1. Illinois and Mississippi Canal Marker
Inscription. Construction on the “Hennepin Canal,” as it was commonly known, began in 1892 and was completed in 1907 at a cost of more than seven million dollars. The main canal extended 75 miles from the Illinois River near Hennepin to the Rock River near its juncture with the Mississippi. A feeder canal from the Rock River at Rock Falls joined the main canal 29 miles to the south near Mineral. Utilization of the Hennepin Canal never reached expected proportions because of rapid technological advances in other modes of transportation, and in 1951 it was closed to traffic.
 
Erected 1974 by Sterling-Rock Falls Historical Society and The Illinois State Historical Society.
