In the opening decades of the 20th Century, the proliferation of new subway lines in Brooklyn changed the shape of Brooklyn's busiest intersections; new routes were excavated and transit hubs born, replacing the streetcars and elevated railways of years past. This collection includes a selection of photographs documenting subway construction in and around Times Plaza, Flatbush Avenue, and Ashland Place.

Survey photograph of Bridge and Fulton Streets, June 10, 1907. The Hoyt Street-Bridge Street stop on the IRT Eastern Parkway Line (2/3 trains) is beneath this intersection, with two entrances presently located at the photographer’s vantage point and the site of excavations pictured. The sign reads “The care of this street is not within the jurisdiction of the Borough President. All complaints should be lodged with the Board of Rapid Transit Commission.”
