The large and only archway starting at Dayton Street near the football stadium.   I don't know the crux, but it's doable.

Archway

Is it Art ?

Nail's Tails

I thought it was concrete, but I was wrong; it has some on it but it's a rough plastic.  But I would say you could climb it or at least up to the tower of footballs and be alright.  Bring lots of pads.   It will take a lot of attempts to do anything.  If you have a long reach, this may help you.

There are two sections of art (football players' helmets carved into the wall near gate 8 and 9) reaching 10 feet high and 20 feet long each and you could boulder them. 

  Edges, crimps, and pinches are everything.  Bring some shoes and a spotter.

Distinguished by its impressive double-deck structure, Camp Randall Stadium has been the Badgers' facility since its opening game on Nov. 3, 1917. It has been host to UW football games, outdoor concerts, Drum Corps International, Green Bay Packer exhibition games, and other large public events.
