for those not familiar with Chicago, the bridges are up to seal off the downtown area. https://twitter.com/robertloerzel/status/1267131545875292162

really the only other time you see the bridges go up is a few weekends in the spring and the fall when rich people bring their big boats to or from the lake marinas via the river system.

I've lived in the area basically my whole life, worked downtown on and off, been to lots of protests and marches down there, and have *never* seen the bridges used as a crowd control mechanism.

Again, if you're not familiar. This is what the bridge system looks like. Downtown is essentially a peninsula if you cut the bridges off, accessible only from the south.

This is the current state of the busses and trains. Downtown is *also* cut off from public transportation.

And Lake Shore Drive is closed to downtown, both northbound and southbound.

the only example of this happening before in Chicago is literally fictional: they did it in the Batman movies filmed here. https://twitter.com/robertloerzel/status/1267187245984989184?s=20

Anyway, when your approach for dealing with protest mirrors Gotham's, you're fucked.
