Pont Jacques Chaban-Delmas, Bordeaux

It's a bridge. If you want to get to the other side of the river, this will be important to you. Do note though that a considerable section of this bridge raises by a significant amount (to enable river traffic to also pass to the other side of this bridge), and when raised, your progress to that other side of the river will be hampered. So if the bridge is closed, prepare yourself for either a long wait or a slight detour.

This bridge is HUGE! I was wondering what those four pillars are while I was still far away but then realized that its a bridge. I've yet to see this one in action like when theres a boat crossing and the bridge will lift 'the road. There is also a possibility to go up. However, I think you need special permit for that. There were a few people- I think its their field trip, that went to the top. I tried to go with them but was not allowed to.
