M1 New Section of D3 (three lanes) at Swords

Irish and Proud

Fingal Co Co has published plans for the widening of a 2km section of the M1 to Dual 3 Lane. The section is between J2 (Airport) and J3 (Drinan). An interesting point, the specs for the Northbound carraigeway is for 3 x 3.65m lanes, while those for the Southbound carraigeway is for 3 x 3.5m lanes. Also, the Hard Shoulders are down as varied - so maybe they'll stay at 3m generally. The Median Strips are 1.0m as usual.

What I'm guessing is that a 100kph limit will be imposed for Southbound traffic in order to keep the pressure off the M50. If that's so, can one conclude that the standard specs for a 3 lane motorway carraigeway are:

1 x 3.00m Hard Shoulder
3 x 3.65m Lanes
1 x 1.00m Median Strip
Total Pavement: 14.95m?

Another interesting point is the two concrete median barriers proposed. The link is as follow:

two separate collisions again this evening.
Leading aside archic means of words(!), when will the blasted thing be finished?

The name in Irish from which Drinan is anglisced is Draighneán which means "Blackthorn"

Logainm gives a list of names the area is recored including:
Drynam -- map 1740
Drinham -- Rocque's map (18th century)

see http://www.logainm.ie/16953.aspx -- hit Taifead Scanáilte.

Discussed here previously.

I be of the Middle classes..... and I'd have taken Drinan rather than that idiotic bastardised name they have come up with. I live not far away, and did not even realise that was the case. I will be referring to it by it's correct Gaelic title in future.

Nope. Drinan was modified to "Drynham" by developers who built the surrounding housing.

Drynham sounds very Englishshire periody property porn - whereas "Drinan" is pure Gaelic.

We know which image sells to the Oirish middle class!

Eh... yes, this is clearly on-topic Mod :rolleyes:

Carawaystick

according to http://www.fingalcoco.ie/Roads/SchemesonDisplay/SchemesPreviouslyonDisplay/DrinanLissenhall-Proposed3rdLane/

from looking at sheet50 from the os, Drinan is south of the junction on the Swords/Malahide road with the road to Seabury.
The town land where the works start would be Nevinstown East or Marshalstown or Barrysparks. there's no townland boundaries on these maps

There is no Drynham marked as a townland.

Seems to be both!

A bit of an Oilgate/Oylegate situation. If you local with pretensions you probably call it Drynam.

How about:

New Sections of D3 (three lanes) for M1

Shouldn't it be "6-Laning M1 Drinan-Lissenhall"?

Maybe merge and change name to reflect the ongoing work is from Drynam to Lissenhall?

M1 Swords Improvement Scheme and Lissenhall Junction Upgrade

Have I created a duplicate thread? :rolleyes:

Perhaps, though one could argue that this thread is specifically bout one scheme, the other thread originally started about the initial proposal but broaden out. If you want we can merge the two. Obviously historically on major schemes we did maintain seperate threads for different sections of motorway been built (M6 Athlone to Galway etc.)

The Estuary bridge is more than wide enough - it has space for a third lane in the centre as part of its design.

I see the issue has been teased out!

This is exactly what I was wondering about.

Wild Bill

Hope I'm not getting this wrong

The Drynam to Lissenhall Widening is from J3 (Drinan/Drynam) to J4 at Lissenhall??

(Which means it includes putting six traffic lanes across the bridge across the Broadmedows Estuary)

Dingatron

The last few pages of this thread explains it all.

This is the first thread I have ever started so excuse me if I get everything wrong.

I noticed the widening of the M1 past the Airport as far as Drynham Junction has been completed and came upon this scheme in a list provided by the forum's greatest contributor, Mr Sponge Bob.

Past the (new) Drynham exit heading north the mainline reduces from 3 lanes to two; common abroad but the first time I've seen this in Ireland. (Usually here the inside lane converts into a filter lane, goes up a ramp and is lost).

The arrangement looked "temporary" - and this scheme seems to bear that out.

Anyone got any maps, links, pics - whatever - to this scheme?

Another crash this evening.

looked like the rear of the 2 cars was written off - it gave a Focus a real stunt up the bum.

I'll bet theres no-where else like it in Ireland at the moment - a 400 yard stretch of road thats claiming about 10 vehicles per week. If it wasn't so seriously it'd be comical!

Middle lane rear-ender.... just looked like a very minor tip. Had been a breakdown and log-jam there a bit earlier according to AA Roadwatch.

it is absolutely rediculous. Its getting worse.

I don't think its exceptional to say that there are 1-2 collisions per week these days; sometimes more.

2 this week, 1 the previous week, 3 in a row the last week before christmas

fridays collision was in the middle lane, back from the merge a bit - 2 cars in bits, especially the one behind - bonnot was in a big V.
Last week there appeared to be 5 cars damaged one of the days.

I'm actually getting sick to the teeth of it! the old way was actually better and less stress.

I think the problem is AFTER the merge. for some reason the traffic takes hundreds of yards to get going even though the volume isn't near capacity, and the inside lane is the faster one, which makes it even more dangerous as you have lads diving down both the outside AND inside lanes.
I think the problem is that slower/careful drivers stay out of the inside lane for the Swords exit, and then end up inadvertently in the overtaking lane after the merge with lads jumping all over them, inside and behind.

(did I mention I was sick of it??!)

I don't think a 100kph limit is a big deal to be honest, it's not for very long until you pass the Lissenhall exit.

It sets a pattern of road improvement to achieve speed reduction. If it eventually made D3M to Ballbriggan, Julianstown or Newry will it then all be reduced to 100Kph?

Traffic moves along at 120KPH for 21 hours of the day here at present, without this "improvement".

100kph I'd say - all lane widths will be 3.5m which would be very tight for 120kph.
Regards!

I'd be surprised if they lowered the limit. The main reason the limit on the M50 is 100 is not due to narrow lanes, it's because of close junction spacing. The distance between Drinan and Lissenhall is 4k.

Out of interest, has this existing dangerous right lane merge proven to be dangerous in practice now that it has been there a few months? (when I initially saw it, I did think it was a recipe for accidents but now that I've driven it frequently, there is a long lead time for merging and with plenty of advance signage combined with regular driver familiarity, are such concerns still warranted? Has there been reports of collisions/near misses etc?

it is absolutely rediculous. Its getting worse.

The yellow strips represent at-grade (road level) pedestrian/cyclist crossings. Apart from the M1 mainline (North/South road), the junction is at just one level.

Regards!

Traffic mixing with ped/cyclist at a "rural" junction like this, looks dangerous to me.

Is it rural enough area that ped/cyclist is extremely low?
