Large Union County South Dakota acreage building sites! Opportunity generally knocks but once, amazing hilltop views on this bluff for miles from South Dakota across the Big Sioux River into Iowa. These sites have been asked to be purchased for years from many and have never left the family that homesteaded them, until now. Conveniently located in Union County South Dakota on HWY 48 gives good access and centralized between Vermillion, SD and Le Mars, Iowa (West to East) and Sioux Falls and Sioux City (North to South). Quick HWY access to I-29 within 10 minutes. Akron, Iowa is a quick 3 minute trip across the river for small town amenities and quick trips, banking, groceries, gas and more. Purchase one or both for nearly a 40 acre piece combined to build and live your happiness.
