Aaaand… it’s gone

Old Kosciuszko Bridge, born 1939, died 2017

This was the old Kosciuszko Bridge, connecting Brooklyn and Queens. (The first span of its replacement was opened this past spring.) By the time you read this, all that remains will be a whole lot of rubble.

At noon yesterday, this announcement was made:

Tomorrow, 10/1, the NYS Department of Transportation will conduct an implosion of the old Kosciuszko Bridge between Brooklyn and Queens. The work will involve the use of explosives and will consist of warning sirens followed by a loud explosion at approximately 8:00 AM.

Motorists and pedestrians should expect traffic disruptions in the immediate area surrounding the bridge beginning tonight at approximately 10:00 PM. In addition, traffic on the Brooklyn Queens Expressway over the new Kosciuszko Bridge will be temporarily stopped in both directions shortly before and after the implosion. Please use alternate routes on Sunday, 10/1 if possible.

How it will be done:

It will be demolished using a process called energetic felling, which requires the placement of little charges at key joints on the bridge so that when the charges go off, the bridge breaks apart and falls directly down. The pieces will then be dismantled and removed.

About 22 million pounds of steel from the demolition will be recycled as scrap metal, according to [Governor] Cuomo’s office.

The old bridge, opened in 1939, was designed for 10,000 vehicles a day. When it closed this past April, it was somehow carrying 180,000.

    I knew it’s gotta happen one day! See a Polish commentator @ Kevin Walsh’s thread: “Anti-Pole-ites!” Ah, dears, how you suffer

    God bless those engineers who decided to overdo everything so that a bridge could somehow handle 18 times its expected workload without crumbling sans helpful demolition charges.

    The video of the implosion went by my Twitter feed a few days ago; I wish I could find it now to post for y’all. It was neat. Part of me is going to miss the old warhorse. (Incidentally, also named for an old warhorse and hero of several nations, including our own during its birth.)
