Tomorrow night the Iowa DOT will hold an in-person information meeting in Cedar Rapids about six-laning part of I-380.
The meeting is at the DOT office near Kirkwood Community College at 5 PM. An “at your own pace” meeting will be available online after then. (And there better be PDFs.)
This project covers I-380 from near US 30 south to the Swisher/Shueyville exit, including the airport interchange. That interchange is going to be rebuilt into a diverging diamond, which would be the third in the Cedar Rapids area. I don’t think the project covers the US 30 interchange itself, which probably is going to have to be its own large project. Right now, there are only two lanes of traffic in each direction over 30, which would mean new bridges would have to be built.
