Yes.

Big changes now starting to happen. I see main bridge supports now poured and precast walling sections being put in place along the sides. It's starting to put a shape on things. No opportunity to take any pics though.

What's the speed limit gonna be from M50 out to where the old 100 limit applies?
When it's finished.

I'd like to think it will be 100kph all the way to Naas but don't recall seeing that anywhere.

My bus from cork last tuesday turned left before works and picked up the n4 via lucan would it have been congested at 11.30 in morning or was the driver taken no chances. Coming home I passed via newlands x at 20.30 no hold ups.

Unlikely, given the bad/dangerous design of the junction, for example merging from M50 southbound to Bowstring Bridge. 60km/h on that stretch is too much for the 'skills' of the average Irish motorist.

Bowstring Bridge?? Which bridge is that?

SimonQuinlank · 28-02-2014 4:50am

Bridge over the N7 from Luas to Monastery Rd.

Bit much - the length of road, 200 metres, provided for this 5-lane merge is way too short, skills or no.

Ideally, the merge/diverge lanes on the southside of the N7 at Bowstring would be removed and moved here.
This would have other advantages: It sorts out the left-in-left-out junction here. The current lanes are on a steep hill with a tight bend. It would make it easier to link in the proposed long-distance cycle lane around the back of the Luas P+R which will use the Bowstring.

How long before we are using flyover, I'm guessing Nov at latest.

They seem to be doing a good work with the flyover. The construction of the supportive structures seems to be progressing well-at least to me. The supportive pylons are there on both sides of traffic lines and the wall seems to be taking shape really well. It wouldn't surprise me if they get the flyover sorted much sooner

Well, We'd hate to disappoint, so here is a grab from my bike-cam this morning. You can see from the vans position that the landfill for the "Ramp" is well under way on the dublin side.

Wow, it's going faster than I expected.
Thanks for photo.

But honestly, we need Kreator. Where is he?

Dunno, no more photos here http://www.skyscrapercity.com/showthread.php?t=1599158&page=9 since August

rameire · 21-03-2014 11:41pm

two pics from today

1 pic is of the south side of the junction, and its supporting pillars for the beams that will bridge the gap.
on the south side of the junction, they have put in a good bit of the new curbing for the slip road that will run parallel to the flyover.
I assume this will be part of the next phase that will open to assist the building process.

pic 2 is of the northern side of the junction, not really clear, taken from hands free kit so didnt get to mess with it.
they have also put in a lot of new curbing on the northern side of the junction that would have been originally the bus lane.

Red arrows in lights! About time, far easier to read than two full red circles which one can be mistaken for your direction. May not be too long for red arrows to make an appearance at O'Connell Bridge and other busy Dublin junctions.

I agree. However, these will not be used consistently.

Geogregor · 23-03-2014 1:44am

It seems they are really steaming ahead.
I suppose precast beams will be used rather than structure cast in situ?

Really has to be to allow the road underneath stay open. Even if a box mould was put in place, the risk of concrete dripping on to a car would be not worth it. Precast can go in in a night.

I think it has probably more to do with speed of the construction and the fact that this bridge will be really straight and simple, no bend of the structure.

Bridges are often cast over the active roads below, if necessary.

I've never seen it done in Ireland at all, not over an active route.

We've had cases of installing precast go horribly wrong as well though: http://historical-debates.oireachtas.ie/D/0552/D.0552.200204170099.html (that'd be the R449 now, support beams for a dual carriageway collapsed on the railway line below)

If I'm not mistaken, it was done in Limerick to facilitate the N18 passing through Ballykeefe over the active Ballinacurra road.

That bridge was built for the road that was originally there but was under it during construction if I remember correctly.

smokie72 · 23-03-2014 4:09pm

Can anyone answer this. Why are there only 4 supporting pillars on the west side of the newlands cross compared to 6 on the dublin side of the junction. Are they going to add more supporting pillars later on? Not enough room at the moment to add another 2 pillars to that side of the road?

BuzzFish · 26-03-2014 11:33am

Here is a driveby from this morning. More to give those who don't pass regularly an update...

What a great addition to the thread! Thanks a million. Id suggest starting a new thread if you want to scrutinise the rules of the road, as I'm probably not the best person to ask!! :rolleyes:

It was fairly hectic today when I was passing through after 5, but to be honest I think that is just your standard Friday rush hour traffic coupled with congestion further up the N7.

Really looking forward to when this flyover is built though just to get rid of that last set of traffic lights!

Looks like they will have to drop the left turn at newlands to build the last 2 supports for the flyover.

I think they are managing the traffic very well and I don't think the construction work is adding much in the way of additional delay at the moment.

They are building slip lanes to the left of the video picture. So lanes will be moved to those new lanes to help with adding the extra pillars I believe

To see the above slip lanes and phase 3 which assists in building the extra pillars

I'm thinking this change will have the greatest effect on traffic Dublin bound as everybody will probably try get into the right hand lane which reduces to 1 lane after the lights

That document was well hidden. I'm surprised that it isn't one of the first items in the list of search results for "Newlands Cross" in Google. Thanks for that.

agreed 100%. I think i mentioned that myself previously in the thread. This is where the traffic headaches will really start. Looking the other day, the tarmac is being laid currently for the new lanes (to the left inbound).

well, it took me over 1.5 hours to get from Amiens St to City West on Wednesday, even though I left at 5pm!

Jayuu · 07-04-2014 10:52pm

Came into the M50 last Thursday in the evening through Newlands. Maybe it was just a one off but while traffic did move along and we weren't delayed that long I would advise peple to avoid the left hand lane (which eventually becomes the M50N turnoff) until after the traffic lights. When I stopped first in the traffic there was a truck beside me in the middle lane. By the time it got through the lights I was still nearly 200m away from them in the left hand lane.

As I say it was my first time doing that journey so maybe other people who do it regularly might have different experiences.

But on the other hand I've hadn't issues coming from the Northside, around the M50 and out to Citywest!

ongarboy · 09-04-2014 10:33am

Anyone needing to use the M50NB coming from the Naas Road may also wish to consider using the Grange Castle/Lucan turn off (just after Citywest turnoff) and then join the N4 to bring you back onto the M50 (or indeed into town via Heuston).

I always use that anyway to get over to Clonsilla/Clonee and avoid the M50 and it's tolls as well!
