Listen to John Schmidt talk about street signs on Eight Forty-Eight
We've been having some fun recently with the technicalities of Chicago street names. Yet sometimes it's important to be precise. Take the matter of our busiest expressway.
Driving north on the Dan Ryan from the Skyway junction, you encounter a series of overhead signs directing you to the express lanes. The signs warn that if you enter the express lanes, your next exit is 22nd Street.
Chicago doesn't have a 22nd Street.
The city had a 22nd street until 1933. Then Mayor Anton Cermak was killed, and the name was changed to Cermak Road. In some of the western suburbs it's still called 22nd Street. But those towns are at least ten miles away from the Ryan.
Okay, most of the streets crossing the Ryan have numbers for names, so using "22nd Street" is just following that pattern. Right?
Except--Roosevelt Road isn't called "12th Street," and Pershing Road isn't called "39th Street."
