The road continues, as various county routes, eastbound beyond Illinois 37 to Allendale at Illinois Route 1. To locals, this part of the highway is known as "The Extension", referring to the fact that road "Extends" on after its official end.
Illinois 161 runs along portions of what once was U.S. Route 50 west of Scott Air Force Base. East of Belleville, it becomes a rural, two-lane surface road. Inside the Centralia city limits, Illinois 161 is coupled into eastbound Noleman Street and westbound McCord Street.
SBI Route 161 originally ran from Belleville to Carlyle; in 1941 it was rerouted from Carlyle to IL 37 at its current eastern end, replacing IL 182. In 1964 it was extended west to Fairview Heights.
