Completed in 1940, this lock spans the rivernear Clarksville, Missouri, and consists ofonly one 600-ft lock for an average lift of 15feet. This lock was the first one constructedunder the 9-ft channel project without rollergates — a huge leap in lock and dam engi-neering at the time. It has 15 tainter gatesthat controls the flow of the mightyMississippi River.

Construction of Melvin Price Locks and Dam began in 1979 and was completed in1994. Old Locks and Dam 26 was removedbeginning in 1990 when the main lock atMelvin Price became operational. MelvinPrice Locks and Dam operates 2 lock cham-bers — a 600-ft lock and a 1200-ft lock foran average lift of 20-ft. Throughout its designand construction, the Corps of Engineersemployed state-of-the-art computer-assisteddesign, testing, and evaluation to create astructure that represents the very best in river navigation control works.

Completed in 1953 near Granite City, Illinois, the twin locks at Lock 27 aresituated at the southern end of an 8.4-mile long, man-made canal. This lastdownstream lock moves more cargo than any other navigation structure on the Mississippi River. After 1940, only a single obstacle prevented the safe and reliable operation of a 9-ft navigation channel — a 17-mile series of rock ledgesjust North of St. Louis knownas the Chain of Rocks Reach.The Corps of Engineers constructed the canal tobypass the treacherous Chainof Rocks Reach and then builta low-water dam across themain river channel to ensureadequate pool depths.

This lock and dam went into operation in1939 near Winfield, Missouri, and consists of one 600-ft lock for an average lift of 15feet. It was equipped with 3 submersible roller gates and 14 submersible tainter gates.At the time of construction, submersible gatesrepresented a marked improvement in thatthey allowed for the almost unobstructed flow of floodwaters, ice and debris.
