N25/N30 - New Ross Bypass [open to traffic]

The gap appears to be closing slowly but surely

^^^^^ Have those photos been given the John Hinde treatment?

I had a sudden thought. Is there, by volume, more concrete in this 900m long bridge than in all of the buildings in the town it is bypassing?

Concrete volume comparison is academic & not relevant. Latest pics very good and informative. Progress may seem slow, but on quite a complex project as this, haste is not an option.
We've been waiting for this bridge for a lifetime and a few months delay is nothing. It's shaping up to be a great deal more impressive 'in the flesh' than the photomontages.

Of course it's academic and irrelevant, but it's nevertheless an interesting question by way of diversion.

I have no grounds whatsoever to back this up but I would bet that there's a lot more concrete in the town than in the bridge. New Ross is not huge, but it's not a little village either. I'd be interested to see calculations from someone with the relevant knowledge!

I'll have a wild stab at New Ross, but I have no qualifications in the area
Population of 8,000 people and with an average of 2.7 per house = just under 3,000 houses.

I've seen a figure of 50 cubic metres of concrete per 'average' house.
So 150,000 cubic metres for housing.
And then I'd triple that for all the other stuff, shops, schools, halls, concrete streets, Hanrahan bridge, piping, the mushroom, etc.
So 450,000 cubic metres in the town by my guess.


How much is in the bridge?

27,000 cubic metres

I assume this will be the longest bridge in Ireland north and south, but where does it sit in the scheme of things if you were to include Britain?

They should keep it under construction for the next 5 years so we at least have some construction to look at.

From my own limited experience, it'd be well down the line, behind both Severns, Humber, even the Dartford Crossing.
It may officially be a 900m bridge, but there's only 190m of river being spanned.

I've been a bit spoiled over the last 10 years that the longest bridge in Ireland has been built in my old home town and this monster

Ok so this bridge is a minnow outside of Ireland then.

Someone was on the beer and prescriptions nice and early.

887m - making it the longest bridge of its type int the world. [Google Extrados bridge].

UIM, it will also be the longest and highest bridge in Ireland....

At that angle, it looks mostly done. Not in reality though!

Humber Bridge was promised by the then Prime Minister, Harold Wilson, in order to win the Hull by-election in 1966. Connecting Hull with the emptiness of Lincolnshire was a local issue

What exactly has been the delay here? Needed more engineering than expected?

I cant see it being delayed until next year as has been mentioned here. Novemeber has been also mentioned and maybe that is more realistic.

I pass it a few times a week and there is always a noticeable difference in progress as each week goes by.

Thanks for all the brilliant drone work to date

The camera angle can be deceiving

prunudo

Camera angle may be deceiving but there definitely seems to be an increase in speed of work. Looks like one of the gaps, the one closest to the shore, is nearly joined up.

Just wondering if the bridge is likely to be painted or otherwise treated so that it doesn't stain to a dirty brown color, as concrete tends to do?

I drove down by/under the new bridge today. Seriously impressive/imposing structure in real life!

Great photos. Thanks a lot for sharing.

Going to be fine structure when finished. The n25 is lucky to have 2 big bridges in a short stretch (i know its down to the topography). Most other roads in this country are lacking big engineering pieces.
