Is this really the shortest street in Manhattan?

Manhattan has no shortage of dead-end alleys and one-block streets.

But at 63 feet long, Edgar Street, way down beside Battery Park City off of Greenwich Street, just might hold the title of the borough’s shortest thoroughfare.

It’s named after a shipping magnate whose mansion fronted Greenwich Street around the turn of the 19th century, when lower Greenwich was the Millionaire’s Row of the era.

Edgar Street’s title come from an insightful post from the folks at Curbed, who relied on data from Property Shark. The Street Book, which explains the origins of all of Manhattan’s street names, also cites Edgar Street as the shortest.

Thing is, other sources have it that Mill Lane should get shortest-street honors.

“[T]iny Mill Lane in the financial district appears to be the shortest of them all, coming in a few feet shorter than Edgar Street,” stated Michele and James Nevius, authors of Inside the Apple, in a New York Times Q and A.

Over in the West Village, an ancient sign nailed to a wall on slender Weehawken Street names this one-block lane between West 10th and Christopher Streets as Manhattan’s smallest (above left).

Gay Street, Moore Street, Jones Street, and St. John’s Lane are also contenders for the title.

So which is really the shortest street?

Since Mill Lane doesn’t appear to allow traffic through it anymore, I’m going with Edgar (right, in an undated NYPL photo . . . is that the Ninth Avenue El overhead?).
