Where is it?
M58 junction 5, the main junction for the new town of Skelmersdale from Liverpool's northern radial motorway, the M58.
It was nominated by Paul Berry.
What's wrong with it?
Take a look. It's what you'd get if you took a bag full of all the exciting junction elements you liked best and then tipped them out randomly all over the floor.
There's a pair of loop ramps that get M58 traffic to and from the A577 in the wrong direction, there's the half-roundabout thing south of the M58, and there's the sliproad that's an unclassified road for most of its length. There's the fact that the majority of movements involve doing a large lazy circuit of the round bit at the bottom. I'd like to write more but every time I look at the diagram I just start to weep uncontrollably.
Why is it wrong?
Who knows. The best excuse I've heard so far was that the M58 here was originally an A-road, built with Skelmersdale and then absorbed into the M58 route. As far as I'm concerned this goes no distance at all to explain why, to get from eastbound to northbound, I have to complete a figure of 8, or why there's some very unnecessary conflict created between the loops on the M58.
One person who worked on the upgrade scheme to turn this road into the M58 said, with a sigh, that it was a junction designed by an architect. Old maps show that, once upon a time, a useful sliproad existed from westbound to northbound that was removed for reasons unknown. It seems that, like the rest of Skelmersdale's road network, this is an experiment that went wrong.
What would be better?
Well, let me see. I think the first thing on the list has to be levelling the entire thing and starting again. There's so little traffic on any of the roads concerned that you might as well install a mini-roundabout with peak time traffic lights and have done with it: at least it would provide a direct left-turn off the M58. Ideally though, a simple roundabout interchange would be installed, which is really what should have been here right from the start.
Right to reply
You say you weep when you see this junction. I use it daily so have no tears left!
I see innumerable accidents and near misses from one 'peculiarity' you don't mention. Traffic joining M58 eastbound (from the loop ramps as you call them) has to suddenly give way [there really is a Give Way sign and markings!], with only about 20 yards of slip road, to traffic exiting the M58 at motorway speeds. They both have to use the same bit of tarmac as traffic joining joins 100yds before traffic leaving leaves. And if that sounds confusing, I suggest you try driving it ... or actually not!
I also feel junction 5 Pimbo/Skem is bad junction, the slip road off meets the slip road onto motorway, twice I have had to slam on because cars coming onto motorway have not realised that this it is a slip road. I was forced back onto the inside lane of motorway and luckily there was no cars approaching, I don't know whether there has been any accidents at this junction but feel they need to do alterations to this junction before someone is killed.
At the very least, put the "start of motorway" sign at the give way, and keep the speed limit 40 or less until you reach the give way, so that they will have more time to actually stop. As it is, the start of motorway sign starts too far back, lulling drivers to start to quickly accellerate up to speed before suddenly, there a warning for a give way, forcing them to slam on the brakes.
It's even worse!
You'll notice that both of the sliproads south of the M58 merge with local roads. In fact, the eastern industrial estate (Prescott Road is its perimiter) has no other roads giving it access.
It has to be a criminal bit of bad planning. I used to work at Skelmersdale and a regular occurrence were 44 ton trucks going the wrong way around a one-way industrial estate! I once also saw a car going the wrong way - the driver, from nearby Wigan, had come to give us our fork lift truck training! A very badly designed bit of road.
I use this junction several times a week to travel to the Gym. It regularly causes me to sweat more than the workout (but maybe that's me).
Perhaps the main issue for me is the ease with which fast- and slow-moving traffic can meet. Leaving the motorway westbound, you have a 40mph sign 20 metres down the sliproad. Another 20 metres further on, the East Pimbo ringroad hits the sliproad, with all its' attendant artics. After a sharp 100degree left round Walter Edmundson Haulage you are required to give way to traffic out of Skem that's essentially coming from behind you.
Having negotiated the loop at the bottom of the junction and avoided the trucks leaving the West Pimbo loop you're confronted by a large expanse of tarmac which is 66% westbound on-slip, 33% West Pimbo loop and 100% unmarked.
All this excitement takes place at varying speeds between 40 and 70 and within the space of 400 metres. There's too much going on in too small an area to have any confidence in your ability to arrive at your destination unscathed.
