"Real estate speculators, shippers, and business interests could not agree on the best way to utilize the Harlem, (river) debating whether public works should facilitate traffic across the river or shipping along the river. Coastal trade interests advocated for a Harlem River Canal, but their opponents argued that transportation across the river was more important. This map of the river between the Hudson River (top) and the East River (bottom) accompanied an unsuccessful proposal to have the state legislature turn the Harlem into a subterranean river and connect Manhattan with the mainland between Third and Eighth Avenues (section shaded red)."
