This mountain highway has the biggest U-turn in the world
It's in the province of Guizhou in China and it's designed to help people who've missed their exit go back the other way as safely as possible
We've all been there at some point. We've all for whatever reason (usually loss of concentration or navigation sending us the wrong way) missed our exit on the highway and had to go all the way to the next one, come off, turn around and go back the other way. This can especially be a real pain if the exits are pretty far away from each other. Wouldn't it be easier if you could just do a great big U-turn somewhere between two junctions so you didn't have to go through all the trouble of adding so many extra miles onto your journey? Well, somebody in China clearly thought about this because there's a mountain highway in the province of Guizhou that has exactly that!
If it looks like a very simple solution, that's because it is. It's quite literally a big, elevated loop that runs over the top of both carriageways. The loop section has a speed limit of 40 km/h (around 25 mph) so anyone who needs to use it will have to slow down quite a bit as they enter it, but it looks like there's plenty of distance for drivers to brake. Considering that this stretch of highway is in a very mountainous part of China where there are very few opportunities to turn around should you miss your exit, it's something that's going to save drivers who regularly use the highway a lot of trouble!
Is this something that should be implemented in other parts of the world? I'd absolutely say so, especially in places that are very mountainous and have very few places for drivers to turn around if they've missed an exit. I'd imagine it could be implemented very well in the more mountainous regions of Europe and North America, for instance. The Chinese engineers who came up with this simple and brilliant solution definitely deserve to be commended for it!
