I just checked google map they say about 40min,. I'd say at least 40 min or more. I live in Lakewood and I'm 40 min away using the shore way (6). I used to commute from Amherst to downtown. Amherst is 10 min further West of Avon. The freeway (I 90) is 3 lanes starting at Avon (rt 83), you get some 4 lane even 5 lanes downtown. To go to Case you have to get off at Chester Ave downtown and drive 3 miles on a surface street. That will suck. I 90 is the easiest freeway to use into downtown of all of them (77,71,90e). In the winter or if there is an accident you can double the time but only about 10 times a year, at least lets hope. The hard part will be from nearing the downtown area(the inner belt) to University Circle (Case).
For me personally that would be a tough drive, but people do it everyday and in other cities that would be nothing. But then I live in Lakewood and drive 15 min to downtown.
