Paris Springs Junction is a small unincorporated community in Lawrence County, Missouri, United States.
 It lies along former U.S. Route 66 (now a county road west of the junction of Route 266 and Route 96), four miles (6 km) west of Halltown.
 Paris Springs Junction started as a few business on Route 66 and, with the decommissioning of that highway, has now become only homes.
 It was so named because of a former town named Paris Springs to the north.
 That town was founded in 1855 and survived until the time of Route 66's decommissioning.
Angel Delgadillo is a businessowner in Seligman, Arizona who has been dubbed the 'guardian angel' of U.S. Route 66.
 He is the main founder of the Historic Route 66 Association of Arizona, established in 1987 to campaign for "Historic Route 66" signage on the former US highway; similar initiatives have since been established in every U.S. Route 66 state.
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).
Shea's Gas Station Museum Center piece The Mahan Filling Station located on Route 66 in Springfield, Illinois was transformed from a working Texaco, and later Marathon, station into a world-renowned museum by owner Bill Shea and his wife Helen.
 The museum contains an eclectic mix of vintage gas station memorabilia collected over the last fifty years including the original gas pumps, wooden phone booths, signs, photos, and other mementos reminiscent of old Route 66 service stations.
 In February 2000, the former Mahan's Station, rumored to be the oldest filling station in Illinois, was moved 21 miles to its current location at Fulgenzi's.
 It has since been fully restored.
 The museum’s guestbook boasts visitors from all over Europe and Asia and has become a destination for international travelers exploring the Mother Road.
 Due to his commitment to preserving Route 66 history and gas station memorabilia, plus his many years of quality service to his customers, Bill Shea and his shop were inducted into the Route 66 Hall of Fame in 1993.
 The entire Shea family was inducted in 2002.
 Bill Shea died in December 2013 and the gas station was sold.
 The museum contents were auctioned in 2015.
 The Fulgenzi Family Saved the Museums Center piece, The Mahan Filling Station and its now open to the Public at Fulgenzi's Pizza & Pasta 1168 Sangamon Avenue, Springfield, Illinois 62702 .
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.

 In 1914, the road was designated "National Old Trails Highway" but in 1926 was re-designated as U.S. Route 66.
 In 1985, U.S. Route 66 was dropped from the highway system.
 Parts of the highway were either absorbed into I-40, turned over to the state (SR 66), or turned over to Yavapai County.
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.
