On April 27, 1837, an act was passed in the State Legislature to widen Fourth Avenue between 32nd Street and the Harlem River to provide room for the railroad. The street was widened by on either side, making the street wide. The company ceded the title for the land that would be occupied by Fourth Avenue to the city in exchange for permission to occupy it. In that same year, the railroad purchased six city lots at Fourth Avenue and 26th Street for $7,000 for the construction of car barns and stables. A tunnel stretching was completed through Prospect Hill, one of the highest points on the East Side of Manhattan, between modern 92nd Street and 95th Street, in 1837. The New York City Landmarks Preservation Commission claims that this is the oldest railroad tunnel in the United States.
