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

King Kelly

This week's local papers have the listings of CPO's for the New Ross bypass so some relief in prospect at the bridge in town.

Are their any images of the new river crossing available? I'm told it will be the highest bridge in Ireland. True? Where it's due to join the Waterford road at Glenmore is certainly a high point.

Do the cables go from deck to deck through the pillar, or deck to pillar with an end anchored in the pillar? I'm guessing the former, but I don't know.

I know little about bridge design, but Wikipedia is your friend. Extradosed bridge design.

deck to deck through a series of cable box "saddles" in the pillar

from the wiki link
"As a result of these characteristics, the "stay cables" on extradosed bridges are not treated as such by the design codes, but are instead considered as external post-tensioning tendons that have been deviated upwards from the deck to the towers to increase the superstructure's load capacity over the main supports.[2]:1 Extradosed bridges frequently extend this approach by making the extradosed tendons continuous over the towers via saddle supports and using anchorages only at the deck connections, significantly simplifying the tensioning operations.[4]:33,61"

Bridge deck drawing

Unusual to see a drawing in cm?

M or mm are generally used, no?

josip

BAM probably charge a few million extra to display in mm or m.

It looks like the one on the 28th was taken from higher up, making the gap look much narrower than 3 weeks earlier?

I know someone who works with BAM there. It's the Spanish company, Dragados, who use cm and metres. BAM use mm and metres. The same occurred when building the bridge on the Waterford bypass.

Of course cm is the agreed standard and it's no problem at all.

Each side of the bridge only 4.25m wide or am I reading that diagram wrong?- Surely not one lane each way?

I assume the 210 on each side is part of the road too, assuming it's like the one on the Waterford bypass with no pedestrian/cycle access.

The bridge is 6.35m wide on each side it's going to be a dual carriageway with hard shoulder can't wait to drive on it next November

November? Great! I've been going between Wexford and Waterford through that hell hole New Ross for nearly 20 years so cant wait.

I drive it a few times a week and sometimes i find it the longest hour of my life. I reckon the new bridge will take 20 mins off the journey. The amount of slow moving vehicle's drives me mad.

Yeah. It will definitely have a significant impact on travel time.....and stress. Nothing worse than sitting in those damn queues.

It'll probably have a knock on effect to the Barntown roundabout In Wexford though and that's atrocious in the evenings as it is.

Two people in the last few days have said to me there is an issue with both ends aligning and that some Spanish contractors who were on site have been sent home while this is looked at. No idea if true or not and could be idle talk. Is work ongoing at present ?

Ah yes, the hardy perennial that is the "bridge not meeting in the middle".

Has probably been said about every bridge ever, and has defintely been said about every bridge discussed on boards.

Don't worry - someone's pulling your leg there.

Is it true they now working 24/7 to completion ?

The traffic in ferrybank (Waterford) in the mornings is horrible. After an hour drive hitting that traffic is a nightmare.

Mod: If you want to make jokes, there is a thread for it. Of course it was deleted because it followed a mod instruction to leave the jokes out.

The occasional joke is OK, particularly if it apposite, and funny. However, the umpteenth variation of that same joke becomes tiresome.

Just to let folks know that the current Google satellite imagery is very recent. Possibly 6 weeks or so. I know a field in it that's close to my house that was only recently ploughed for the first time in decades.
Sat images are very clear!

Interesting. There's only about 3/4km of the entire scheme left to do, the bridge and it's approaches. The rest seems effectively complete

As of today at the pink rock site. Looks like they're working through the bank holiday weekend.

Looking at that image on googlemaps, the gaps are only 100 metres. So they are much closer now. Very interesting.

Will they have the equivalent of a topping out ceremony?

Thanks for that.

According to Google Earth the latest satellite imagery is 2/2/19, which looks about the same as I remember the bridge back then.

It has come on a long way in 3 months..

As it should be for major infrastructure to be honest. Even if the labour cost is 30% or 40% higher, I feel that cost in the short term is worth the boost to the economy from having schemes, not just this one, in play sooner.
