Looking at the StreetView image within the vicinity of the project, the flooded land surrounding the Interstate looks ghastly: https://www.google.com/maps/@41.415052,-95.9001033,3a,60y,245.55h,76.19t/data=!3m6!1e1!3m4!1s5LPMsI9pFJtjektyFWID7A!2e0!7i16384!8i8192

That StreetView image justifies this road-raising project perfectly.

Wow, hope 2 feet is enough.

Good, we can't have a crucial piece of National infrastructure closed during it's peak season.... and it's going to only happen more often.

Wow, hope 2 feet is enough.

Until the next flood

Wow, hope 2 feet is enough.

Per the linked article, the aim is to bring the lowest point on that segment of I-29 to the same elevation as the lowest point on I-680, so that the former road is no longer affected by localized flooding.  For major flooding such as in 2011 and earlier this year, which destroyed parts of I-680 on both occasions, this is not going to help.
