A massive archaeological site in St. Clair County, Illinois, was excavated by ISAS for the Illinois Department of Transportation between 1998 and 2007 to make way for a new bridge over the Mississippi River. ISAS archaeologists excavated some 7,000 discrete “features,” locations of trash-filled storage pits and houses, among other things, near the banks of the Mississippi River.
