Route description edit

 

I-29 begins at I-70 in Kansas City in a concurrency with I-35 and U.S. Route 71 (US 71) at the Downtown Loop. 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 I-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. I-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 (89 km) south of Council Bluffs.

History edit

I-70 east to I-435 south was alternate a via route for traffic to void the 3 at-grade crossings.

During the 2019 Midwestern US floods, I-29 in Missouri was closed to traffic in both directions from St. Joseph to Council Bluffs, Iowa when the highway got flooded. It reopened to traffic by October 2019.
