The biggest equity problem with skyways is private ownership. If the skyways were municipal some of the biggest issues would go away. There is a bit of a problem with street life being kind of dead at the ground level, but I don't think that justifies ripping out skyways either.
I had to google wtf is a skyway and the thing going on in minneapolis with 90 of them seems extremely cool, I love them
The problem some people have with them is that they make the roads less pedestrian friendly by virtue of being a better alternative to walking on the sidewalk.
