It's just a random image on the web. Not sure when or where. Actually, such a construction has been explained once before; if you build the bridge straight, the slope might be too steep. The roundabout is meant to reduce the slope.

Huh?

Depending on where you build roads/bridges there is a limitation on the max slope allowed. For places that can ice up, the slope is much smaller than somewhere hot. From this angle it doesn't look like much change in elevation, but think of most bridges having 4-5 meter clearance means the elevation drop here is steep. That raised section have a train line going under so must be about 5 meters above grade going to a road on surface. So really no matter where you are, will need to build that circle.This is nothing new. Just post for fun.

Logically, when engineers build a bridge, they of course have studied and find the best solution for it. The circle alone may cost hundreds of thousand if not millions of dollars to build. They would not build it for no reason. Looking to the photo with bare eyes may not tell you all the truth. Further, looking at the lower right corner, there's an entrance that may require the height of the second part of the bridge to keep low. Whatsoever, as I have said from the beginning, I posted the image for fun only, not to mean to cause a chaos in argument. Thanks everybody for viewing my post.
