Engineers move 1,100 foot, 6.8 million pound bridge… all in one piece [Video]

2013-01-22_004757

Let’s say you have a long, heavy bridge that is old and deteriorating in condition. This bridge is critical to the area. What do you do to fix the issue? This is the exact situation the engineers at Oregon’s Multnomah County faced. What did they decide? To move the bridge (Sellwood Bridge) and use a temporary detour bridge while a new bridge was being built.

So, this past Saturday engineers took roughly twelve hours to move the ‘truss span’ of the bridge a grand total of 68 feet north to make room for the temporary detour bridge. The bridge itself is 1,971 ft long but the truss span is 1,100 feet long and 6.8 million pounds. The miraculous part of the move is the truss span was moved all in one piece — it wasn’t broken apart first. Check it out:

    @Mike: My guess? Less laws, worst medical care, and a world filled with R2-D2 ;-)

    @Ashraf: Lawyers definitely are necessary. But think how much better the world would be, if more people by default became creators like engineers . . . .

    @KC4COP: Is that bad? I’m not an engineer LOL!
    @Mike: Some would argue so are lawyers. See what I’m saying? :-)

    @Ashraf: Unfortunately (and off-track), weapons sometimes still are necessary . . . .

  • A bridge truss span that is 1,100 feet long weighing only 6.8 million pounds?

    @Mike: How about the ones that does not-so-great things, such as weapons? Just sayin’ — hard to generalize.

    Aren’t engineers great and unsung folks? Forget the lawyers–give me an engineer any day.
