September 30, 1970: Initial construction stage of the I-80/I-380/US 218 interchange in Johnson County, via Iowa Geographic Map Server. It was built as a cloverleaf, but US 218 to the south would come after I-380 opened.
You know it’s important when there’s going to be a formal presentation.
On Monday in Coralville, the Iowa DOT is going to have a public meeting regarding the complete reconstruction of the I-80/380 interchange that will last until the end of 2024. This meeting is for what’s going on this year; there will be similar meetings every spring. There’s some information about the overall project at a website set up specifically for it, but the press release says more will come Monday. (The press release messed up the weblink; here’s the correct one.)
Initial construction focuses on the Forevergreen Road exit, which will be needed as a relief valve, and the first flyover ramp from eastbound 80 to northbound 380 (the most important one).
This project adds to the list of ongoing multi-year major projects that are reshaping pieces of Iowa’s interstate highway system for the first time since their initial construction (Council Bluffs, Sioux City, and I-74).
