What was the point of the new Dunkettle layout?

scrotist

Traffic is as bad as ever heading towards the tunnel.

Would be faster walking.

It's not finished

It has moved the traffic bottlenecks to the kinsale roundabout and other choke points.

For traffic coming from the East to the tunnel (the site of most of the unresolved problems) - yes it is and has been for some time now, other than adding *more* traffic via the Dublin loop in the coming days.

If people could stop crashing into each other at Bloomfield, it would certainly help.

Traffic from the east is a disaster now and as bad or worse than the previous layout. This is mainly as it is trying to funnel all that the traffic into a single lane through the tunnel.

Norrie Rugger Head

If people would get into lanes on time (where there are dedicated lanes). Especially relevant coming from M8

Use all lane space where there are zipper merges it would help. Instead people hog one lane and refuse to allow merging from adjoining lane

Switching lanes in the tunnel is not allowed and causes upstream breaking too

The problem coming from the East, is that the ~75% of tunnel traffic coming from this side is only allocated 50% of the road space (one of the two lanes) - simple maths. That cannot be fixed while maintaining free flow for traffic from the north. While some will maintain that there was bound to still be peak time queries, there was normally only queues at peak time anyway - so what was the bloody point in doing it?

Is Castlemartyr worse at peak times now? With traffic getting their faster? Not done it in a while.

Anytime I have gone near the tunnel from west or east lately, it's been great, with no stops at all. But that's off peak

It has definitely gotten a lot worse than the previous layout. People aren't using the zipper system, traffic from the left lane from little island try to push in too soon over a solid white line when you are trying to watch traffic merging from the right hand lane - need eyes on either side of your head! People are then crossing the solid line in the tunnel esp HGVs as they are moving slowly and want to get out the way for when they exit the tunnel. Accidents now at Bloomfield as the bottleneck has moved on to there. My boss went to LI the other morning and came back through, he said he found it extremely stressful and doesn't know how I do it every morning! The traffic lights before were 100 times better.

8:25am on a bright morning and it is completely blocked up at all the choke points. Nothing to do with the way people are driving.

So official works are completed today. Interesting to

read:

"Concerns have been raised by local councillors that traffic queues approaching Dunkettle from its eastern side are getting worse.

They have also claimed that the traffic flow from East Cork into the tunnel and into Cork City has not improved since the Dunkettle works were undertaken. "

Which backs up what people are saying here. But if people crossing continuous white lines can't follow simple traffic rules then it will only make matters worse. What if cameras were mounted at such points to monitor behaviour and issue fines & points automatically for anyone breaking the rules? All it takes is one selfish muppet to cause a crash and grind the whole thing to a halt.

dory

Ooh didn't know there are cameras. At 8.40am I see traffic is flowing well into the tunnel from the west. That seems to be some improvement. Coming from Midleton and heading west will be the trouble. I don't get why so many crashes happen at Bloomfield. Is it the little bend in the road that catches people?!

There was a crash at Bloomfield yesterday which was the primary cause of all of that.

People try to cross the two lanes of the N40 in one go.....poor merging....

Which begs the question, also asked by @dory above, what's causing all the accidents?

Chris_5339762

A very poorly designed merge at Bloomfield, at an unlit junction (because of the nature area), that is on a bend and a slight hill with heavy traffic.

Also people can't drive.

I bow to your superior driving skills, but consider this as a plausible hypothesis.

A lot of traffic coming up the back Douglas village ramp at that hour of the morning, attempting to merge with a lot of traffic coming from the east. At the top of the ramp looking in their mirrors for gaps to merge with the oncoming traffic, they do not see that traffic ahead has suddenly stopped or slowed because of the choke backing up from the Kinsale roundabout. And suddenly, they're into the back of the car in front.

Does that work as an alternative?
