If you see it as a punishment to be the first to cross the bridge that you designed, then you should probably be increasing the factor of safety in your calculations and the number of site checks you conduct.
It's only a punishment if the bridge falls down. But if someone is making truck drivers drive heavy trucks out onto a bridge to "test" if it will stand up under the load it only seems fair to me that the engineers who designed and built it take the risk alongside them.
