Baltimore Inner Harbor, Pier 6, South of Pratt Street between Concord Street & Jones Falls outlet, Baltimore, Independent City, MD

Significance: Designed by Oscar F. Lackey and constructed in 1908-1910, the bulkheads on Piers 4, 5, and 6 in the Baltimore Inner Harbor were among the first reinforced concrete structures erected in seawater in the United States. These and other early concrete piers in the U.S. pioneered the acceptance of reinforced concrete in American harbors. The solid piers, consisting of filled reinforced concrete bulkheads, played a significant role in the evolution from timber pile to reinforced concrete for seawater construction.
