Question: Which city in Missouri is the Route 66 State Park closest to travel from, St.Louis or Eureka?

Context:
Casa Grande Hotel (Elk City, Oklahoma)
The Casa Grande Hotel is a historic hotel located at the intersection of 3rd Street and historic U.S. Route 66 in downtown Elk City, Oklahoma.
 The hotel opened in 1928, shortly after Route 66 was designated, to lodge the growing number of travelers on the highway.
 Architects Hawk and Parr designed the four-story building in the Spanish Eclectic style; their design features arched windows and doors and stone ornamentation along the arches.
 Spanish-influenced styles such as the Spanish Eclectic were common on the southwestern portion of Route 66 due to the region's Spanish history.
 The luxury hotel faded in popularity after the 1920s, and as a result, the Casa Grande is the only high-rise hotel on Route 66 between Oklahoma City and Amarillo, Texas.
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.
Angel Delgadillo
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 in Kansas
U.S. Route 66 (US 66, Route 66), the historic east–west US highway between Chicago, Illinois and Santa Monica, California, passed through one brief segment in the southeastern corner of Kansas.
 It entered the state south of Baxter Springs and continued north until it crossed the Brush Creek, from where it turned east and left the state in Galena.
 After the decertification of the highway in 1985, this road segment was numbered as US-69 (alternate) from Quapaw, Oklahoma north to Riverton, Kansas and as K-66 (Kansas highway) from Riverton east to Route 66 in Missouri.
Dixie Travel Plaza
The Dixie Travel Plaza, previously known as the Dixie Truck Stop and Dixie Trucker's Home, is a large trucker and travel plaza located in McLean, Illinois, on Interstate 55.
 It was established by J.P. Walters and John Geske in 1928 on old US Route 66 as a small sandwich stand in a truck mechanic's garage.
 By 1930, quickly growing demand had necessitated expansion into a full-size restaurant.
 The restaurant was expanded several times afterwards, and rebuilt once after a fire in 1965.
 Walters, Geske and the Dixie Trucker's Home have been recognized by the Route 66 Association of Illinois for their contributions—from 1926 to 1977—to the character of Route 66.
 They were inducted into the association's hall of fame on June 9, 1990.
 Dixie was previously home to the Route 66 Hall of Fame when it opened in 1990.
 In 2003, after Dixie changed ownership, the museum was moved to a new, larger location in Pontiac, Illinois.
Times Beach, Missouri
Times Beach is a ghost town in St. Louis County, Missouri, United States, 17 mi southwest of St. Louis and 2 mi east of Eureka.
 Once home to more than two thousand people, the town was completely evacuated early in 1983 due to a dioxin contamination that made national headlines.
 It was the largest civilian exposure to dioxin in the country's history.
Route 66 State Park
Route 66 State Park is a state park in the U.S. state of Missouri, located on the former site of the town of Times Beach.
 It is a 419 acre park located less than 1 mi east of Eureka.
Route 66 Park
Route 66 Mural Park (opened 2013 in Joplin, Missouri) operates as a public park, specifically as a touchstone for US Route 66 tourists as well as for local preservers of U.S. Route 66 in Missouri.
 The park includes two large tile murals proposed by Paul Whitehill, produced by Images In Tile USA and designed by artists Chris Auckerman and Jon White.
 The park also features a bifurcated red sports car that anyone on pilgrimage can slide up beside and have a quickie photograph taken.
 Close to the intersection of 7th Street and Main, the mural covers the south side of Pearl Brothers, the iconic green hardware store of downtown Joplin.
 Near that same intersection, US Route 66 once shifted west and headed into Kansas.
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.

West Tyson County Park is a county park in the U.S. state of Missouri consisting of 673 acres located in St. Louis County east of the town of Eureka.
