I will easily concede that bureaucrats and politicians are much less or not at all likely to evaluate alternatives in cost and risk objectively as private enterprise does in making investment decisions. It is very easy to throw all caution to the wind when you are spending OPM and making that to your advantage. Everybody in the public sector has a profound conflict of interest, no accountability to speak of and scarce background in things they preside over. The engineers they hire usually do consider many options and risk but they usually are not listened to or say little if they are in conflict with the politicians dreams if they want repeat business.
I have a cynicism about gooberment that comes from experience. Gooberment, politicians and bureaucrats seldom do anything right. "If the government were put in charge of the Sahara Desert in five years there would be a shortage of sand." I believe it. Owing to politicians gooberment is inherently flawed because of the kind of people politics attracts.
The bridge will be rebuilt but without the classic lines of the overhead through truss that was knocked down. In all likelihood it will be one of the cable stayed eyesores that are now economical and popular. What a shame. Hopefully this time they will not build such spindly angular hollow piers, space them further apart and in water so shallow a ship can't pass by them How about that for an idea? Maybe a 2,000 foot main span instead of 1,200 feet? The deepest water at the location is only about 50 feet and you can see the bottom at the last approach span piers. Much better protection structures could be built without much drama.
The state's estimate for the original structure was right at $60mm, the bids came in considerably higher with the ultimate cost of $110mm or so. I'd bet a lot that there were lots of conversations about just what parts of the original design were necessary. I'd bet those main span piers being angled and hollow and poorly protected was design-cost compromise. Upon first sight those piers struck me as odd and odder when I saw they are hollow reinforced concrete; downright spindly for such a large structure.
If there is concern about critical infrastructure bridges the one on I-20 and the old highway 80 bridge just upstream of it at Vicksburg is a lulu. I don't know how many times they have been hit by massive strings of barges at high water with high velocity. The old highway 80 bridge somewhat protects the main I-20 span. Somehow they have survived but it beats me just how that has been possible. There are NO pier protection cells upstream of either bridge on that one. Every hit on the bridge is a direct one. These are just one example of probably thousands of bridges across the nation and world at risk.
BTW, the Key bridge was hit by a ship shortly after the Sunshine Skyway bridge failure. This isn't the first time it has been hit but it is the last.
Especially in the era of DEI.
New York, Philly and Baltimore are doomed.
