Editing Interstate 29 (section)

=== 2019 closures ===

In March and April&nbsp;2019, as a result of the [[2019 Midwestern U.S. floods|2019 Midwestern US floods]], I-29 was closed in both directions for approximately {{convert|187|mi|km}} between [[St. Joseph, Missouri|St. Joseph]] and [[Council Bluffs, Iowa|Council Bluffs]]. Much of this section of I-29, including at the Missouri–Iowa border, runs over or through a large floodplain for the [[Missouri River|Missouri]] and [[Platte River|Platte]] rivers. As such, multiple elevated sections of the highway collapsed and other sections were submerged or washed out by floodwaters. This was the largest closure of an Interstate Highway in terms of distance in the history of the Interstate Highway System. A signed detour was not officially designated in most areas, as the roads that would be used as detours are mostly rural farm roads that were also submerged by flooding. However, along I-80 in Iowa, traffic from I-80 in Iowa was officially detoured via I-35 from Des Moines, Iowa, to Kansas City, Missouri. [[U.S. Route 75|US&nbsp;75]], paralleling I-29 on the other side of the Missouri River, was also closed in large sections due to flooding.

By May&nbsp;2019, the vast majority of I-29 had been repaired and reopened, with the exception of {{convert|10|mi|km}} around Council Bluffs where the highway ran concurrent with [[Interstate 680 (Iowa-Nebraska)|I-680]] (now the portion of I-29 between I-680 and I-880). However, throughout the remainder of the spring and summer, and even early fall, more rainfall and flooding resulted in sections of I-29 being closed again, including on the recently repaired sections. At a few times, the entire {{Convert|187|mi|km|adj=on}} section between St. Joseph and Council Bluffs was completely shut down, although this was rare after May&nbsp;2019.<ref>{{Cite web|url=https://www.3newsnow.com/news/2019-flood/stretch-of-i-29-closes-again|title=Stretch of I-29 closes again|date=October 6, 2019|website=KMTV|access-date=October 8, 2019|archive-date=October 8, 2019|archive-url=https://web.archive.org/web/20191008235352/https://www.3newsnow.com/news/2019-flood/stretch-of-i-29-closes-again|url-status=live}}</ref><ref>{{Cite web|url=https://www.omaha.com/news/public-safety/roads/flooding-closes-parts-of-i--i--near-council/article_5fc7b228-8105-5e72-98e9-fac34cd40e7b.html|title=Flooding closes parts of I-680, I-29 near Council Bluffs, Missouri Valley|first=Jessica Wade World-Herald staff|last=writer|website=Omaha.com|date=21 September 2019|access-date=8 October 2019|archive-date=8 October 2019|archive-url=https://web.archive.org/web/20191008235350/https://www.omaha.com/news/public-safety/roads/flooding-closes-parts-of-i--i--near-council/article_5fc7b228-8105-5e72-98e9-fac34cd40e7b.html|url-status=live}}</ref><ref>{{Cite web|url=https://www.kwit.org/post/flooding-again-closes-section-i-29-grassley-grandson-lead-iowa-house|title=Flooding Again Closes Section of I-29, Grassley Grandson to Lead Iowa House|first=Mary|last=Hartnett|website=www.kwit.org|date=7 October 2019|access-date=8 October 2019|archive-date=8 October 2019|archive-url=https://web.archive.org/web/20191008235400/https://www.kwit.org/post/flooding-again-closes-section-i-29-grassley-grandson-lead-iowa-house|url-status=live}}</ref>

As of October&nbsp;2019, all of I-29 is open to traffic in both directions, although some Missouri River bridges and local farm roads remain closed due to flooding.
