Kansas City
The highway begins double- numbering in Kansas City, with Interstate 35 at Interstate 70 on the north side of the city center. From here, the 2×3 lane highway runs across a business park to the north. At the Gladstone enclave, the two highways split, I-35 running northeast to Des Moines, and I-29 running northwest to Omaha. After that, 2×2 lanes are available, passing through the northwest suburbs of Kansas City. One then crosses US 169, a highway to the northern neighborhoods.
Shortly thereafter, it crosses Interstate 635, Kansas City’s western bypass. After that, 2×3 lanes will be available. After 25 kilometers one crosses State Route 152, an east-west highway in the north of this sprawling city. Then you leave the built-up area, and you pass the international airport of the city. Here one crosses the Interstate 435, the Kansas City ring road.

Northwestern Missouri
The highway then has 2×2 lanes, and you pass through slightly sloping area which is fairly overgrown, in contrast to areas further north and west. I-29 runs due north, more or less parallel to the Missouri River. About 60 kilometers after Kansas City you reach Saint Joseph, a regional city with 74,000 inhabitants. This is where Interstate 229 branches off, which runs through downtown St. Joseph. A little further on you cross the US 36, which forms a highway here, and forms the road between St. Joseph and Hannibal. There are just 2×2 lanes along St. Joseph, and I-229 rejoins on the north side of town.
North then goes to US 71, which runs to Maryville. The I-29 curves here to the northwest. One passes through an area that is a mix between agricultural fields and small forests. There are only a few villages on the route. The highway sometimes runs close to the Missouri River, which meanders through the landscape. Near the village of Rock Port, the US 136 crosses, which runs from Auburn in Nebraska to Maryville in the east. Not far after that, just south of Hamburg, they cross the border into Iowa. Interstate 29 in Iowa then continues to Council Bluffs and Omaha.
History
As with most Interstate Highways in Missouri, construction on I-29 got off to a good start. Part of the route, before it became an Interstate, was already a 2×2 US 71, at least from the north of Kansas City past the airport to Platte City. This part was opened around 1954, but it is unknown whether it was already a full-fledged highway at that time, or whether it was upgraded in the mid-1960s. The old Paseo Bridge over the Missouri River in Kansas City also opened to traffic in 1954, and was a toll bridge at the time. The highway reached St. Joseph as early as 1961, the first highway between two major Missouri cities to be completed. In 1964, the St. Joseph route opened, relieving 2×2 US 71 through east St. Joseph and avoiding a series of traffic lights. Then construction slowed down, and stretched quite well into the 1970s. In 1973, the northernmost section opened between Rock Port and the Iowa border. The last link was between Craig and Rock Port and opened to traffic in 1977. On September 27, 2010, the new Christopher S. Bond Bridge opened replacing the old Paseo Bridge. This is toll-free.
