N8/N25/N40 - Dunkettle Interchange [open to traffic]

Me too, about the signage for the M8 on the N40 which indicates the M8 is accessible from both lanes of the N40, resulting in some drivers making a last minute dive across lane 2 of the N40 after they exit the tunnel.

Yeah, but Google Maps has always been pretty crap as a navigation app. It's usually the last to get updated any time a road opens.

If the signage was correct, this would be okay, but it's not, so it makes the problem worse.

The most important instruction is "Use right lane for Dublin". I think a two panel "All other routes | Dublin" gantry would be the clearest and safest option. Everyone else has a chance to move lanes, but Dublin traffic is kind of screwed if it emerges from the tunnel in the left lane.

Its just pure bad driving there thesedays. People forcing the merge, people tailgating in the overtaking lane. Result: crashes.

How the merge atvRathcoole on the N7 is done, it ain't rocket science

N7

I think it might help by forcing people to continue on the merge lane due to the barrier separating the lanes. There's still a long merge opportunity without the barrier. I'm not sure there's the same amount of room at the Bloomfield Interchange but it might help.

The issue at Bloomfield is there are 2 lanes from the N28 running parallel to and unseperated from the N40 with chaotic merging onto the N40 from both.

The 2 N28 lanes should be merged into one while separated from the N40 by a barrier, like on the N7 near Rathcoole. It is only after the emerging of the two N28 lanes should the resulting single lane be able to merge with the N40.

Only having one lane merging, a la N7, should reduce the present chaos which is resulting in the current high rate of crashes in the area.

Two separate merging lanes a couple of hundred metres apart is still one too many, considering the volume of traffic on the N40. Is it not better to merge the two on the N28 into one and have just one merge onto the N40.

I do know it’s only one lane the whole way from the roundabout at Rathcoole, I was only mentioning that location as an example to demonstrate how it is done in a better way than simply plastic bollards which don't survive for long.

Back in 2007 I'd say it got a bit interesting.

There is a school of thought that says to make roads safe, make them feel dangerous. Maybe they were ahead of their time back in 2007!

and Mahon

Traffic on the N28 on ramp at Maryborough Hill, coming up and down the hill, which I have never seen/haven’t seen in a long time. A big problem was the second people got to the end of the ramp and onto the merge lane, they were trying to merge. No one (except me) would go to the end of the lane and seamlessly merge in. It led to a standstill as cars were braking trying to squeeze in at the start of the lane. As discussed, same happens at the merge of N28 (specifically the right hand lane) and N40. Everytime I go to the end of the lane and I get in easily without having to stop

Oh definitely, I should have made it clear I still do it safely, and yield to traffic on the mainline. I always dread driving past the J10 on ramp eastbound, same with the N27 at its junction with Mick Barry Road

Not sure what time you were at but there was an accident between Mahon and Bloomfield after 6 that slowed everything down, wonder is the mile or so between Mahon / Bloomfield / Douglas Flyover statistically the most accident prone area in the country? Certainly feels like it!

Did anyone email the Road Construction team about the signage in the scheme? And if so, did anyone get a response?