To reiterate Stuart and Catherine's comments, the real terror of this junction is the eastbound on / off slip. I can guarantee that the first time you use the on slip, you won't realise that you have to give way. You will have a deeply religious moment when you pray that nothing is coming down the off slip at motorway speeds. Subsequent uses replace this moment of shock with a feeling of helplessness as you approach the give way sign with no real view of the motorway to allow you to judge whether it's safe to continue. This experience is such that I occasionally continue a mile down the A577 to double back and use the alternative, and much safer, on slip (or, alternatively, avoid the final 2 miles of the M58 altogether).
What could be done to improve it? Well, a roundabout on the A577 feeding the eastern eastbound on slip and the eastbound off slip would allow closure of the ridiculous western eastbound on slip. It would be relatively easy to connect the East Pimbo loop to this roundabout via Chequer Lane, solving the eastbound exit slip problems. Beyond that, some sensible landscaping, signage and a few litres of white line paint should have this junction working properly. That, alas, doesn't address the simple fact that both the concept and execution of the Pimbo industrial estates and their fast, one-way, two-lane ring roads is deeply deeply flawed.
After 4 hours Motorway driving from Reading, hitting the Pimbo masterpiece to take Stannanought Rd (why the name?) to Ashurst (estate) is a wake up call.
This junction is a triumph of mobility over access - you keep moving without arriving. An unmentioned vice is the lack of access to Upholland Railway Station for Park and Ride.
The answer is a proper hierarchy: M roads mainly connect to A roads then to B/C etc but no bad short cuts!
My girlfriend, a non-driver, asked why anyone thought this was a good idea when we were on a bit of a drive last week.
I, despite being a traffic professional, couldn't defend it. The sightlines on all of the sliproads are nothing short of awful, and the less said about the standing start onto the M58 the better...
A definite resemblance to Munch's "The Scream"...
The main reason M58 J5 has such an odd layout is that it was originally designed as a variant on a cloverleaf junction (very rare in Britain but sadly all too common on the continent and in the USA), and several critical parts of the junction south of the motorway are missing.
Most significantly, the A577 was meant to continue south through the junction, and merge with a road that was never built; the not-quite-a-roundabout at the southern end was designed to accommodate turning movements, and was not meant to be the through route.
In addition to this, there was an M58 east-A577 north sliproad in the original plans (built, and since removed) and another loop in the south-west corner, between M58 west and A577 north. As the A577 was never extended to the south, the latter was considered redundant and was never built.
A diagram of the original plan can be found here.
Why the designers chose to use a cloverleaf as their template, I really don't know; as many previous commenters have noted, it's an incredibly dangerous way to link two high-capacity fast-moving roads, and was regarded as obsolete by the time Britain started building motorways. Perhaps they thought it would make Skelmersdale look more American and therefore more aspirational.
My daughter lives in nearby Crawford Village and I get completely befuddled everytime I use this junction. I'm relieved to hear that it isn't just me.
It seems like demolishing the lot and putting the A577-M58 links onto a roundabout interchange (along with whatever local roads, access roads etc exist) is the answer to this mess.
They call Skelmersdale the town of roundabouts, when here there is none in sight
It sort of looks like it was designed in two halves, but while the designers of the northern half thought it was to be a cloverleaf, those on the other side thought it should be a dumbbell...
The worst motorway junction I think I've ever encountered in this country. That 'slip road meeting another slip road' abomination is little short of criminal. It'll never get redesigned though because there's not enough traffic to warrant it, in the eyes of planners
It is mentioned that there used to be a sliproad for westbound to northbound traffic, and there also looks like there was possibly another for eastbound to northbound. If those two slips were still there it would be an almost acceptable (if not a tad strange) junction.
And please tell me that there is nowhere else in the country with 'Give Way' signs on joining a motorway?
Being pedantic I have to say that traffic joining a motorway is supposed to give way to traffic on the motorway!
I’m fairly sure there are others on urban motorways. Leeds and Manchester have Give Way signs on motorways, I think. There may also still be one at the exit from Washington Services on the A1(M), which is more similar to the M58 example.
Im sure that there are give way signs on all motorway services slip roads joining motorways.
No, there aren't.
