To keep cost down and ease construction, the design was reverted back to using concrete for the structure instead of steelwork arches. (Reina, 2004) * Structural design flaws:

* Berthier's report pointed to four connected causes: 1) insufficient or badly positioned structural steel; 2) lack of mechanical "redundancy," in that the stresses were concentrated and could not be shifted to other structural components; 3) concrete beams that offered too little...
