Scope and Content Note

This series consists of approximately 1000 shop drawings, which were used in conjunction with individual Barge Canal contracts to produce detailed specifications. The maps are primarily on linen and contain a great level of detail; from these plans contractors and manufacturers were able to fulfill specific terms of contracts. Included are shop drawings for the components of bridges, locks, gates, dams, winch cars, and other canal mechanisms. Indexes to contract sheets are often included with contract shop drawings. Also included in this series are shop drawings for four maintenance contracts, 1982-1984. The drawings are arranged by contract number.
