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

People in the right hand lane don’t realise they need to yield to people in the left hand lane on the N28 merge. So when they do realise, they try to shove into the N40 lane

As has been said so many times, the Douglas flyover is a serious pinch point.

The slip from the N28, Jct.9, needs to continue as a lane through to the on slip at Jct.8. Some ANPR recordings might prove that a significant amount of the traffic from the N28 exits at Jct.6 therefore the extra lane between those two junctions would alleviate the merging and volume passing over the existing two lanes of the Douglas flyover.

Building a third westbound lane, from the end of the existing merging lane of Jct/9 to Jct 8 shouldn't be overly expensive or disruptive if it were to be built using stilts and a prefabricated deck instead of widening the existing earthen embankment which carries the existing two lanes.

hi does any one know the range of the go safe vans

Overtaking lanes should ALWAYS merge back at their end into the primary lane. Unfortunately, there seems to be no official policy on this, or if there is it's either not widely known among those responsible for setting out road marking or they simply ignore it. It is not uncommon to see a mixture of primary lanes merging to the right (into the overtaking lane) and overtaking lanes merging to the left (into the primary lane) on the same road.

Merging lanes, from another road, should always merge to the right, following the give Right of Way rule. As said merging from to the left (into a potential blind spot) is a recipe for collisions.

This. I see it all the time. People look in their side mirror which are obviously angled back from the N28 slip - and which creates a massive blind spot for the N40W lane then and hence accident after accident at the back of the RPH. Meanwhile, the speed checks that everyone gets caught at are at the diverge to the N40E where, to be knowledge, there are never accidents.

At one stage, they did have bollards to force the N28 merge to N40W much further down but they got taken back up. Said it too before, but I distinctly recall an article saying the Douglas flyover had footings put down for a lane 3 when they built the new Tesco carpark and created the link road within Douglas.

Ya, If i have that right, it would make the queue look shorter but make the journey slower with the amount of extra merging. Correct?

There will always be queues at peak times - the only solution to that that actually works is to give people a better option than driving. The goal of this interchange isn't to remove the queues: it's to prevent heavy traffic in one direction from blocking traffic that's going all other directions.

In fairness that sign for the M8 doesn't help much, it can give the impression that you can access the M8 from either lane, and you've only got about 70-80 mtrs to the turn-off.

The sign I posted above is after the tunnel heading north towards M8, N25 from Dronehawk's video from yesterday;

That sign for the M8 should be offset like below (UK I know). And why does the arrow have to point downwards?

In the interest of consistency, the sign for the M8 exit should be on the right of the N25 sign just like the sign for the N8 is on its left, not across the top. As said, it can cause some, who might not understand the signs properly, to think both lanes lead to the M8.

I dought its that far on the range of the camera going by what's being said on here that it's less the 60m

So the M50 can have City Centre with other signs saying other cities, but the N40 is unique so can't..

Link K N25 to N40 is going to be continuosly backed up at peak times with multiple lanes being funnelled into one.

Douglas Flyover is the weak point. I’m flabbergasted that people didn’t think this would be the case.

The M8 South to City movement is a complete non story in comparison.
