    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.

    They cant do that, advisable speeds can only be used in denominations of 5. So it would be 35kph. They also cant be used with a white background and a red circle, this is for legal limits. Advisable limits must be used with a plain white, on a rectangular sign.

    Answering my own question about Blanch Village -> M50 South: I've found the best way is to use the old roundabout, heading towards the city, then immediately go left towards Dunsink, immediately right at the lights to Auburn junction, turn right at the lights there and onto the N3 Outbound -> M50 South freeflow ramp.

    I plan to use Blanchardstown Road South -> N3 East -> M50 South.

    Bit of a trek if you're coming from the village itself though.

    Going to Dunsink Lane is a bit of a trek in the other direction.

    From the village maybe you could go down to the hospital and get onto N3 East and then M50S (until that option is removed).
    The alternative is to go up Main Street, past Garda station, toward Blanch Centre (Westpoint gym side) and then turn right over N3 and then onto N3 East.

    I saw the queue of cars trying to turn right onto Dunsink Lane (in order to go across to Auburn Ave) so I wonder if your idea may be slow because of this. I am sure it depends on the time of the day. It could be quicker to go to the overpass at Phoenix Park station if the Dunsink Lane part is busy.

    What's wrong with the first bridge? I did this a couple of days last week. (I was coming from Coolmine Rd.)

    You are right. I suggested the other bridge because the Snugborough Road traffic lights are so slow - but if you go through the junction (as I suggested) you might as well turn right and use the route you mention. My mistake.

    I was on the ped bridge last week and I noticed an unused pillar in the middle of the M50. I wonder if it was for the planned ped bridge.

    I also saw the 30km/h limit sign for M50N->N3W. If the curve was such that warranted a low limit, I wonder why they didn't bank the curve to compensate?

    I was always under the impression that that was for a pipeline of some sort!

    If you look at the original drawing for the junction, you will see that the new ped bridge was supposed to be at the location of that pillar.

    OK, I forgot about that original plan. :o

    Now it's a new stand for some artistic sculpture. A dead Tiger perhaps :D

    I can see why people miss the little slip to Cavan/Navan and end up going to the lights on the M50. Tonight was the 1st time I took the M50SB to this junction since it opened and it really isn't that well signposted.

    I knew about it so was prepared to take the left lane but because of the bend you don't see the sign for the little slip until you're practically on it. If you were new to the junction you could be past it before you realised it and end up stuck at the lights

    Welcome to Dublin :D

    Used this for the first time today going M50 Southbound > N3 Outbound. It is a badly signposted in that it is only as the road divides that you get the actual signpost to say that the N3 outbound traffic needs to be in the left lane (as opposed to where you might expect it to be give that you are eventually turning right).

    As I was driving up there was a car which veered into the lane right at the very last minute. Thankfully he was a good bit ahead of me but I'd say he gave the guy whom he cut in on a bit of a shock. Its a pity that they haven't given better advance warning for the junction. It wouldn't have been too hard to do so.

    As for the 30kmh limit I think that's a bit extreme. I was in a stream of traffic doing around 50-60kmh and we had no real problem with the bend. I wish they had put a 50kmh limit here as people are more likely to respect reasonable speed limits. If anybody did slow down to 30kmh here they'd probably end up with a couple of irritated drivers behind them.

    I have found the signposting to be more by experience.

    On the M50 North off ramp you have a split which are both posted N3 one with Castleknock and the other for Blanchardstown. Bit confusing as Castleknock is not strictly on the N3 plus CAstleknock is accesible from Blanchardstown. Would be better if was posted for the city.

    On the N3 north approach to the M50 junction the sign for the south bound lane is badly sited and causes confusion. I saw an ambulance have to do a last minute cut accross the chevrons otherwise would have missed it.

    Then there's the mismatch between lane markings and overhead signage on the N3 when heading citybound towards the junction. It requires you to swerve into the correct lane. There should be better road markings to prevent this. There is similar problems south of the junction with poor markings for the lane merges.

    Plus, why do they have "Connolly Hospital" followed by a H symbol when they could just have Connolly followed by a H symbol. Leads to very cluttered signage.

    I don't that would make sense. Its usual to give the direction regardless that the destination isn't actually on the road displayed.

    Perhaps...

    N3 (west) - Blanchardstown
    N3 (east) - Castleknock
    N3 (east) - City Centre

    + 1. Sure you could run faster than 30kph :rolleyes:

    indeed, Irish road signage is possibly the worst in western Europe as its littered with mistakes, inconsistencys and is generally hard to read and often lacking in information.

    :D

    The unfortunate thing is that he was probably following the signs and was in what he thought was the correct lane only to find out at the last minute that the signs are wrong and he had to do his last minute panic manoever. (it doesn't excuse his tantrum though)

    This happens to me inbound on the N3 most mornings. People heading into town following the signs will be in the middle lane until they find out about 50m before the end of the lane that the middle lane actually takes you over onto the M50SB.

    Castleknock hasn't never been on the N3 and was never signed on the old N3. One wonders should it be a signed destination at all given that there are other destricts of the greater Blanchardstown area that should be signed.

    even so, it would be less confusing if it had the word City above it - I don't believe that it has.

    Yep its a disaster alright.Seen many cars and trunks getting caught out.
    Had many cars slip in on front of me the very last minute.

    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.

    As someone who uses both N4E to M50S and N3S to M50S, there's no comparison between the two. N3S should clearly be 50; I think this is pretty clear to be honest.

    But then again this is Ireland; speed limit on the ring of kerry from Killarney to Kenmare 100KPH:confused:

    I don't see how it matters that Castleknock, or Blanchardstown aren't on the N3, neither is the City center either. Its a useful direction to show IMO. As would the Phoenix Park.

    Anyone know if there are any aerial shots of the upgraded junction floating around (or any of the others on the northern cross for that matter)?


  • Registered Users, Registered Users 2 Posts: 69,538 ✭✭✭✭L1011


    Is the partial painting out (English language only) of Castleknock on some of the signs here a recent thing? Noticed it there on Tuesday...

    While not an aerial shot, OpenStreetMap has up-to-date road layouts (e.g. N3/M50 junction).
