Constructed between 1875 and 1878, the 3rd Ave el ran from City Hall in Manhattan to the Harlem River. Through service between Manhattan and the Bronx began in 1896. This elevated line was the last elevated line to run in Manhattan with service to South Ferry ending in 1950 and City Hall in 1953. Northward, the 3rd Ave line had service from Chatham Square until 1955. However, service in the Bronx continued for a few years after operation ended in Manhattan. It ran between 149th Street and Gun Hill Road from 1955 to 1973. The line in the Bronx was completely demolished in 1977.
