How to design a dangerous junction
Discussion
See what theyve done here. Instead of a normal slip onto a dual carriageway theyve turned it into a give way junction.
There have been a few accidents

Calls have intensified for a “dangerous” new road layout to be investigated after a rush hour crash.
Yesterday morning hundreds of commuters were caught in miles of tailbacks after a Ford Focus and a Mercedes collided at the junction where Liverpool Road meets Golden Way in Penwortham. Drivers of both vehicles suffered minor injuries.
It is the latest in a series of crashes at the junction since the slip road was remodelled in December so both lanes peter out to give way.

I guess the problem is that making it more obviously a give way, means that more people slow down and/or stop, creating more cases of large speed differentials between main carriageway and slip road.
Always amazes me the people that think grinding to a halt when joining a dual carriageway is a good plan.

Those are completely normal markings for a slip road entering a major road.

The problem with this junction is that both roads are single carriageway until about a quarter of a mile before the junction when they open out to a dual carriageway. You then get four lanes of traffic fighting to occupy two lanes. It's always been chaotic at peak times and until the improvements to the A582 are completed it will continue to be. Glad I don't have to use it every day now.
The main road (where the HGV is) used to be single lane (current outside lane) and the inside lane of the slip road used to feed straight onto the 'bypass' becoming the inside lane. The outside lane of the slip used to merge as it does now.
The problem seems to be people not accepting the change and either ploughing straight on from the slip without giving way (I see this most mornings), or giving way and having someone run in the back of them who didn't expect them to give way (saw this once last week).
I can't comment on the visibility from the slip (not used since the changes) but I suspect its not great, as it was always poor before from the outside lane of the slip.
Overall, an improvement for the main road at the expense of the slip road.

I encountered one of these 'slip-roads' merging onto a dual-carriageway up in Scotland many year ago, and got the shock of my life when the slip road suddenly stopped abruptly like this one did. It's absolutely stupid given that the vast majority of slip roads genuinely do allow the motorist time to merge onto a dual carriageway or motorway. In this instance it's actually made the road far more dangerous for no good reason.
Perhaps the problem is with the council who assign people with the task of road engineering to inexperienced staff or perhaps to staff members who don't drive and have no comprehension of driving, it's no wonder this county is in such a mess with all this nanny state stupidity.

I was waiting for him to be pulled
M6 northbound J34, been like this since it was put in as a 'temporary ' junction after upgrading an emergency exit.
Far more dangerous as it's got a steep up hill 90 degree bend then your on the motorway, no time to look, not easy for a small engined car to reach 70 and visibility is poor due to the bend.
Finally being changes after 50 years !
Just glad it's not a busy junction.

I use this daily.
It is insane.
There will be a fatality, it is purely a matter of time. For people not speeding, a differential between adjacent lanes of 40mph is now routine with confused people panic lane changing. With non speeding oncoming traffic in the opposite direction also doing 40mph all the ingredients are there for a spectacular 80mph plus head on...

This is how it used to be.

The outside lane of the sliproad was a give way, the inside lane carried on and became the inside of two lanes on the A59. There was no need to use the outside lane with the give way if traffic was light and if it was heavy everything was moving slowly enough for people to merge in turn safely. This is just badly thought out and no doubt assuming that slowing everything down and forcing people to stop is making things safer
