Sioux Falls, S.D. (KELO-AM) - At the present time, the Arc of Dreams is only a dream but if a group of business leaders can make it happen, there will be a 70 foot high arch spanning the Big Sioux River in downtown Sioux Falls. The design of the stainless steel sculpture includes a 15 foot gap between the two halves of the arch. Fundraising starts with an initial goal of $650,000. Find out more at the sculpture walk of Sioux Falls website.
