Why are you taking 88 to Peoria? Maybe you meant to say 80 which seemingly always has construction.
And to the OP, they took a bus out of the greyhound station down by UIC but I'm not sure which bus line. Peoria isn't a great walking town but you should be able to make it work since you will be downtown Peoria. My dad actually went to the Peoria campus for med school so you will have to let me know how it is! Good luck!
Well I go to school west of Peoria, so I take 88 to the quad cities then go south. But whenever I go to Peoria instead I take 88 to 39. I think the distance is about the same but maybe I just do it wrong.
