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

Cantona's Collars

When did the new roundabout at the Enniscorthy side of the bypass open? Passed through it today. Part of the existing road is now completely redundant except for access to a couple of houses and fields with one end blocked off.

It's open a while now, about 4 or 5 months.

Just after Christmas, frustrating to see that lovely dual carriageway going over the horizon isn't it?

Some photos I took within the last hour on the Kilkenny side.

Was down there today and took some poor-ish pics that I won't bother posting.

It's a fabulous project! It really is impressive in the flesh - it's a BIG bridge, and it's LONG! It's also quite stylish - when the cable stays are completed it will look very well.

Lots of 'tourists' there this afternoon - nice to see such interest, and can't wait til November!

A few not great phone pics taken today from the top of Slieve Coillte:

Great shot showing the lovely elegant sweep towards the far bank.

Quare close now though lads!! ;-)

It's probably the most over-enginerred infrastructure ever built in Ireland but no one who uses it will complain!

Can't wait to drive over the world biggest span 230 metres

Ah sure, it'll still be around in 150 years, and still a stop for college civil engineering field trips too

Out of curiosity, how is it over-engineered?

Harry Palmr

Okay over-designed.

I think it's a fantastic looking bridge. No doubt it'll be a bit of an attraction too. After driving up and down that road for the last 20 years it's not a bit over designed when it can remove New Ross from the equation. More power to it.

Hoof_Hearted

I think it's a progressive design, and beautiful of course, but it's forward thinking that brings about such immense projects. I'm all for it and can't wait for a spin over it, and under it

Jeremy Clarkson is to cut the ribbon, I hear.
No wagons allowed on the bridge till he's gone.

Thanks, but I'm not sure I follow. What should the design have been? (Genuinely curious)

One of these would've done the trick

In all seriousness though, probably a cable stayed bridge much like the Waterford bypass.

I like the design of the New Ross bypass more as it fits in with the natural valley, it's not superimposing on the surrounding area as it's pretty low slung in comparison to a cable stayed bridge with a large central tower which would've jutted over 300ft in the air.

It's a fine looking bridge. Now,how about something similar for Dublin bay to complete the M50 ring. They could build it high enough so anything could pass under it.

Probably be cheaper and easier than the proposed tunnel.

I'm not an Engineer by any means - I just have an interest in this particular bridge as I travel the route a bit....

I've lifted this directly from Wiki https://en.wikipedia.org/wiki/Extradosed_bridge

The extradosal bridge form is mostly suited to medium-length spans between 100 metres (330 ft) and 250 metres (820 ft), and over fifty such bridges had been constructed around the world to 2012.[4]:16–26 Whilst incurring many of the construction costs of both the cable-stayed and girder bridge types, extradosed bridges can deliver material savings to offset much of this penalty.[1]:387–388 They have frequently been adopted when overall height, navigation clearance, or aesthetic requirements have made the cable-stayed or girder alternatives less feasible.[4]:15, 135–136

The bridge is cable stayed - Extrados is a version of the type.

The Waterford Bypass bridge is 112m tall - the RFK bridge is 36m at its tallest.

From what I can read, it was the most cost effective, least intrusive and yet visually appealing option.

How is it over-engineered or over-designed? (Again, genuinely interested.)

Me thinks because it's not in Dubland then by this alone it must be overengjneerd and overdesigned..sure those cuclchies don't need an extravagant bridge

Harry Palmr

Don't take me too seriously or literally. I'm not complaining either God knows. I would have expected the N25 to have been fobbed off with a much less ambitious, lower structure on a much shorter bypass nearer New Ross cos that's what us yokels tend to deserve in the eyes of Dublin!

It is not an extravagant bridge, it is an extradosed bridge.

See here.

Id say he meant what he said like......extravagant.

Has the bridge deck completely joined up at this stage?
