History
A road connecting Marion to New Burnside was first marked on Illinois highway maps in 1922. Route 166 was designated along its current route in 1924 as a paved road 9 feet (2.7 m) wide connecting New Burnside and Creal Springs. The route was first marked between Route 13 and Creal Springs on the 1929 state highway map; at this point, it had not been paved. By 1931, Route 166 was completed to New Burnside and paved between Route 13 and Caneyville, a community north of Creal Springs. The 1931 map marked the route as Illinois Route 156 in error. The remainder of the route was paved by 1934.Major intersections
