Why you should experience the IRT Jerome Avenue Line in New York, NY.
The IRT Jerome Avenue Line is a storied rapid transit corridor where the Bronx's transportation history, engineering ambition, and neighborhood identity converge across one of New York City's defining subway routes.
Extending from Mott Haven through Highbridge, Mount Eden, University Heights, Fordham, Bedford Park, and Woodlawn, the line follows Jerome Avenue for much of its journey while connecting residential districts, commercial corridors, educational institutions, and civic destinations. Elevated steel structures, masonry station houses, riveted viaducts, and underground approaches demonstrate successive phases of early twentieth-century subway construction. Riding the IRT Jerome Avenue Line reveals how transportation infrastructure shaped the western Bronx while continuing to serve the neighborhoods that developed around it. The result is a corridor that remains fundamental to the borough's physical and historical development.
What you should know about IRT Jerome Avenue Line.
The IRT Jerome Avenue Line is best known for being authorized under the Dual Contracts of 1913, with service opening in successive phases during 1917 and 1918 as the Interborough Rapid Transit Company expanded rapid transit into the western Bronx. The route comprises 14 stations extending between 138th Street-Grand Concourse and Woodlawn, while the 4 train operates over the full length of the line and the 5 train provides service to its southern terminal during designated operating periods. South of 161st Street-Yankee Stadium, the alignment emerges from the Grand Concourse subway tunnel onto an elevated steel structure before continuing north above Jerome Avenue. Three-track construction, express operating flexibility, and direct access to Jerome Yard established the line as both a major passenger corridor and an essential operating component of New York City's subway network.
Built across the steep terrain of the western Bronx, the elevated structure employs riveted steel girders, lattice columns, and long-span framing that enabled rapid transit to follow Jerome Avenue without extensive alteration to the existing street network. Surviving infrastructure inherited from the former IRT Ninth Avenue Elevated south of 167th Street demonstrates how earlier elevated railway construction influenced expansion of the city's developing subway system. Daily fleet storage, inspection, dispatching, and maintenance activities centered at Jerome Yard continue supporting reliable operation of the route while reinforcing its long-standing operational importance. Together these engineering systems, inherited structural elements, and railroad facilities demonstrate how the IRT Jerome Avenue Line has remained one of the Bronx's most significant pieces of transportation infrastructure for more than a century.
