Often overlooked and certainly overshadowed by its more famous neighbor, the Manhattan Bridge will, this December, become a centenarian. Quite a feat, all told, as the bridge’s history has been full of issues to say the least.
Gustov Lindenthal’s first design was thrown out purely for reasons of aesthetics. He came back with another idea – incorporating two thin-profile steel towers. This idea was retained but his main plan – four cables made of immense chains of eye bars (lengths of steel at least ten foot long joined at each end by steel pins) was again rejected. Perhaps the thought of what was essentially a gargantuan bicycle chain put the chills up the spine of the city fathers.

A time-lapse video of the Manhattan Bridge in New York City shows the how the bridge bounces as traffic flows over it.
WPIX News asked the NY Department of Transportation what’s up with the wiggles, and got this response:
"The bridge has moved this way for the last 100 years – exactly the way it was designed to – and it can move up to 16 inches daily with normal traffic conditions. The long-span suspension bridge flexibility by design allows the bridge to manage the weight of the traffic and subway cars it carries and the temperature shifts that occur throughout the year."
The Manhattan Bridge spans the East River from Lower Manhattan to Brooklyn. It opened in December, 1909, and has been renovated during the past 20 years.
You may have seen the bridge in such films as "Ghostbusters," and "Independence Day," and "I Am Legend."
