Interstate 29, while in Iowa, hugs the east side of the Missouri River for as long as it forms the western border of Iowa. That means it enters the state in the very southwest corner of Iowa, running north through Council Bluffs to cross into South Dakota at Sioux City. Interstate 29 comes from Kansas City and St. Joseph in Missouri, and heads north into Iowa near Hamburg, Iowa. From there, it enters the metropolitan area anchored by Omaha, Nebraska and Council Bluffs, Iowa, where it serves as the main north-south Interstate Highway (despite the fact that it never enters Nebraska). It joins Interstate 80 west for a few miles, and along this concurrency, the eastbound and westbound directions are each split into separate collections of collector and local lanes, due to a fairly recent highway reconstruction. This is in Council Bluffs. Beyond Council Bluffs, Interstate 29 heads north on its own again, still just east of the Missouri River. It passes the eastern end of Interstate 480, the eastern end of Interstate 680, and the western end of Interstate 880. At Sioux City, Interstate 29 meets an interchange with another freeway carrying US Route 20, US Route 75, and Interstate 129's eastern extent. Interstate 29 curves westerly along side the Missouri River, which does the same, in Sioux City. This leads to Interstate 29's exit from Sioux City, and from the state of Iowa as a whole, on a bridge crossing over the Big Sioux River. Interstate 29's exit takes it into the far southeast corner of South Dakota.
For now, I'll just include a couple of photos. But I will soon get some more photos from the Interstates in Iowa so I can provide full exit lists for everyone. Those exit lists will have a photo for every exit. In the meantime, enjoy a short reel of photos.
First of all, though, here is the photo showing where I got my shield image for Interstate 29. It's a guide marker along Iowa Route 333 in Hamburg, Iowa!
