I think you are thinking a different skyway. This one doesn't really go to any parking ramps, unless they are in the core.Shucks, we use that skyway to walk back to our parking ramp after Wolves games.
That skyway that will be taken down does go to the A ramp, (Hawthorn), as I've used it to get back to Hennepin after baseball games to avoid the crowds on the street after the games. Not sure how it benefits Target Center getting back to a parking ramp, But that skyway does connect with the A Ramp going towards Hennepin.
