…and I have no clue how they do it with any kind of accuracy!

The Chinese are constructing the world’s largest highest bridge called the Siduhe Grand Bridge. This bridge is over 2,100 ft. tall, which makes it higher than any skyscraper in the United States by about 360 ft. This bridge is not only tall, but it is also about 3/4 of a mile long, making the combination of construction over a valley with that long of a span creating some really interesting contructability issues.

Well, China has their solution…use rockets to launch the suspension cables across the valley to construct the main supports. Instead of normal methods such as helicopters, they actually launched the cable across. The weight of those cables alone had to make the rockets fly awkwardly, but they have successfully launched them.

Check out the pictures below to see their method!

…when it starts to make speed bumps like the ones in China.

So, awhile back, I saw a new program that was started in Philadelphia to slow down cars without creating speed bumps called…and prepare to groan over this one…”Drive CarePhilly”. This lovely concept that was instituted in over 100 intersections involved using 3D decals on the ground to fake out drivers to thinking there was a speed bump there. Even if it worked for the first time, I would hope that humans are smart enough to tell next time that there really is no speed bump.

So China has decided to up the ante and show how they slow down travellers. I have to give them this, it definitely will slow down cars, no ifs ands or buts. They have placed a 100′ long x 2′ tall winding concrete block to slow people down on Jin Zhuang highway. That is what I call a no joke speed bump.
