No. The boat displaces the amount of water equal to its own mass (the Archimedes Principle). In other words, a 5,000 pound boat will replace 5,000 pounds of water that used to occupy the space where the boat now floats. That 5,000 pounds of water is "pushed" off the ends of the bridge. There is the same pressure/mass/weight on the bridge supports whether the boat is there or not.

Yes, Alladin, you are right.
For some of the others, there is indeed such a bridge. It is part of a canal system in Europe where the man-made canal intersects a natural river which is at a much lower elevation. So over the river, the engineers built a water trough type bridge through which the canal flows. There was a photo of this in the internet about six months ago.

Add the weight of the boat to the water that is how much weight the bridge must support.

No. Aladdin gave a good explanation. See his answer.

yes, because of waves which make boat.

Assuming (big assumption), that you are not an idiot, would you please restate your question in a way that makes sense.
