Route 366 is a highway located completely within the St. Louis metropolitan area. It is primarily a former section of U.S. Route 66. Beginning at South Broadway/South Jefferson Avenue in St. Louis and ending at the Interstate 44/Interstate 270 interchange in Sunset Hills, it was established in 1979 when US 66 was decertified between Chicago, Illinois and Joplin, Missouri.
Through the several suburbs of St. Louis it is known as Watson Road, while in the city of St. Louis itself, it is named Chippewa Street.
