expressing a fascination with the relationship between function, technology and aesthetics in a graceful structural form

I really like the viaduct, but one thing I'm always wondering about when I read such take as one : can you show me how ugly it could have been ? Do we have others proposals for the same bridge where the engineers would have produced something without an architect and the result wouldn't have been a gracious mix respecting the landscape forms ?

I want to believe what's written. At the same time, I never got any proof for such sentences, it's always blurry, poetic, without any demonstration trying to minimize varying factors as scientist like to do.
