S Curved Bridges
S Curved Bridges
(OP)
Just a general question. I haven't designed bridges before, so hopefully someone with experience in that regard can give their thoughts. I'm wondering why this bridge and others are curved in an S shape like the image linked below.

I have my own ideas of why this may be, but I'm interested to hear from others.
Thanks!

In this case from Wikipedia info and plan view:

And Google earth map it shows low water level acroos most of the bridge

So looks like they were following the natural shallow water contour + picking the best points for the ferries passage.

The 'keeps you awake claim' seems a little odd to me just because I've certainly driven on very long stretches of very, very straight highway that were much longer than this bridge.

In the end, a bridge may be dictated by the geological and marine conditions and sometimes by aesthetic reasons (color, shape, preservation, clearance) to get it permitted especially with depth and clearances are the major criteria. Many major European bridges have extreme designs to adjust to the conditions that exist.

"The Confederation Bridge was opened only 10 years ago and is a masterpiece of technology. With a length of 13km (!!!) it is among the longest bridges of the world. Interestingly, it is not completely straight, which according to the official website was done to ensure that drivers do not lose concentration when driving for more than 10 minutes on the narrow lane."
It would be interesting to hear if that is actually the case or just a story for the public
