History The original southern terminus was at Atoka, Oklahoma at an intersection with U.S. Highway 75. From the creation of the highway in 1926 until April 11, 1935, US 73 was split between Oswego, Kansas and Horton, Kansas. US 73E followed modern US 160 from Oswego to Columbus, then modern US 69 to Kansas City, where it then latched onto what is now US 73. The US 73E designated then went from Kansas City to Horton. US 73W followed the route of modern U.S. Route 59 from Oswego to K-39, K-39 west to Chanute, modern U.S. Route 169 from Chanute to Garnett, modern US 59 again from Garnett to Nortonville, and then modern U.S. Route 159 from Nortonville to Horton. On April 10, 1935, US 73 was truncated at Kansas City with the modern designations taking over the old routes and US 69 taking over the Atoka-Oswego
