The 149th Street–Grand Concourse station is a New York City Subway station complex shared by the IRT Jerome Avenue Line and the IRT White Plains Road Line. It is located at East 149th Street and Grand Concourse in Mott Haven and Melrose in the Bronx. The complex is served by the 2 and 4 trains at all times, and by the 5 train at all times except late nights. History First subway Planning for a subway line in New York City dates to 1864. However, development of what would become the city's first subway line did not start until 1894, when the New York State Legislature authorized the Rapid Transit Act. The subway plans were drawn up by a team of engineers led by William Barclay Parsons, chief engineer of the Rapid Transit Commission. It called for a subway line from New York City Hall in lower Manhattan to the Upper West Side, where two branches would lead north into the Bronx. A plan was formally adopted in 1897, and legal challenges were resolved near the end of 1899. The Rapid Transit Construction Company, organized by John B. McDonald and funded by August Belmont Jr., signed the initial Contract 1 with the Rapid Transit Commission in February 1900, in which it would construct the subway and maintain a 50-year operating lease from the opening of the line. In 1901, the firm of Heins & LaFarge was hired to design the underground stations. Belmont incorporated the Interborough Rapid Transit Company (IRT) in April 1902 to operate the subway. The 149th Street–Mott Avenue station was constructed as part of the connection between the IRT's East Side Branch (now the Lenox Avenue Line) and the West Farms Branch (now the White Plains Road Line). This connection was constructed in two phases: section 9A, west of Gerard Avenue in the Bronx, and section 9B, east of Gerard Avenue. McMullen and McBean were hired to build section 9A on September 10, 1901, while J. C. Rodgers & Son were hired to build section 9B on June 13, 1901. The section 9 began at 135th Street and Lenox Avenue in Manhattan, ran under the Harlem River, and surfaced in the Bronx at Melrose Avenue. In the portions of this double track section not beneath the river, three types of construction (standard steel frame, reinforced concrete, and concrete arch) were used. Twin cast-iron tunnels were built under
