Hennepin Canal Parkway State Park
Hennepin Canal Parkway State Park, Historic canal and state park in northwest Illinois, United States.
The Hennepin Canal extends 75.2 miles through five counties, featuring 33 locks and connecting the Mississippi River at Rock Island to the Illinois River.
Construction of the canal began in 1890 and concluded in 1907, marking the first American canal constructed entirely from concrete without stone cut facings.
The canal system represents early 20th-century engineering achievements, with its innovative Marshall gates operating similarly to mailbox mechanisms at several locks.
Visitors can access 155 miles of trails for hiking and biking, while designated areas allow horseback riding, fishing, camping, and non-motorized boating activities.
Six original aqueducts remain along the waterway, enabling the canal to cross rivers and streams through elevated water bridges.
