The High Line was never intended to be a view corridor.
It rose in the 1930's from a need to get freight trains off of 10th Ave: they were killing too many people. It snaked its way up out of the Hudson Yards and down through the industrial neighborhoods of Manhattan's far West Side to its original terminus at Washington Street and Houston. Some buildings took advantage of this freight artery with second or third story sidings and spurs, while others were mutilated or demolished to make way for its mid-block cut.
For most of its existence the High Line was an eyesore. It engaged buildings that needed access to its trains, with the rest turning their backs on it. Traveling along it one would view blank façades, cluttered shafts and alleys between buildings, roofscapes, loading docks, and long axial views down Chelsea's numbered streets before it passed into the more opaque street matrix of the West Village. It was noisy, smokey, and dirty: not something to celebrate with glass walled luxury residences.
Of course today, that's what one increasingly sees. It has become a real estate goldmine despite the initial clamor of short sighted developers to raze it. Millions of yearly visitors have now replaced millions of tons of freight. Walking along it, they are still able to catch unexpected vistas that were never intended for consumption. This unusual and unintended perspective on the city is what makes the High Line something to be savored. However, its success has not only turned the opinions of its one time detractors, but also the façades of the buildings popping up along it.
No longer shunned with architectural nether regions, the High Line is now the featured neighborhood attraction. Floor to ceiling windows of multi-million dollar condos gaze upon it. Boutique artisanal vendors politely hawk their goods along it. The very hip Standard Hotel—beloved of exhibitionists for its glass walls—lewdly straddles it and the Whitney Museum moved from the tawny Upper East Side to now anchor it in the Meatpacking District.
The increasingly curated spectacle of the High Line's entourage is definitely entertaining and worth a look. However, I recommend visiting sooner rather than later, while one can still gawk at unintended glimpses of the nether regions of the neighborhood's vanishing industrial past.
