Until 2007, only Route W appeared on this exit sign on US 67 in Farmington. Then, Missouri 221 was designated between Pilot Knob and Farmington, providing a direct route between central Iron County and Farmington. In St. Francois County, the Missouri 221 designation replaced Route W until the interchange with US 67. The highway continues as Route W into central Farmington.
