And then there is=20 the issue of inspections and fixes cost money, and with a lack of that,=20 can imagine where that is headed - closed bridges, bottle necks, long=20 tortuous detours. :( To do an inspection correctly, requires competent=20 people crawling all over the structure from divers in the water to the=20 very highest point, measuring remaining material and condition, then=20 doing a structural analysis using current design criteria. The current=20 design criteria reflects more current knowledge of the materials,=20 usually indicates a more economical structure, but there have been a few=20 important failure items found over the years.
