The Missouri Legislature voted to name the highway section the "Rosa Parks Highway"

In 1994 the Ku Klux Klan applied to sponsor a portion of United States Interstate 55 in St. Louis County and Jefferson County, Missouri, near St. Louis, for cleanup (which allowed them to have signs stating that this section of highway was maintained by the organization). Since the state could not refuse the KKK's sponsorship, the Missouri legislature voted to name the highway section the "Rosa Parks Highway". When asked how she felt about this honor, she is reported to have commented, "It is always nice to be thought of."
