Illinois Route 41

Illinois Route 41 is a north-south highway in rural west-central Illinois. It runs from near Macomb to Galesburg, a distance of roughly 38 miles (62 km).

This route parallels the CB&Q railroad from Galesburg to its southern terminus at U.S. Route 136. This route crosses over the CB&Q right-of-way (Galesburg to Beardstown) twice along its 38 mile distance.

IL-41 enters Galesburg from the south on Linwood Road. The historic alignment turned northeast on Monmouth Blvd. through an industrial section between the former Santa Fe mainline to the north and the former CB&Q connector to the south. At South Henderson Street, the historic route turned north, crossing the old Santa Fe mainline and terminating at West Main Street, cosigned as U.S. Route 150 and Illinois Route 164.

This alignment moved west with the completion of U.S. 34 as a 4-lane expressway to [[Monmouth]. IL-41 now proceeds north on an upgraded and wider Linwood Road to West Main Street Illinois Route 164 where it terminates at the nearby access interchange for U.S. 34.
