The Starved Rock Lock and Dam, also known as Lock and Dam No. 6, was constructed between 1926 and 1933 as a critical part of the Illinois Waterway project. This ambitious endeavor aimed to create a navigable channel connecting the Great Lakes to the Gulf of Mexico via the Mississippi River. Initially, a contractor failed to proceed in 1923, but after resolving land litigation issues, a second contract was awarded in 1926. The construction faced financial challenges from the State of Illinois, leading the federal government to step in and complete the project under the Rivers and Harbors Act of 1930. The total cost amounted to over $4.4 million, with both state and federal funds contributing. The lock itself is a standard "Panamax" size, 600 feet long by 110 feet wide, designed to raise or lower boats by 17 to 19 feet. Recognizing its significance in engineering, transportation, and maritime history, the Starved Rock Lock and Dam was officially listed on the National Register of Historic Places in 2004.
