manhattan_bridge A recent timelapse video captures how the Manhattan Bridge sways up and down with each passing subway train. Thankfully though, the motion of the East River crossing isn’t nearly as drastic as the original Tacoma Narrows Bridge, which spectacularly collapsed months after its 1940 opening over the Puget Sound. See the Manhattan Bridge move, after the jump.
