UPDATE: The user, wishing to remain anonymous, removed the video telling BostInno directly, “Cannot comment on why it was taken down, I’m all for promoting civil engineering and I appreciate your interest in it.”

There’s no denying that the Leornard P. Zakim bridge adds a certain spirited flare to the Boston skyline. The Zakim, as it’s referred to simply by locals, with its signature dual-obelisk capstones and eight lane Expressway sprawling below, is a marvel of modern civil engineering. Standing 273 ft tall, the Zakim could give those with most audacious nerves a healthy does of vertigo just by standing nearby and looking up.

So could you imagine careening from the very tip to the very bottom?

A new video uploaded to YouTube depicts just that. Dated October 1, the footage is of an inspection of the Zakim shot via a helmet camera at 1 am showing exactly the kind of balance and grace reminiscent of an Olympic gymnast that goes into such examinations.

He begins by standing at the apex of the unofficially named “Bunker Hill Bridge” (because of its likeness to the Charlestown monument of the same name) as he proceeds to secure himself safely and propel down between the bridges cable-stayed legs in the light of the Zakim’s popular blue fluorescent lights.

Though hardly the tallest structure in Boston, standing at such heights would be enough to make anyone weak in the knees.
