of the US 169/US 59/K-31 roundabout intersection and travels west and south on 6th Avenue from US 169 to US 59/K-31 (Maple St.) before turning south onto US 59/K-31 and running concurrently with them, ending at the US 169/US 59/K-31 roundabout intersection. At Osawatomie the road becomes a full freeway; as well as, running concurrent with K-7. In southern Johnson County 169 becomes an expressway until its junction with I-35 in Olathe. From this point to the Missouri state line, US 169 alternates between freeways and surface streets. It follows I-35 to Shawnee Mission Parkway in Overland Park, then travels east to Rainbow Boulevard. US 169 then follows surface streets to its junction with I-70 near downtown Kansas City. US 169 and I-70 enter Missouri together just after crossing the Kansas River. Missouri US 169 exits I-70 shortly after both roads enter Missouri via the Lewis and Clark Viaduct. It crosses the Missouri River by the Buck O'Neil Bridge and serves Kansas City Downtown Airport. Northbound, US 169 becomes a freeway at 5th Street south of the Missouri River, however southbound it ceases being a freeway north of the airport. An at-grade private driveway exists just south of the intersection with Route 9 as well as for airport access. At the northern end of the city an intersection is being reconstructed at NE 108th Street with completion in November 2013. Once this is completed it will be a freeway through I-435. This segment is also known as Arrowhead Trafficway, although this road neither passes nor approaches Arrowhead Stadium. US 169 is a four-lane rural expressway until it reaches Smithville, where it reverts to a two-lane rural highway. In St. Joseph, it forms most of the Belt Highway, a major commercial strip on the eastern edge of town, paralleling just inside I-29. US 169 angles northeastward out of St. Joseph, passing through many rural communities before exiting Missouri north of Grant City. US 169 intersects I-29 three times in Missouri: once in Gladstone, and twice in St. Joseph. Iowa US 169 enters Iowa just south of Redding. It intersects I-80 near De Soto. US 169 becomes an expressway at US 20, south of Fort Dodge. At Iowa Highway 7 on the northwest side of Fort Dodge it reverts to a two-lane highway again.
