You have to admire the architects and civil engineers here.  Someone apparently decided to take a whimsical approach to road works and built these two bridges to look like the road is a part of a roller coaster ride. One is twisted and the other steep like a mountain.  I am sure there is a reason behind this madness, like port access to large ships, all I know is that for motorists this road is not only something interesting to look but also to drive on.
