^This sign is supposed to say "North Illinois 148/East Illinois 154", but it's wrong. Still, this counts as a scene looking down Illinois 154 in Sesser, September 2021.
Illinois 154 is a somewhat significant east-west route in the western half of southern Illinois. It runs west from the Interstate 57 corridor which bisects the southern part of the state, through areas south of Mount Vernon and Saint Louis, but north of Marion and Carbondale.
