when was the first subway built in new york city
History of the New York City Subway The first underground line opened on October 27, 1904,[8] almost 35 years after the opening of the first elevated line in New York City, which became the IRT Ninth Avenue Line.[9] By the time the first subway opened, the lines had been consolidated into two privately owned systems, the Brooklyn Rapid Transit Company (BRT, later Brooklyn–Manhattan Transit Corporation, BMT) and the Interborough Rapid Transit Company (IRT). Many present lines were built under the Dual Contracts, and after 1913, all lines built for the IRT and most other lines built or improved for the BRT were built by the city and leased to the companies. The first line of the city-owned and operated Independent Subway System (IND) opened in 1932; this system was intended to compete with the private systems and allow some of the elevated railways to be torn down. However, it was kept within the core of the city because of the low amount of startup capital provided to the municipal Board of Transportation by the state.[10] This required it to be run "at cost", necessitating fares up to double the five-cent fare popular at the time.[11]
History of New York City During the 19th century, the city was transformed by immigration, a visionary development proposal called the Commissioners' Plan of 1811 which expanded the city street grid to encompass all of Manhattan, and the opening of the Erie Canal in 1825, which connected the Atlantic port to the vast agricultural markets of the Midwestern United States and Canada. By 1835, New York City had surpassed Philadelphia as the largest city in the United States. New York grew as an economic center, first as a result of Alexander Hamilton's policies and practices as the first Secretary of the Treasury.[27][28]
