Interstate 35 in Kansas direction. After passing through the Kansas suburbs of the Kansas City Metro Area, it then crosses the state line into Missouri and into Downtown Kansas City. The original plan for Interstate 35 was to follow US 50 from Newton, as well as US 81 and US 177 to the Oklahoma state line. But when Kansas Turnpike was created, a part of Interstate 35 was created south of Emporia. The Newton segment was declined, and there was another implication for US 50 that traveled north (which is known today). The segments from Olathe to Shawnee was created by 1962. The relocations
K-126 (Kansas highway) K-126 (Kansas highway) K-126 is a mostly east–west state highway in southeastern Kansas. Its eastern terminus is the Missouri State Line east of Pittsburg where it continues as Route 126. Its western terminus is at U.S. Route 400 (US-400) just south of McCune. Between Pittsburg and US-400 this road was the original alignment for U.S. Highway 160. K-126 begins at an intersection with US-400 and heads northward; south of this intersection, the roadway continues as Northwest 100th Street. The highway passes the small city of McCune on its eastern limit, then meanders slightly to the northwest before turning north again.
