Question: What is an alias of the parent route of U.S. Route 366?

full_context: Document 1: U.S. Route 66 in Missouri: U.S. Route 66 (US 66, Route 66) is a former east–west United States Numbered Highway, running from Santa Monica, California to Chicago, Illinois. In Missouri, the highway ran from downtown St. Louis at the Mississippi River to the Kansas state line west of Joplin. The highway was originally Route 14 from St. Louis to Joplin and Route 1F from Joplin to Kansas. It underwent two major realignments (in the St. Louis and Joplin areas) and several lesser realignments in the cities of St. Louis, Springfield, and Joplin. Current highways covering several miles of the former highway include Route 100, Route 366, Route 266, Route 96, and Route 66. Interstate 44 (I-44) approximates much of US 66 between St. Louis and Springfield.
Document 2: U.S. Route 366 (1927–1932): U.S. Route 366 or US 366 was the designation of two child routes of the former U.S. Route 66 in New Mexico and Texas during the late 1920s and 1930s. Both alignments of US 366 were original U.S. Routes created in 1927. The first alignment was a route from El Paso, Texas to Amarillo, Texas crossing through New Mexico that existed until 1932. The second was a route from Albuquerque, New Mexico to Willard, New Mexico that was previously assigned a different route number before 1932. That alignment was canceled in 1939.
Document 3: Lincoln Highway: The Lincoln Highway was one of the earliest transcontinental highways for automobiles across the United States of America. Conceived in 1912 by Indiana entrepreneur Carl G. Fisher, and formally dedicated October 31, 1913, the Lincoln Highway ran coast-to-coast from Times Square in New York City west to Lincoln Park in San Francisco, originally through 13 states: New York, New Jersey, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Nebraska, Colorado, Wyoming, Utah, Nevada, and California. In 1915, the "Colorado Loop" was removed, and in 1928, a realignment relocated the Lincoln Highway through the northern tip of West Virginia. Thus, there are a total of 14 states, 128 counties, and more than 700 cities, towns and villages through which the highway passed at some time in its history.
Document 4: List of state routes in Nevada prior to 1976: Nevada's original State Routes were developed beginning in 1917 upon the creation of the Nevada Department of Highways. Route numbers were not assigned according to any particular numbering system, and sequential numbers were often scattered throughout the state. For example, while State Routes 27 and 28 were designated along highways near Lake Tahoe in northwestern Nevada, State Route 29 connected to Death Valley in central Nevada and State Route 30 was connected to Utah in northeastern Nevada. Additionally, several suffixed highways, branching from the original parent route, were also designated. The numbering of state routes was designated in state laws by the Nevada Legislature (codified in the Nevada Revised Statutes in later years); this had the side effect of many routes not being fully owned or maintained by the state.
Document 5: U.S. Route 101 in California: U.S. Route 101 (US 101) in the state of California is one of the last remaining and longest U.S. Routes still active in the state, and the longest highway of any kind in California. US 101 was also one of the original national routes established in 1926. Significant portions of US 101 between the Los Angeles area and the San Francisco Bay Area follow El Camino Real, the historic road connecting the former Alta California's 21 missions.
Document 6: U.S. Route 366 (1932–1939): U.S. Route 366 or US 366 was the designation of two child routes of the former U.S. Route 66 in New Mexico and Texas during the late 1920s and 1930s. Both alignments of US 366 were original U.S. Routes created in 1927. The first alignment was a route from El Paso, Texas to Amarillo, Texas crossing through New Mexico that existed until 1932. The second was a route from Albuquerque to Willard that was previously designated U.S. Route 470 before 1932. That alignment was canceled in 1939.
Document 7: U.S. Route 61: U.S. Route 61 (US 61) is the official designation for a United States highway that runs 1400 mi between New Orleans, Louisiana, and the city of Wyoming, Minnesota. The highway generally follows the course of the Mississippi River, and is designated the Great River Road for much of its route. As of 2004, the highway's northern terminus in Wyoming, Minnesota, is at an intersection with Interstate 35 (I-35). Until 1991, the highway extended north on what is now Minnesota State Highway 61 (MN 61) through Duluth to the Canada–US border near Grand Portage. Its southern terminus in New Orleans, Louisiana, is at an intersection with Tulane Avenue at South Broad Street. The highway is often called the Blues Highway because it connects Saint Paul, Minnesota; St. Louis, Missouri; Memphis, Tennessee; the Mississippi Delta, and New Orleans.
