125th Street, co-named Martin Luther King Jr. Boulevard, is a two-way street that runs east–west in the New York City borough of Manhattan, from First Avenue on the east to Marginal Street, a service road for the Henry Hudson Parkway along the Hudson River in the west. It is often considered to be the "Main Street" of Harlem. Notable buildings along 125th Street include the Apollo Theater, the Adam Clayton Powell Jr. State Office Building, the Hotel Theresa, the Studio Museum in Harlem, the Mount Morris Bank Building, Harlem Commonwealth Council, the Harlem Children's Zone, the Church of St. Joseph of the Holy Family, and the former West End Theatre, now home to the La Gree Baptist Church. History The street was designated by the Commissioners' Plan of 1811 that established the Manhattan street grid as one of 15 east–west streets that would be in width (while other streets were designated as in width). Neighborhoods The western part of the street runs diagonally between the neighborhoods of Manhattanville and Morningside Heights from the northwest from the West Harlem Piers and an interchange with the Henry Hudson Parkway at 130th Street. East of Morningside Avenue it runs east–west through central Harlem to Second Avenue, where a ramp connects it to the Robert F. Kennedy (Triborough) Bridge. However, 125th Street continues to First Avenue, where it connects to the southbound FDR Drive and the Willis Avenue Bridge. West of Convent Avenue, 125th Street was rerouted onto what was, prior to 1920, called Manhattan Street. What remains of the original alignment of 125th Street was renamed La Salle Street at that time. The remaining blocks run between Amsterdam Avenue and Claremont Avenue. The New York Times lamented the name changes, noting that the new names had "somewhat doubtful nomenclature", and that the City's "Aldermen like French names" but gave no rationale for the moves otherwise. A block of the original 125th Street in this area was de-mapped to make the super-blocks where the Grant Houses projects now exist. A proposal to convert the street into a Trans-Harlem Expressway died when funds were diverted from the proposed 125th Street Hudson River bridge at the street's western end. Beginning in the late 1990s, many sections of 125th Street have been gentrified and developed with such stores as MAC Cosmetics, Old Navy, H&M, CVS/pharmacy, and Magic Johnson Theaters.
