As one can see in the installation video from last weekend, the bridge in question was the first span of a larger project, in which at least one other span would have to be installed above an adjacent canal to complete the crossing. A rendering [1] shows the completed crossing to be an asymmetric harp-type cable-stayed bridge, with cables supporting both the portion above the road (the piece in question), and the piece that's yet-to-be constructed to go above the water. In this design, it's usually not possible to (temporarily) install the cables solely on one side of the tower, as the loads on one side of the tower would collapse the tower. Therefore, it stands to reason that the cables were either to come into play at the very end, or if the bridge were constructed by cantilevering out from the central tower and attaching cables as you go. In other words, without trying to pass judgment on the cause, the cables are either a red herring (because the sub-spans are self-supporting), or the bridge was assembled in a terribly incorrect sequence.
