Interstate 29 (I-29) is a north–south Interstate Highway in the Midwestern United States that begins in Missouri. It travels through the Kansas City and St. Joseph metropolitan areas before exiting the state and entering Iowa. Almost all of I-29 in Missouri lies in an area called the Platte Purchase that was not originally part of Missouri when it entered the union.
Interstate 29 begins at Interstate 70 in Kansas City in a concurrency with Interstate 35 and U.S. Route 71. It crosses over the Missouri River via the Bond Bridge. I-29 and I-35 separate in northern Kansas City, with I-29 turning northwest with US 71 running concurrent with it. It passes near Kansas City International Airport, and near there is concurrent with Interstate 435. I-29 then exits the Kansas City area. It enters the eastern portion of St. Joseph while downtown St. Joseph is served by I-229, a loop of I-29. After exiting St. Joseph, US 71 separates from I-29. Interstate 29 then passes through rural areas of northwestern Missouri on a southeast-to-northwest alignment, then crosses into Iowa north of Rock Port, approximately 55 miles south of Council Bluffs.
