Near its southern terminus , I-29 is concurrent with I-35 and U.S. Route 71 . The interstate diverts from U.S. 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 U.S. 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 U.S. 71 through Maryville and Clarinda . I-29 was closed again for about two months during the 2011 Missouri River Flood
