Same phrase as the paywall version which caught my eye: :...inspectors spotted a significant fracture in one of two 900-foot horizontal steel beams. " 900 foot beam? [Non USAians note that's 275 meters!] Is that a thing? Maybe welded like 'continuous rail'? otherwise how can a 900 foot beam be made at all? -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Even ship keels are many pieces. Here, it might be necessary to dive deep into the engineering terminology: Does a "beam" in bridge building necessarily have the proberty of being one continuous piece of metal, or is the bridge builder's "beam" only restricted to the meaning 'carries the forces of the road in a certain way', in contrast to a "frame"? As I never took any Engieering courses, I don't know the answer to this one. |

Caveat as I can not seem the images, but yes, you can 'construct' a 'beam' to what ever length you can manage. Bridges are commonly constructed with supports made from sections of "box beams" which are constructed from other lengths of 'steel'. Heck, they even make them out of concrete these days. |

Basically the same method, except these days they can build those in parts and ship them to the final assembly ship yard. Hint, there are some ewe tube stuff showing 'cut and insert' jobs to lengthen cruise ship. Something sort of related; to ships. https://www.youtube.com/watch?v=3m5qxZm_JqM |

They would also know that since that bridge goes over a river that a steel mill situated on a river would move capital beams via barges. It would never even occur to a normal brain that someone would move something like that on a road. |
