The IRT Third Avenue Line, commonly known as the Third Avenue Elevated, Third Avenue El, or Bronx El, was an elevated railway in Manhattan and the Bronx, New York City. Originally operated by the New York Elevated Railway, an independent railway company, it was acquired by the Interborough Rapid Transit Company (IRT) and eventually became part of the New York City Subway system.

Interborough Rapid Transit Company
The Interborough Rapid Transit Company (IRT) was the private operator of New York City's original underground subway line that opened in 1904, as well as earlier elevated railways and additional rapid transit lines in New York City. The IRT was purchased by the city in June 1940, along with the younger BMT and IND systems, to form the modern New York City Subway. The former IRT lines are now the A Division or IRT Division of the Subway.
