U.S. Route 56 - History

History

In the early 1950s, towns along what was then the K-45 corridor, connecting Ellsworth, Kansas to the Oklahoma state line at Elkhart, created the Mid-Continent Diagonal Highway Association to push for a new highway from Springer, New Mexico (on US 85) northeast across the Oklahoma Panhandle, along K-45, and continuing to Manitowoc, Wisconsin on Lake Michigan. By mid-1954, it was being promoted as U.S. Route 55 between the Great Lakes and the Southwest. The first submissions to the American Association of State Highway Officials (AASHO) to establish the route were made in 1954; all placed the northeast end at Manitowoc, Wisconsin (absorbing US 151 from Cedar Rapids, Iowa), while they varied on whether the southwest end was to be at Albuquerque, New Mexico or Nogales, Arizona. The first route considered in northeast Kansas was via US 40 from Ellsworth to Topeka and K-4 and US 59 via Atchison to St. Joseph, Missouri. A revised route adopted in March 1955, due to AASHO objections to the original route, which overlapped other U.S. Highways for over half of its length, followed K-14, K-18, US 24, K-63, K-16, and US 59 via Lincoln and Manhattan. In July, the US 50-N Association proposed a plan that would have eliminated U.S. Route 50N by routing US 55 along most of its length, from Larned east to Baldwin Junction, and then along US 59 to Lawrence and K-10 to Kansas City; towns on US 50N west of Larned, which would have been bypassed, led a successful fight against this.

However, in September of that year, the Kansas Highway Commission accepted that plan, taking US 55 east to Kansas City, Missouri. 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.

U.S. 56 originally took a different route between Boise City, Oklahoma and Elkhart, Kansas. The original route followed U.S. 64 east to an intersection south of Eva. It then split off to the north towards Elkhart. By 1961, the section north of U.S. 64 had been overlaid with State Highway 95. The following year, U.S. 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.
