One of the first large scale uses of concrete construction in the country, the Hennepin Canal linked the Illinois River with the Mississippi River. Along the 104.5 mile waterway, locks were constructed of concrete, unlike the Illinois and Michigan Canal's limestone block locks.
Lift bridges were located in a few places to provide a place for wheeled vehicles to cross the canal. This lift bridge on Lock 21 near Wyanet, Illinois still stands, and traffic is allowed to drive over.
The location of the Hennepin Canal is much more rural than most of the I and M Canal, so a walk along the towpath is very peaceful and scenic.
