I wish there was a good way to evaluate this claim. It comes from the American Society of Civil Engineers. I have nothing against them, but they are self-interested in this being a large number. The Key Bridge was structurally fine, but needed better protection so today’s ships couldn’t hit the bridge.

Just reading the article, the Key bridge was graded in Fair condition. There is no claim the bridge condition contributed to it collapsing when hit by a large cargo vessel. The ASCE report referenced (and linked to) in the article is 3 years old https://infrastructurereportcard.org/cat-item/bridges-infrastructure/ https://infrastructurereportcard.org/cat-item/bridges-infras... (2021 Report Card for America's Infrastructure). Their data comes from the US Department of Transportation. So there is no self-interest here, really.

Poor doesn't mean there's a significant risk of collapse, but replacements can take years and the bridge is approaching its end of life without corrective action. Even bridges in critical condition can be used safely with proper monitoring, just not for very long. https://en.wikipedia.org/wiki/National_Bridge_Inventory https://en.wikipedia.org/wiki/National_Bridge_Inventory POOR CONDITION - advanced section loss, deterioration, spalling or scour. SERIOUS CONDITION - loss of section, deterioration, spalling or scour have seriously affected primary structural components. Local failures are possible. Fatigue cracks in steel or shear cracks in concrete may be present. CRITICAL CONDITION - advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present or scour may have removed substructure support. Unless the bridge is closely monitored, it may be necessary to close the bridge until corrective action is taken. "IMMINENT" FAILURE CONDITION - major deterioration or section loss present in critical structural components or obvious vertical or horizontal movement affecting structure stability. Bridge is closed to traffic but corrective action may put back in light service.

You must be a software engineer to not understand that other engineering professions are actually professional. Which means that they have actual ethical standards which they must adhere to or have their credentials revoked.
