N3-M50 interchange

Random · 17-08-2010 6:24pm

this is why the new m50/n3 interchange is a disaster. i'm sure there's more reasons though. this is at the auburn junction.

this shows traffic that wants to go to auburn queue here for an eternity

IMAG0393%20%28Small%29.jpg

this shows that the outbound traffic is a mess because traffic can't actually get across the junction and ends up blocking traffic coming out of auburn causing more delays.

is this how it's always going to be m50? thanks

rolion · 17-08-2010 6:30pm

is going to be a joke...actually they did what they been asked to:free-up M50,no more traffic queuing on the M50...they did it !
they moved the traffic from the N3 / M50 roundabout to...near N3 roundabout area ! ! all traffic going to be affected !

is a fcuking joke of the 2010 ! ! disaster...

does anyone know where the most recent plans are for the junction? i've seen so many at this stage ...

thanks

I think that those lights are to allow a right turn for access to Total Fitness/Connolly Hospital. It is possible that there will be no red for those heading outbound on the N3.

Breezer · 18-08-2010 3:11am

Is it just me or are the lights at the new bridge leading from the N3 inbound to the M50 roundabout deliberately timed so that traffic turning right out of Blanchardstown Village onto the N3 inbound gets stuck at them immediately after going through the previous set of lights? I've gone through several times and every time I've been stopped 50m on at these new lights.

I really hope this junction works. It must be the worst in Dublin by a long way now that the Red Cow's finally sorted. I can't think of any other where so many people routinely bypass the bypass by going through the village (Castleknock).

What a mess the N3 is now at Dunsink Lane inward. You have four lanes at the traffic lights. When it turns green it looks like something from wacky races with the cars changing lanes all over the place just to get ahead.

Moving along the road then, it is also completely unclear where the lanes are ending/merging and where the crap bus lane actually starts. I can only hope this is a temporary situation.

And its still a big mess! I have been traveling home around 5ish from the city center the last few evenings through the park and on auburn avenue,and have notice that people driving outbound on the N3 are turning left on to Auburn avenue and around that white roundabout and back on to the N3!

Auburn avenue is not an alternative anymore to get out of the city!

Surely once the M50 roundabout/Blanch village junction is complete there will be no more queues such as those on the photo as traffic will not be held up getting through the roundabout anymore.

Pineapple stu · 18-08-2010 7:30pm

What happens is buses taxis etc still using the lane now used to get onto the M50 south as a bus lane when coming from town and try and pull in at the last minute where the road splits. It stops cars free flowing onto the M50 and in turn blocks cars at the junction. A motorbike guard was at the split on day and he was sending those that was trying to pull in onto the M50 instead which i had a good giggle at, maybe they wont try and wizz down the inside again

Random · 18-08-2010 7:31pm

happy to hear that about the garda. bus eireanns buses are doing it all the bloody time. i really hope they sort those road markings and finished the bus lane just before the slip down from the train station.

the same problem stands inbound. there should be no bus lane until just after the slip up to the station.

How is traffic supposed to get from Blanchardstown Village (or the area just south of it e.g. Laurel Lodge) to the M50 south? Head up the N3 towards Navan, loop around over the bridge, and all the way back again? Or alternatively up to the Phoenix Park Station bridge, cross over, back past Auburn and onto it that way? Please don't tell me this junction has been permanently designed with no access to the M50 south from the village...

On the flyer it suggests going via Snugborough, then using the N3 inbound.

Or they can go via castleknock and auburn avenue.

It says no right turn onto auburn avenue from N3 inbound, but can they turn right from the travelodge towards N3 outbound and M50S?

Either way, it's to be welcomed. One less local road into a major interchange, letting them join a half mile either side of it, is better all round.

Ordinarily, I'd agree, but not here. What is supposed to be a local road has become a major Dublin traffic artery in recent years and it can't cope. Whatever about Blanchardstown, Castleknock needs to be bypassed completely, not have more traffic funnelled through it en route to the M50. I'll reserve judgement until I see the whole system in operation, but deliberately routing traffic through a village sounds nuts to me.

Isn't that the whole problem. Over development of D.15 and meath beyond. All coming in the Navan Rd or Castleknock road to get to city center. Indeed the main road the Navan Rd has gone from two lanes to one lane due to the bus lanes. So there actually less capacity into city center than there was 10, 15 yrs ago. Now theres a ruddy great interchange junction bang in the middle of it.

apologies if this has been asked before, but does anyone know what the timeline for the M50 Northbound off ramp onto the N3 is ?

Will it stay reduced to one lane until October ?

Due to have three lanes opened on the M50NB at some stage this week & the rest of Junction is due to be fully opened on the 31/08/10.

Posted on 20/08/10 on the M50 upgrade - Phase II, thread

The slip from the M50 SB to the N3 Outbound will definately open on the 31st along with the rest. On the mainline, I expect the third lane under the N3 to be open some time next week as we want as little TM as possible to be in place for the opening. On the day of opening the off ramp will be one lane, i.e. the auxiliary lane, leaving 3 lanes Northbound

What the Story with the N3-Out to N3-Out flow through the M50-N3 junction for the last couple of days?
If it stays this Bad, the Junction will have to go down as a Failure!!!

BostonB · 26-08-2010 5:19pm

I think you are seeing what Breezer said. Traffic going on/off the M50 has priority at the expense of everything else. So everything else backs up. The problem with that is that there are 3 other main local junctions here.

1) N3 traffic going straight through.
2) Castleknock traffic in and out
3) Blanch traffic in and out

There minor traffic also going into total fitness/hospital, but the volumes I'd guess would relatively minor.

