About eight years ago, I added an “Iowa border bridge timeline” into the Annex section. It has a bar chart of Iowa’s bridges across the Missouri and Mississippi rivers. At the time, I stopped the lines in 2010, knowing the new US 275/IA 92 bridge was going to open then.*
Now, with the I-74 bridge replacement included in the five-year plan — a step up from “real soon now”, and two steps from “eventually” — I can draw the timeline out to 2021. I’m going to treat the new I-74 spans as replacing their respective ones, rather than one new one. This is in part because the new bridge will be open in stages, with one old span scheduled to be closed around Thanksgiving 2019 and the other to stick around for a year longer.
*I know that there are no pictures for that new bridge yet on the site. The ones I have, from one visit, aren’t good enough.
