The Dunes could/can not stop the bridge from being built as it will connect to the trail which is on public land. They could have said no to their part of the funding, a measley $50,000, which is not much compared to what Sioux City has to raise for the remainder of the $500,000. In all honesty I would rather have had the Dunes say no to their $50,000 to have the bridge built where it should be, dorectly connecting both trails to one another. In the grand scheme of things the 50 grand is not a whole lot of money.
