We finally hooked up with two "Follow us and ignore the 'road closed ahead'" salesmen who got us on the right track.
That all said - the flood devastation around I-29 was astounding.
Yes, the flood damage was a sight to be seen. Sorry about the road signs... we had people coming here in early July, they were going to come on I-80 then the 680 North loop to come into Omaha for Fort St. There were no signs at the exit to 680 from westbound I-80 in Iowa; the people came 20 miles before finding a sign saying they had to turn around and go back to I-80 into Omaha due to the roads and bridge being closed.
