    I feel like the truss bridge design using rigid steel support structure was a bad one. For such a long span, it seems cable support is the safest because cables allow for some movement and the structure isn’t as rigid. If it weren’t the ship, an earthquake may have eventually cause the same outcome. That thing fell like a wet noodle upon impact of just one support column, seems like a really bad design. Should have built something like golden gate bridge.

      Most of these extremely long continuous truss bridges were built in the US in the 70s and 80s because they were pretty cheap for such a long bridge. And people have recognized that they are uniquely vulnerable becuase a single point of failure could potentially take down the whole bridge. However a lot of them haven’t had any retrofits to mitigate this issue.
