From 1930-1933, Route 66 followed North Cotton Hill road.  In 1933, Route 66 was moved to the current location of I-55 where it crosses Lake Springfield.

This 1930-1933 alignment was abandoned with the creation of Lake Springfield. The man-made lake was created by damming Sugar Creek, which covered 1,600-feet of the pavement.

This alignment of Route 66 comes out of the lake in a heavily wooded, private-owned area, and continues south from a private residential drive onto East Lake Shore drive, then onto Olde Carriage Way (also called the Glenarm Alignment).
