Editing Interstate 29 (section)

===Missouri===
{{main|Interstate 29 in Missouri}}
Near its southern terminus, I-29 is concurrent with I-35 and [[U.S. Route 71 in Missouri|U.S. Route&nbsp;71]] (US&nbsp;71). The Interstate diverts from US&nbsp;71 just north of St. Joseph and follows a sparsely populated corridor along the [[Missouri River]] to Council Bluffs. During the design phase there was an alternative sending the route further along US&nbsp;71 through the bigger towns of [[Maryville, Missouri]], and [[Clarinda, Iowa]]. During the [[Great Flood of 1993]], the Missouri River flooded this section and traffic was rerouted to US&nbsp;71 through Maryville and Clarinda. I-29 was closed again for about two months during the [[2011 Missouri River Flood]].

Almost all of I-29 in Missouri is in an area called the [[Platte Purchase]] that was not originally part of Missouri when it entered the Union.
