Interstate 29 is a major highway which runs north to south. It starts at Interstate 70 in Kansas City in the same places as it follows Interstate 35 and the US Route 71. The road goes over the Bond Bridge to cross the Missouri River and St Joseph and here it separates from I-35. When it gets to northern Kansas City it turns north west still adjacent with US 71. They pass near the Airport where it runs alongside Interstate 435 and then exits the Kansas City area and moves into the eastern part of St Joseph. It then separates from US 71 and goes through rural areas of north west Missouri working on a south east to north west round and then leaves the state and moves into Iowa at a point that is north of Rock Port. Most of this highway is in an area called the Platte Purchase which wasn’t originally part of Missouri.
Interstate 35 stretches from the north to south of the United States from Texas in the south to the Minnesota Highway 61 in the north which can then take you on up to Canada.
Interstate 44 stretches from the north east in Illinois at the state line on Poplar Street Bridge which is over the Mississippi River in St Louis. It was built to bypass route 66 and goes all the way down to Oklahoma City. Most of the route was once US 66 but has now been upgraded to four lanes. The only part that isn’t is the section west of Springfield which was moved farther south to connect the section is Missouri with the Will Rogers Turnpike.
