Most Midtown cross streets run in a long, straight line across the island, a product of the 1811 grid plan that gave Manhattan its famous numbered order. East 41st Street is a quiet exception. Near where it meets Madison Avenue, a block south of Grand Central and a block from Fifth Avenue, it behaves like any other mid-block corridor of office entrances and loading docks. But follow it west and it ends at Fifth Avenue, opposite the New York Public Library: between Fifth and Sixth Avenues there is no 41st Street at all. (At its eastern end it stops short too, at Tudor City Place rather than First Avenue.) The western interruption is not an accident of modern planning; it is the residue of what stood on this ground more than a century ago, and it gives this otherwise unassuming street a genuinely distinctive history.
A reservoir where a street should run
From 1842 until 1899, the Fifth Avenue side of the block between 40th and 42nd Streets was occupied by the Croton Distributing Reservoir, a massive, Egyptian-revival-style water-holding structure built as part of New York's then-new Croton Aqueduct system; it opened to a crowd of some 20,000 people on July 4, 1842. The reservoir was a civic landmark in its own right, with sloped granite walls that New Yorkers reportedly climbed for promenade views over a city still mostly low-rise. Behind it, on the rest of the block toward Sixth Avenue, lay a public square, opened in 1847 as Reservoir Square and renamed Bryant Park in 1884. With the whole block given over to the reservoir and the square, the stretch of 41st Street that the grid plan had mapped between Fifth and Sixth Avenues was never opened as a through street — it existed on paper, not on the ground.
The library takes the block
The reservoir was demolished in 1899 to make way for a new central library building, and the Main Branch of the New York Public Library — today known as the Stephen A. Schwarzman Building — opened on the same site in 1911. The library, like the reservoir before it, spans the full block from 40th to 42nd Street along Fifth Avenue, with Bryant Park occupying the rest of the block behind it toward Sixth Avenue. The practical result is that 41st Street still does not pass between Fifth and Sixth Avenues; the grid interruption begun by the reservoir and its square was simply inherited, and then made permanent, by the library and park that replaced them.
Grand Central's gravity
East of Fifth Avenue, where the street does run continuously past Madison and Park Avenues, its character was shaped less by what sat directly on it and more by what rose a block north. Grand Central Terminal opened in February 1913, replacing the earlier Grand Central Station on the same site — itself a 1900 rebuilding of the original Grand Central Depot of 1871 — and its construction, along with the burial of rail approach tracks that made the modern Park Avenue possible, triggered a wave of office and hotel building around it in the 1910s and 1920s, concentrated in the planned "Terminal City" north of 42nd Street. Vanderbilt Avenue, a short street running north from 42nd Street alongside the terminal, takes its name from the family behind the New York Central Railroad and the terminal itself. The area immediately to the south, Murray Hill, had by the mid-to-late 19th century become known across the wider neighbourhood as a residential enclave for some of the city's wealthier families; that reputation belongs to Murray Hill more broadly rather than to this particular block, but it is part of the surrounding fabric that East 41st Street sits within and that shaped the commercial redevelopment that eventually reached it.
What's left on the ground today
Today the open, east-of-Fifth stretch of East 41st Street reads as a fairly typical Midtown corridor: mid-rise and high-rise office buildings, service entrances, and pass-through pedestrian traffic heading for Grand Central or the library steps. Two blocks south, on East 39th Street just off Fifth Avenue, the Fifth Avenue Tower urban plaza is one of the many privately owned public spaces that became common across Midtown after the city's 1961 zoning resolution began offering developers extra floor area in exchange for ground-level space open to the public; this one was built with the residential tower in the mid-1980s, under the revised "urban plaza" standards the city adopted in 1975. The block's present-day identity — dense, corporate, pedestrian-through rather than pedestrian-destination — is a late layer over a much odder history underneath it.
Its real story is one of absence and adjacency: a segment of grid left unopened by a reservoir and its square, inherited by a library and park, and, on the side that did get built, pulled into shape by the enormous gravitational pull of a railroad terminal a block away.
