Why did Chicago widen Ashland Avenue?

If you pay attention to street signs in Chicago, you’ll notice imperfections and many quirks. Paul Durica of the Chicago History Museum said a coworker informed him that North Avenue becomes North Boulevard when you’re east of Clark Street. “And I was like, what?” Durica recalled. “And it does! And it's because here we are, now in the park.” One of Chicago’s major arteries, Ashland Avenue, has a rich history of its own. In our last episode, we looked at why streets like Ashland are occasionally labelled boulevards (like North Boulevard, sometimes the answer is because the street is adjacent to a park). Today, we’re looking closer at the history of Ashland Avenue, including how it became a major thoroughfare and why the city widened it at great expense 100 years ago. (The short answer? To accommodate car traffic.) Contributing are Durica and Northwestern Professor Bill Savage, author of a forthcoming book on the anomalies and politics behind Chicago’s grid system.
