Dallas (America's can't do city) spent $115,000,000 on a Santiago Calatrava designed dual arch suspension pedestrian and cycle bridge over the ditch that is the Trinity River. (Motor vehicle traffic is carried by a standard TexDOT highway bridge 'hidden' between the arches.) After ten years of planning and five years of construction the beautiful bike bridge was completed two years ago...but the state structural engineer has refused to certify the bridge is structurally sound because in certain wind conditions the support cables break away and pit&pendulum across the deck. So the bike bridge hasn't and can't be used and there is currently no plan or schedule in place to rectify the situation. As far as Dallas (America's can't do city) shakers and movers are concerned, that's okay, since they just wanted the arches for their addition to the city's skyline.