Document 8: U.S. Route 491: U.S. Route 491 (US 491) is a north–south U.S. Highway serving the Four Corners region of the United States. One of the newest designations in the U.S. Highway System, it was created in 2003 as a renumbering of U.S. Route 666 (US 666). With the 666 designation, this road was nicknamed the "Devil's Highway" because of the significance of number 666 to many Christian denominations, which is believed by some that 666 is the Number of the Beast. This Satanic connotation, combined with a high fatality rate along the New Mexico portion, convinced some people the highway was cursed. The problem was compounded by persistent sign theft. These factors led to two efforts to renumber the highway, first by officials in Arizona, later in New Mexico. There have been safety improvement projects in recent years, and fatality rates have subsequently decreased.
Document 9: Billy Connolly's Route 66: Billy Connolly's Route 66 is a British travel documentary television series presented by Scottish comedian and actor Billy Connolly. It focuses on his travels along the famous United States highway, Route 66. The series, which consisted of four episodes, was shown on the British television network ITV. The first episode aired at 9pm on 15, 2011 .
Document 10: U.S. Route 66 in Arizona: U.S. Route 66 (US 66, Route 66) covered 401 mi as part of a former United States Numbered Highway in the state of Arizona. The highway ran from west to east, starting in Needles, California, through Kingman and Seligman to the New Mexico state line as part of the historic US 66 from Santa Monica, California, to Chicago, Illinois. The highway was decommissioned in 1985, although portions remain as State Route 66 (SR 66).
Document 11: U.S. Route 380: U.S. Route 380 is an east–west United States highway. The highway's eastern terminus is in Greenville, Texas at an intersection with Interstate 30, of which the easternmost 3–4 miles are concurrent with US 69 in a loop around the west and south sides of Greenville. Its western terminus is at San Antonio, New Mexico, south of Socorro at an intersection with Interstate 25. It intersected with its parent, U.S. Route 80, at Cisco up to 1971, when it was rerouted along the former SH 24 from that highway's western terminus near Old Glory to Greenville . Former U.S. Route 380 from Cisco to near Old Glory became an extension of SH 6. The highway no longer connects to any x80 route. US 380 passes through some of the far northern suburbs of the Dallas/Fort Worth Metroplex, including Denton, Frisco, and McKinney. The portion in Texas from the New Mexico Border to Jayton was SH 84 before 1939. Its spur, SH 84A, went from Jayton to Aspermont, until 1930, when it became SH 161.
Document 12: U.S. Route 138: U.S. Route 138, commissioned in 1926, is an east–west U.S. Highway in Colorado and Nebraska that runs predominantly northeast to southwest paralleling the South Platte River and Interstate 76. Like all spurs of the former U.S. Route 66 and U.S. Route 99, U.S. Route 138 is an orphan route. U.S. Route 38 was commissioned in 1926, but U.S. Route 6 was extended over it to Long Beach, California (but was truncated to Bishop in 1964). Therefore, U.S. 138 still meets its former parent route.
Document 13: U.S. Route 66 in California: U.S. Route 66 (US 66, Route 66) is a part of a former United States Numbered Highway in the state of California that ran from the west in Santa Monica on the Pacific Ocean through Los Angeles and San Bernardino to Needles at the Arizona state line. It was truncated during the 1964 renumbering and its signage removed in 1974. The highway is now mostly replaced with several streets in Los Angeles, State Route 66 (SR 66), Interstate 15 (I-15) and I-40.
Document 14: U.S. Route 66: U.S. Route 66 (US 66 or Route 66), also known as the Will Rogers Highway, the Main Street of America or the Mother Road, was one of the original highways within the U.S. Highway System. US 66 was established on November 11, 1926, with road signs erected the following year. The highway, which became one of the most famous roads in the United States, originally ran from Chicago, Illinois, through Missouri, Kansas, Oklahoma, Texas, New Mexico, and Arizona before ending at Santa Monica, California, covering a total of 2448 mi . It was recognized in popular culture by both the hit song "(Get Your Kicks on) Route 66" and the "Route 66" television show in the 1960s.
Document 15: Missouri Route 76: Route 76 is a highway in the west half of southern Missouri running between U.S. Route 60 and U.S. Route 63 at Willow Springs and the Oklahoma state line near Tiff City where it continues as a county road. It is the most famous road in Branson where it is known as "76 Country Boulevard" and features many of the entertainment theaters for which Branson is famous. The road runs for its entirety through the Missouri Ozarks, and is at times very hilly and curvy.
