Kansas City. On June 27, 1956, the AASHO Route Numbering Committee considered this refined plan for US 55, between Springer, New Mexico and Kansas City, Missouri, with a short US 155 along the remaining portion of US 50N from Larned west to Garden City. The committee approved the request, but since the proposed route was more east–west than north–south, it changed it to an even number – US 56 – and the spur to US 156. On June 26, 1958, AASHO denied the New Mexico Department of Transportation's request to extend US 56 west from Springer to Santa Fe, which would have followed US 85, US 84 and US 285. US 56 originally took a different route between Boise City, Oklahoma and Elkhart, Kansas. The original route followed US 64 east to an intersection south of Eva. It then split off to the north towards Elkhart. By 1961, the section north of US 64 had been overlaid with SH-95. The following year, US 56 was rerouted over SH-114, bringing it to its current diagonal path across the Oklahoma Panhandle. The old alignment is still on the Oklahoma highway system as the north half of SH-95.
