The branch routes of US 66:
US 166: Originally left US 66 at Baxter Springs, KS and connected to US 81 at South Haven, KS. The 1925 plan for US 160 left US 166 at Coffeyville and connected to US 75 at Independence. US 166 was extended east to Springfield, MO in 1945. It was truncated near Joplin, MO in 1966, the rest of the route is now I-44.
US 266: Originally left US 64 at Warner, OK and joined US 66 at Oklahoma City, OK, the same as the 1925 plan fro US 260. The half of this route west from Henryetta, OK was retired in favor of US 62 in 1931.
US 366 [I]: Originally left US 66 at Amarillo, TX and passed through New Mexico on its way to a southwesterly terminus at US 80 in El Paso, TX, the same as the 1925 plan for US 360. This US 366 designation was retired in 1931 in favor of the US 60 extension from Amarillo, TX to Clovis, NM and the US 70 rerouting from Clovis to El Paso, TX (currently US 54 from Alamogordo, NM to El Paso).
US 366 [II]: A new US 366 was assigned in 1931, taking over the route formerly known as US 470. US 366 left US 380 at Williard, NM to join US 66 at Albuquerque, NM. The portion of the route from Moriarty, NM was incorporated into US 66 in 1938, the remainder was decomissioned in 1939, now numbered NM 41.
US 466: The 1925 US 460 connected Los Lunas, NM to a point on US 70 near LaJoya, NM. US 466 was a 'reserved' number in 1926, the planned route was assigned US 85. A US 466 was finally assigned in 1934. US 466 left US 66 at Kingman, AZ and headed west, ending in Morro Bay, CA. This route was truncated at the California border in 1964, and fully decomissioned in 1971. Its route is now US 93 from Kingman to Las Vegas, NV; I-15 from Las Vegas to Barstow, CA; CA-58 from Barstow to Bakersfield, CA; CA-99 from Bakersfield to Famoso, CA; CA-46 from Famoso to Shandon, CA and CA-41 from Atascadero,CA to Morro Bay.

US 566: This route was added to the 1926 numbering, it was not in the 1925 plan. Originally left US 366 at Hondo, NM and connected with US 85 in San Antonio, NM. The US 566 designation was retired in favor of US 380 in 1931.
US 666: This route was US 560 in the original 1925 numbering scheme, US 560 was never used anywhere else. Originally left US 66 at Gallup, NM and terminated at US 450 (now US 160) in Cortez, CO.
