Took US 30 between Marshalltown and Cedar Rapids this week on the way back home from Denver and it looks like they'll have the last four lane gap filled by this time next year. When they do, that will makes US 30 a very attractive alternate to I-80 for me moving forward. Coming from Wisconsin, I will now be able to get to Des Moines and beyond on all four lane with way, way, way fewer trucks and other traffic with about the same travel time. It's a much more relaxing drive.
Still a slowdown by that casino west of Toledo and the run of stoplights leaving Des Moines on US 65. But everything else is pretty great. No worse than the signals one has to traverse in Dubuque or Marion. I think that will become my default path on any trip heading that general direction.
East Mixmaster construction is in full swing. Especially the new NB I-35 ramp. Seems like the biggest interchange project in Iowa since they overhauled the 29/80 commons in Council Bluffs.
