April 19, 2017: This sign, and the one beside it, are the oldest existing and last button-copy BGSs in Iowa. By the end of the year, the whole thing will be gone when a new alignment for westbound I-80 as it joins I-29 opens.
The Iowa DOT’s dedicated website for the Council Bluffs Interstate System project has an “online meeting” in the form of a slideshow. Many of the slides have short videos. What we’ll see in the coming construction season includes eastbound I-80 express lanes, although they won’t exist as such yet. The I-29/I-480 interchange still has two plans under consideration (PDF), all of which will involve either permanent closure of nearby partial interchanges or incorporation of them into frontage roads. That won’t even get under construction until the next decade.
