This is for Illinois and not Iowa, but it will be notable in the future for interstate drivers. A small portion of I-490, the long-promised west bypass of O’Hare airport, opened a few weeks ago (WMAQ). It is part of the Illinois Tollway system and right now just runs between Franklin Avenue and I-294 (NB exit/SB entrance only).
In 2027, according to the news story, another segment will open extending north from Franklin to what’s currently IL 390 (formerly the Elgin-O’Hare Expressway before the ISTHA took it over, maybe I-390 at some point in the future). Much of this portion is bridges over railyards.
Far more importantly than just being the start of a connection to a future western O’Hare terminal (according to Wikipedia), the opening ruins my complete clinch of Illinois’ interstates. If it had opened a month earlier I could’ve covered it!
