It began in 1913 and has ten contributing resources and seven noncontributing ones.","why_significant":"The district is significant under Criterion A for its role in maintaining and operating the Illinois Waterway's lock and dam facilities. The Corps founded the boatyard and marine ways in 1913 to service its fleet, and the facility was developed further in the 1920s and 1930s. Most of the historic fabric dates from improvements made in 1928 and 1931-32.","narrative":"Along the Illinois River in a light industrial part of Peoria, this Army Corps of Engineers complex has serviced the boats and barges that keep the waterway working since 1913. The district includes a marine ways, where metal flat cars on tracks haul vessels out of the water for dry-dock repairs, and a rectangular boat harbor cut into the shoreline. Floating equipment includes Derrick Boat No. 3, the work barge Atlas, and the push boat Pekin. Plain metal-sheathed buildings hold storage, carpentry, painting and vehicle space, and a long brick garage dates from the 1930s. Newer additions, such as a 1992 office building, are counted as noncontributing. The complex was listed for its part in the maritime, transportation and industrial history of the Illinois Waterway, supporting the lock and dam system. Most surviving historic fabric comes from improvements made in 1928 and 1931-32.","period_of_significance":"1913-52","architect_builder":"U.S. Army Corps of Engineers","architectural_style":"No style","criteria":["A"],"status_note":"Still used for water-related transportation.
