Notes

Near its southern terminus, I-29 is multiplexed with I-35 and U.S. Highway 71. The interstate diverts from 71 just north of St. Joseph and follows a sparsely populated corridor in the Missouri River bottoms to Council Bluffs. During the design phase there was an alternative sending the route further along 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 71 through Maryville and Clarinda.

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

At its northern terminus, I-29 is multiplexed with U.S. Highway 81.

I-29 and its successor in Manitoba, MB Provincial Route 75 provide a direct route into Winnipeg.
