I get steamed about this kind of crap. These bridges and sidewalks are bare minimum mobility for people screwed by freeway infrastructure. www.minnpost.com/cityscape/20...
Agencies and governments turn to fencing instead of actual solutions for problems related to people experiencing homelessness.
Prediction: having closed the 24th St bridge some of the homeless people will move down to the Sabo bridge, which is an even more important link (I'll be happy to be wrong, and there's no easy answers to this problem)
