A bridge to nowhere hovers above the Circle Interchange, remnants of the Ryan-to-Eisenhower ramp.

Anybody remember that time I said construction on the Jane Byrne Flyover was silent?

Yeah, well that was construction. Let’s talk about demolition for a minute. Because for every reaction, there’s an equal and opposite reaction. Granted, the reaction usually comes first. As in, something is demolished to make room for something new. But in this case, the ramp that used to connect the inbound Dan Ryan Expressway to the outbound Eisenhower Expressway was replaced before it was removed. Which crews are doing now. And for some reason, they’ve chosen to do a great deal of the jack hammering at night. Or should I say, overnight. Not a huge thrill for denizens of the West Loop, South Loop, and the Medical District. Part of that has to do with removing the beams over the expressway lanes at night, when there’s less traffic to be affected by periodic closures. But it’s loud. Really loud.

You’ll note in the photos that follow the presence of caisson equipment, including rebar cages. I can’t wait to see what that’s all for.
