John Carr opened the Coral Court Motel in 1942, during the US World War II mobilization effort. The original twenty-room motor court consisted of one main office building plus ten individual buildings with two units each. Built in the streamline moderne style with a minimalistglass brick and ceramic tile face, a garage for each unit occupied the center of the buildings. In 1946, 23 more two-unit cabins were added, bringing the site to 66 rooms; three two-story buildings were added near the back of the property in 1953 and a swimming pool installed in the 1960s. The 1953 arrest of Carl Austin Hall, who briefly checked into the Coral Court on October 6, 1953 after fleeing Kansas City in the aftermath of the Bobby Greenleaseabduction and murder, brought notoriety; while he and an accomplice were sentenced to death, only half of the $600000 ransom was ever recovered. The ability to rent a room for short periods of time in complete discretion, with motorcars hidden from the street by the individual enclosed indoor garages, enhanced the Coral Court's notoriety as a popular venue for adultery. U.S. Route 66 was the main road in the area until bypassed by Interstate 44 in Missouri at the end of 1972 and business during this era was brisk. The loss of traffic to freeway construction would lead to an overall decline for many US 66 independent businesses, but the Coral Court appears to have been maintained in good condition until John Carr's demise in 1984. While Carr's widow would remarry, take ownership of the property and continue to operate the motel for several years, the buildings were allowed to decline severely. By 1988, the site was identified as at risk of loss to demolition as she had twice sold options on the land to prospective developers for a shopping mall. Local preservationists established the Coral Court Preservation Society and were successful in listing the property on the National Register of Historic Places, but this listing provides no protection to a site. The motel, in very poor condition after years of neglect, ultimately closed in 1993 and was demolished in 1995. Its site now contains a 45-unit housing development, called "Oak Knoll Manor." One of the two-unit buildings from the original motor court was carefully dismantled by volunteers for use as part of an automotive exhibit at the National Museum of Transportation in St. Louis. Constructed in 2000, it includes a 1941 Cadillac and the façade of one original art deco motel cabin building as part of a larger exhibit on automobiles of the era. While nothing else remains at the site, attempts have been made at the local level to advocate the installation of a historic marker or signage to indicate where the motor court once stood.
