You're right, it would make much more sense to make the water run uphill, over the road....

My dear friend, Building a bridge over the water no need to block water. As we known, build a bridge on land procedure as following below: 1) Studdy the land by geologist & engineer 2) Put supporting pile 3) Built bridge support (pillar) 4) Put the beam structure across support 5) Connect all the bridge structure 6) Finish all the job 7) Test the bridge 8) Open for use Actually, the engineer buid the bridge over the sea also apply all above 8 procedures. They also need to studdy & get sample from geologist. When put the pile support, they don't block the water. They put hollow pile via special make ship for construction over sea. Then they suck out the water from the middle of the hollow pile, after that, they put cement to get the hollow part become strengthen. The rest procedure from 3 - 8 is same as building on land. How to guarantee? The engineers & geologist are the guarantee .... Hei, they have made a lot of studdy then response to the whole construction job, they are our beam. Offcause there is a lot of issue like you said that "constant motion" , .... , etc. The engineer should come over the issues then make the project start, right? All the issues are being calculated by the engineers & also being solve during the project running.

This is going to be a smart *** comment but it may be what you are trying to get someone to say. Are you wondering why they actually do the act of building while suspended over the water? They don't always build bridges over water. Sometimes they build the bridges on land and then lift them onto the bridge abutments with cranes. If I read your question literally then technically that is not "building a bridge over water" However, most of the time the bridges are much to heavy to lift and that is why they are constructed right over top of the water.

Bridges are cool, but I absolutely agree about the horror of all that needless water WAY WAY down there underneath. I have only one fear in life . . .no, I'm also afraid of squid . . .but, that's falling off a bridge in a car and plunging down down down into a sloppy splat and drown like a trapped rat as the car slowly sinks into the murky, freezing nightmare of fish poop at the bottom of some river.

They build bridges over water now?! Why didn't anyone tell me before I drove my car into the river. Now I feel foolish.

actually bridges or not built over water a stucture integrated by supports which stays over the ground surface are called as bridges

where should we build bridges? Over land? How would we cross the river if we did not?

The whole point of a bridge is so you can cross water, why else?

That way, people can reduce the Force exert on the Bridge. In theis case, the Centripetal force would go downward, and( you'd better illustrate the vectors on a paper) this makes the Pressure of the vehicles moving on the bridge smaller the their Gravitational Forces.

There are construction workers (both men and women) out there who have more balls than you do.
