Is Interstate 80 open between Joliet IL. and Omaha ne?

Yes :) it goes until about the minden turnoff then near there you turn right then the road turns north when you get to Des Moins Iowa then it does right again then south then right and then after a while you will get to the town of joliet :) and it is aprox. 6 hours 58 minutes and 441 miles :)

I hope that helped. :) (Glad to help)
