The DOT’s “I-80 Planning Study Public Meeting #2” video, about 11 minutes long, is online. It has had fewer than 400 views since being uploaded to YouTube a month ago. Perhaps I can help with that:
For some reason, all the animated maps highlight I-80 following I-235 through the Des Moines area.
The video says that four-laning US 30 and US 34 instead of six-laning I-80 across Iowa would not do enough to relieve traffic on the interstate. The last third of the video diverts to discussion about automated vehicles and their long-term effects on interstate planning.
