U.S. Route 66 in Kansas new Interstate highway crossed directly from Oklahoma to Missouri, bypassing Kansas entirely. US-69 Alternate was formed in 1985 when US-66 was decommissioned; the remainder of US-66 in Kansas became K-66. The final (1985) alignment of US-66 therefore perfectly matches present US-69 Alternate and K-66. Coming from the west, US 66 entered Kansas from Oklahoma, concurrent with US-69 Alternate, also called Military Avenue. From the state line, the highway ran north through Baxter Springs. At the intersection of US-66 with West 30th Street, the highway originally traveled east onto West 30th Street and then north onto Roberts Road to get back
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.
