    Steel wires in the same plane (ie horizontal anchoring) as the horizontal segments could hold up even a single segment?

    I wasn’t aware they are there, how are they called so I can learn more?
    I’ve had a quick look at some schematics & didn’t find anything.
    Also afaik tensioned steel wires (prob not just on bridges) arent allowed to be hidden (at least in Europe) to allow for inspection.

      Well, they seem to exist. I recalling a news article where a pylon of a bridge broke, and the segments were held together by such a cable. It didn’t leave a usable bridge, but at least nothing big and more important nobody fell down.

      And whether they were hidden or not, I cannot give you an answer, but I think they could be accessible in the innards of the segments corpus, which in turn must be accessible anyway for inspection.

        Was it a proper viaduct like this one (tho this is a medium one, with roadways separated completely into two “bridges”) or a much smaller one?

        I’ll look into it when I have more time.
        (Tho the more I think about it the more I see a structurally unsound cable connecting the top pieces as a liability - it could be the cause for the collapse of the whole bridge instead of just the two sections in one & three on the order bridge … and if it could support the road then why not just beef up the cable & not use supports? … it might just not be possible)