I usually avoid all those junctions. Out of curiosity I tried it one day last week at about 7pm and it took about 20+ minutes to get through heading out on the N3. In fact I don't think I've passed through there at any time recently where there wasn't a queue somewhere.

Stark · 26-08-2010 5:30pm

Hopefully when the remaining freeflows open, they can play around with the green time for N3 outbound or remove the lights entirely.

BostonB · 26-08-2010 6:04pm

Theres always hope. Maybe we'll be pleasantly surprised. The other junctions Red Cow, M1/M50 seem to move ok.

brandodub · 26-08-2010 8:08pm

Went through there today at around 1720 and all lights were out on the roundabout. (Travelling M50S->N3 OB).
Obviously not as bad as inbound N3 traffic uses the new freeflows but there was major backups on N3 outbound and M50S off ramp. I'm hoping its because its not fully open yet that its still this bad.

Even AA Roawatch gave it only a cursory mention( 'heavy delays' like the old Red Cow Roundabout a few years ago).

Fingers crossed .......

:(

mackerski · 30-08-2010 1:39am

Earlier this evening I drove N3 inbound-M50 South and back again. Some speed limit roundels have been painted on the lanes at two locations:

Here across all lanes (towards M50 and towards city)

And here on the not-yet-open ramp towards N3 outbound.

As far as I could see, all were marked with the number "30" with no units. This is not only a daft limit, it also conflicts with all signs currently erected on these sections. More silly mistakes or something more worrying?

Stark · 30-08-2010 10:28am

I took the "30" to mean 30mph. Which is obviously a bit stupid given that we don't use those units anymore.

BostonB · 30-08-2010 10:36am

It can't be MPH.

That it doesn't match the signs. LOL.

Stark · 30-08-2010 10:53am

The signs were "50km/hr" from what I remember. That's how I figured the roundels were outdated "30mph" roundels like you see coming into villages around the country and the like.

Jeebus, how hard is it to get this stuff right?

If it is 30km/h then someone needs to be horsewhipped. That is way too low. I thought the 50hm/h limit on the freeflow from M50 to M1 Northbound was silly. There's not a hope of anyone actually respecting that.

If there will be 30,then i expect to see parked ,on the side of the road, a white van OR a red van OR a green van,with a clear line on the back door's window and AC unit on the top...mobile radar camera unit ! They'll share it with the one from Lucan N4 ! They needs to recoupe the investment ! !

Re traffic,i still maintain my affirmation that is a very bad design...

Chris_5339762 · 30-08-2010 5:48pm

The 30 limit going from N4E to M50S is needed as those slips cant be driven any faster, simple as. Dunno if thats the case here though.

Im sure the overturned truck at J3 a few months ago had a part to play in setting this low limit.

The funny thing is that the next speed limit sign you meet is down at the Ashtown roundabout. Are we to go at 30kmph till there?

I dont get ya, the 30KPH is marked on the new slip not opened yet, which goes outbound towards cavan, not inbound.

It can indeed be taken faster. Not a whole lot faster, and not in all weathers, but that's blanket speed limits for you.

It's on the N3 inbound overpass as well. I saw it this morning.

Is that not just for vehicles going onto the m50 SB, rather than going to the city centre

It's also marked on the N3 citybound straight-through route.

They should have signs on the ground saying "no heart attacks" to prevent this sort of thing.

No - as stated in my earlier post, it's on all lanes. Though it's just possible they don't all read the same.

I thought it was 30 on the N3 inbound as well, although I was in such a shock at how ridiculous this is, my mind might have been playing tricks on me.

Steviemak · 30-08-2010 8:22pm

MODS: We seem to be having the same conversation in two threads

Breezer · 31-08-2010 2:49am

"30" marked on N3 Inbound for both city-bound traffic and M50-southbound traffic from what I can see. About 100-200m after the 50km/h signs. "30" also marked on the M50 Northbound-N3 Outbound slip.

Daft limit, whether it's 30km/h or 50km/h. 80 to 50 and back to 100 once you hit the M50, on what is a relatively gentle freeflow curve.

ecaf · 31-08-2010 1:59pm

Is the new off ramp at N3 junction coming from M50 south to north going to open tomorrow?
They keep changing which lane is opened or closed on this slip without warning, and I don't see any notices up telling us. It would be handy to know when they are opening up the 2 lanes / 4 lanes now. I thought it was to be down to 1 lane until today?
Can't see anywhere on their site that shows updates either. I mean an update the day before, I don't have time to log on before I go to work.
Thanks!

bigar · 31-08-2010 2:26pm

I see these "30" more as an advisory speed limit as they do not seem to be supported by any of the required speed limit signs.
To be honest they could serve a purpose for drivers unfamiliar with all these bends and trafic lights straight after them on some points. Better to take it slow.

I agree. I've been using the N3IB->M50SB freeflow and I've had several near misses with people changing lanes at the VERY last minute;stopping in lanes when confused and flying through the Yield sign from N3OB->M50SB.

IMO there will be a major accident at this interchange very soon:mad:

Not a major one, but yesterday I already had a car hitting me from behind when I was standing at the red traffic light at the Dunsink Lane junction. Fortunately only some small scratches on my strong beemer. The other car was in worse shape

So the 30 km speed limit to me sounds really good.

Yeah - with a limit of 30 the car behind will shunt you before you even get to the lights. As you'll be in motion, the difference in your speeds will be lower, meaning a less dangerous impact.
