Have you learned nothing from your time on this forum? Don't even mention pedestrian bridges downtown. 
half /s half serious

To be fair, even if it weren't ugly and useless, a pedestrian bridge across Gaukel would be a terrible idea.

Uh, why? Supposing it’s attractive and useful, what remaining problems are there with the idea?

That being said, in this particular case where if I understand correctly the question is how to connect accessible underground parking west/north of Gaukel with the main stadium east/south of Gaukel, it seems pretty obvious to me that the hypothetical stadium structure would continue right under Gaukel and people would just walk across at parking level underground. In this case I imagine the entire stadium having a single underground structure, partly public parking and partly “backstage” areas for the stadium itself.
