Chicago Avenue Bridge
Posted June 18, 2018, by Roger Deschner (rogerdeschner [at] gmail [dot] com)

104 year old bridge is listed for sale - but only for a couple of weeks. This looks like another City of Chicago gambit to circumvent Section 106 as fast as possible, just like with the nearby Division Street Bridge, right now! Demolition of this historic structure is likely very soon.


Why couldn't the City just maintain it, instead?
