McAlpine Locks and Dam is located in downtown Louisville, Kentucky. The dam is at mile 604.4 of the Ohio River and the locks are in the Louisville and Portland Canal on the Kentucky side of the river. The 56’ x 600’ auxiliary lock was completed in 1921 and the 110’ x 1200’ main chamber was opened in 1961. There is also an inactive 56’ x 360’ lock chamber. In 1960, the project was renamed from Lock and Dam 41 in honor of a former Louisville District Engineer. Construction began at McAlpine in 1996 on a new 110’ x 1200’ lock, which will replace the active 110’ x 600’ auxiliary and an inactive auxiliary lock. Innovations associated with this project include roller compacted concrete walls, wrap around filling and emptying system with in-chamber culverts, a shortened guide wall and reduced cofferdam length. Construction began in 1996 and is scheduled for completion in 2009, dependent upon funding.
During construction, the McAlpine project is reduced to a single chamber project because the new 1200’ lock is being constructed in the foot-print of the auxiliary 600’ chamber.
