    I don’t think integrity after getting a support annihilated by a massive ship is a reasonable design objective. You’d need way more supports and structure, at least doubling the weight and cost of the structure, I’d guess maybe 4x. As far as stress tests go, getting one of your two supports knocked out is an extremely stressing condition.

      I learned recently that in engineering there’s a saying that anyone can build a bridge that will stand, but only an engineer can build a bridge that barely stands.

      Which seems dark, but bridges are built on budgets while adhering to aesthetic, material, and site/traffic (on, under, and sometimes over) requirements.

      And besides, that ship was between 210 to 257 million pounds, traveling at whatever speed it was going. I’m not a physicist, but I recon that’s enough force to knock down a bridge. (As evidenced.)

        Even moving very slowly, that’s a hell of a lot of force exerted on something designed to take a sideways load caused by, at most, wind.

      Bridges need therapists too!
