And if you mandate the steel, concrete and aluminum used be made in the UK it could help support those industries.
And it would reduce trade costs between NI and the UK.

Apart from all of the other logistical issues that others have listed, it's flatly untrue that deeper bridges have been built.
Currently the deepest one under water is the 25th of April bridge in Lisbon, at 70 meters below the water. This was a giant construction project which lasted over a decade, and serious planning for close to 30 years before that... over a span of about 2.2 kilometres.
The Irish sea between the 2 proposed point is, at the shallowest, 120 meters... but that place is a bit further south. The actual point everyone is proposing is actually about 160. Yeah, so in order for this bridge to be built, it would have to be spanning over a depth double the current world record.
In a big ocean shipping lane to boot, so you couldn't get away with it being down low which is typical of longer bridges. And remember, this is under water. With currents, and wildlife, and boats, and waves. That stuff messes with bridges very much, to say the least.
I'm sure it's possible, that said. And if it was part of some big Keynesian project, then I'd 100% support it. But don't underestimate the challenge. It would be giant, serious national investment that would take over a decade to build... at the very least.

Actually the biggest obstacle to the Celtic Crossing would be Beaufort's Dyke, which is a trench between Northern Ireland and Scotland. It is 30 miles long, 2 miles wide and 200–300m deep; it cuts right across the point of the proposed crossing.

If it ever happens it will be a train tunnel. Simply that.

You can't as Obama found out in 2009 it violates WTO rules for government projects to only use local steel.

I cannot find anything saying that but there is this:

Which would be triple the current world record for the deepest bridge. Damn.
You'd just span over such a trench then. 2 miles, while huge, isn't impossible for spanning.
Having each of those pillars be under about 160 meters of ocean water would however be a considerable obstacle.

It's issues like this that lead me to strongly suspect that such a project would end up horrifically overbudget and late.

The House of Commons should be proportional, while the House of Lords should become a local representation. The House of Commons enjoys a kind of seniority over the House of Lords, so it would be preferable if the House of Commons were elected by representation.

The Eiksund Tunnel in Norway is 287 meters deep. The Seikan Tunnel 240 meters deep.
Now I cannot find a good list of bridges by water depth but some oil platforms are built in water 300 meters deep. Nordhordland Bridge crosses water 5,000 meters deep.
So deeper water has been dealt with.
But sure it would be a Keynesian mega project and engineering challenge, but that is much of what makes it interesting. And sure it might take a decade or more to construct but that is fine, creating jobs and demand for a decade or more.

Tunnels are not bridges. Oil rigs are not bridges. Nordhundlund bridge is a fucking pontoon bridge.

Ok but hear me out... UK can have a little super mega hyper bridge, as a treat, but only if it's, like, a railway bridge for after the trains get nationalized.
