What the hell did I just read ? It was not bridges, but a single overpass that fell and it is unrelated to the ring or engineers. The main problem was that two governements failed to identify the weaknesses because they wanted to save money. I despise people like you who try to link two totally unrelated facts to sound smart.
My friend, this is just politics. This is a case of poor leadership trying to blame someone else for their own error (lack of investment in infrastructure). This as nothing to do with the iron ring.
