IRT Lexington Avenue Line

IRT Lexington Avenue Line is a major rapid transit line of the New York City Subway, forming the backbone of transit on the East Side of Manhattan. Operated by the New York City Transit Authority, it is one of the busiest subway lines in the United States, serving the <4>, <5>, <6>, and <6> services. The line runs from 125th Street in East Harlem south to South Ferry in the Financial District.

History

The line was constructed as part of the first subway, developed by the Interborough Rapid Transit Company (IRT) and opened in stages between 1904 and 1908. Its construction followed the route of the former Lexington Avenue surface corridor and was a monumental engineering project overseen by William Barclay Parsons. Key early extensions included the 1905 opening of the Joralemon Street Tunnel to Brooklyn, connecting to the IRT Eastern Parkway Line. The line was later integrated into the city-owned Independent (IND) and BMT networks following the 1940 unification. Major mid-century projects included the 1956 connection to the IRT Pelham Line and the 1967 opening of the Chrystie Street Connection, which integrated services with the BMT Nassau Street Line.

Service

The line provides 24/7 service and is the primary north-south artery on Manhattan's East Side, carrying the <4>, <5>, and <6> trains. The <4> and <5> trains run express on the four-track segment between 125th Street and Grand Central–42nd Street, while the <6> train runs local, with the <6> providing peak-direction express service in the Bronx. These services connect to numerous other lines, including the IRT Flushing Line at Grand Central and the IRT Broadway–Seventh Avenue Line at Brooklyn Bridge–City Hall. The line interfaces with major transportation hubs like Grand Central Terminal and connects to the Staten Island Ferry at its southern terminus.
