^Northbound trailblazer leaving the US Route 150 interchange. July 2016.
Though the route numbered "6" encountered the most in Illinois is US Route 6, Illinois also has a state route numbered "6" in the Peoria area. Illinois Route 6 runs circumferentially around the northwest side of Peoria, serving as a northern extension of Interstate 474. It is a freeway for its entire length, except for the future trumpet spur directing all traffic to Illinois 29 at the northern end.
