Angled pilings are inserted into a special template that is carried on a barge and driven into the sea floor until they can't be driven any more. Then, a concrete slab is poured in a steel reinforced form on the barge bonding the pilings together and forming a large concrete platform with places to stand and secure the pier structures. The pier structures are positioned very accurately on these slabs a certain distance apart (usually 143 feet). Then steel reinforced concrete beams are placed between the pier structures and secured to them. Then the road is built on these beams. There is quite a bit more to it, but I can't write the whole book here.

Building bridges IN THE SEA would be a ridiculous concept surley you mean OVER THE SEA as a bridge in the sea would be a very wet road!!

There are many ways, Like the artificial island thing.
But I'm presuming you mean how do we cast concrete or bolt piers under the sea.
Either pre-cast. When we make it on land the sink it.
Or in-situ. Concrete will set the same in seawater as in air.
If there is any bolting to be done, it depends on the job, we'll either pre-fabricate the girder and attach it to a concrete base. Or send down divers.
Once the columns are in place, everything else is done off of these. Systems are put in place so that all work is done above the water. Except on the big ones where barges will bring in pieces and cranes will hoist them up.

you create this large pontoon that is anchored in place and build a bridge across a series of those until you get to your destination..

Just like how you build castles in the sky

It's difficult unless you have bedrock near the surface to put the pillons on.

by making 'artificial islands' that support the bridges weight, thats basically it

Hang them on "skyhooks".

...............in the sea? Wouldn`t it better if they were `above` the sea?
