New York (N.Y.). Borough of the Bronx.

In 1898 the Bronx, formerly a part of Westchester County, was incorporated into the City of New York along with the other four boroughs (all islands) comprising the City of New York and in 1914 the Borough also becomes the Bronx County. It is the only New York City borough on the mainland. In order to reducing navigation hazards on the Harlem River near Spuyten Duyvil, the river's course was straightened in 1895 and the Marble Hill area of Manhattan was separated from the island with the Marble Hill cut. This collection of 696 photographs records in detail the construction of the sewers and parkways in the Bronx during the formative years of the rapid expansion of the City of New York as a world city. Many still existing sites, streets, railroad lines, parks and bridges are recorded in this collection of construction photographs in the developmental stages of their construction.
