It’s obvious I’ve got some savvy Chicago natives reading this blog, so maybe y’all can help me comprehend the incomprehensible, as my Google-fu has failed me:
How the heck do they switch the direction of the Interstate express lanes?
I understand they’ve got a series of gates at the entrances to the reversible lanes, which swing shut to keep traffic from pouring into them. But given the non-stop nature of Chicago highway traffic, how do they clear those entrance ramps long enough to shut the gates? At virtually any given moment, it seems like there’d be someone driving into the entrance, who’d unavoidably smash through one or more of the closing gates. How do they do it??
