For the most part, Illinois Route 66 glides evenly and easily through the State in a diagonal direction between Chicago and St. Louis. Generally, it follows I-55, but, there are several alignments that zig-zag over, under, and parallel the interstate.
In the Land of Lincoln, the path begins near the shore of Lake Michigan. Connecting the Midwest with the golden state of California, the road from Chicago originally followed State Route 4 from Chicago to East St. Louis. This original piece of gravel road was built before Route 66 even existed and was first called the Pontiac Trail in 1915.
Enjoy your journey through the Land of Lincoln.
