Route description

Illinois 16 is a major eastwest state highway in Central Illinois. It runs east from Hardin to Hillsboro, and then turns northeast to Pana. Illinois 16 then continues east to Shelbyville and then to Paris. It overlaps Illinois 133 shortly before entering Paris.

In Paris, Illinois 16 and Illinois 133 terminate at the intersection of Jasper and Main/Central Streets. Illinois 16/133 run west from this intersection, while U.S. 150 runs north and east. Illinois 1 runs north and south.


SBI Route 16 was established in 1918, running originally from Litchfield east to Paris. In 1962, a new 4-lane highway was built from Mattoon to Charleston; this became Illinois 16, while the old alignment became Illinois Route 316, which was dropped sometime in the 1970s.[2]
