Thanks for writing. I live in Portage Park now and have been enduring six miles on Irving Park Road at those travel times for 5 years now. So, I definitely know how bad Irving Park can be.
I'm mainly wondering how much extra time it would add on to my commute to take the Kennedy from Elk Grove in order to get to that Irving Park exit. As I could then skip the travel time from Portage Park to that point on Irving Park Road, I'm guessing it may not be that much longer compared to the time I normally would've spent sitting at the Six Corners intersection anyway!
Would be great to know for sure from someone who takes that route on the Kennedy each day.
