Swinging a bridge in Wuhan

[dnoblett]

Now THAT’S a swing bridge! Chinese engineers build 17,000-ton flyover section at 90 degrees so railway below could remain open… then rotate it into place

 

Engineers took 90 minutes to swivel the structure into place in Wuhan City Jan 15. The section was built separately so as not to disturb the busy high speed railway track beneath it. It was the first time the unusual construction technique was used in the country

China is home to the largest high speed rail network in the world.

 

Forward-thinking engineers in China are the first in the country to have built a section of an enormous overpass and rotate it into place upon completion so as not to disturb the railways below. A 17,000 ton part of an elevated motorway was slowly swung into place in Wuhan City after being constructed independently beside a high speed railway track.

That was one neat trick for sure. It is pretty amazing what engineers can accomplish sometimes.

 

On another aspect of the article, I guess I spent far too many years editing magazine and newspaper articles. In newspapers especially, wording has to be very concise and there are constant space issues. This segment of the article is poorly written, with the second paragraph repeating what was said in the first, but adding a few new facts. It's really no big deal and also none of my concern to be honest. But those kind of little things sometimes drive me nuts - writing for newspapers puts a premium on words and one has to be very economical in their use. It's like Hemingway, who cut his writing teeth as a reporter for the Kansas City Star. Hemingway was always a verbal tightwad when it came to writing. He was in many ways like the Joe Friday of literature: "Just the facts, Ma'am."

 

Sorry about that little digression. Dan, if you want to delete it, be my guest.

Here in Portland the Sellwood bridge was long overdue for a rebuild. Instead of building a whole new temporary bridge while they build a new one they simply built the temporary pilons and used Palmolive dish soap to slide the old bridge over onto the pilons. I guess there's something special about Palmolive that no other dish soap will do.
