New Road, new 50mph limit, in Wales
Discussion
There's a mad flurry of limit reduction at the moment. 40 to 30 and nsl to 50mph in some daft places.
Is it councillors making themselves feel useful or a wider plan? I used to love driving but since lockdown i don't want to leave the house because of everything, I thought leaving the eu and lockdown would have made tinkering and pointless activities become less common but if anything its accelerated.

No surprise this is in Wales. The M4 is 50 in huge parts now and it looks like Cardiff council spent their time during lockdown making half of roads in this city drop to 20.
It's very frustrating but the worst bit is how the police camera vans turn up on the same day as a limit change to pick people off before they even know it has happened.

I would never argue for unsafe driving or speeds of course. But I feel like the powers that be are doing their best to stifle this country.
We need to be productive and competitive. We need efficient infrastructure where people can move around and get things done. Quick, safe and efficient.
Lady in the article mentioned that after all the expansion work her journey is up from 10mins to 25mins.

Seems there is a subset of PS that wish to de-invent the motorised vehicle and wind the clocks back to some sort of imagined, bygone utopia.We need to be productive and competitive. We need efficient infrastructure where people can move around and get things done. Quick, safe and efficient.[/b]

There are plenty of roads far worse than this new by-pass that are and have been 60mph limit. It seems this policy is intent on denying the freedom of automotive transport.

The roadworks are still ongoing, so she’s facing congestion. We don’t yet know how long it will take her once completed, however there will be two lanes not one, so there’s nothing to suggest it’ll be over 10 mins. I use this road regularly and over the past 3 years have seen the project develop, it’s incredibly impressive. Whatever the speed limit ends up being, it’s a 4 mile stretch of road, so potentially a time saving of only 1m 12s at 70mph! Compared to how traffic used to back up at the now obsolete Brynmawr roundabout, which could queue for 5 minutes plus at peak times it’s an absolute non story.
And then have the cheek to want to tax tourists for coming to their country.
There are many roads in Wales I dislike (the M4 for starters as it is closed just about every other day) but the pinnacle for me is Carmarthen to Lampeter- the limit changes every couple of miles and his has speed bumps on an A road FFS.

Know that road very well. Used to commute on it regularly. Early morning it's good fun. Past the speed bumps there's a nice hill climb section which is enjoyable. Coming back though it's horrendous, especially if you get stuck behind the T1 bus. There are a few spots to pass but locals don't seem to like doing it themselves. If I go back up that way now I go via Llandeilo and Talley instead.

The M4 is a joke though. 50mph on any dual or motorway is farcical.
Had the displeasure of coming back this way on Saturday through the ongoing roadworks. Even the roadworks are limited to 40mph (I guess this is so when it goes up to 50mph, the locals at least notice something has changed?!) it's dire, and feels far too slow. What you end up with is lots of bunched cars, where someone's' interpretation of 40mph is actually more like 36mph whereas everyone else is trying to go ~ 44mph on their read-out. So you get trains of cars all stuck behind one other driver holding up a queue. Once it opens up to a dual carriageway this problem should go away, there will be room to overtake - but you're introducing a new problem with HGVs overtaking passenger cars, which they will. If an HGV goes through a 50mph zone it does so on the limiter - usually 56mph. It'll be disastrous.
Then as another poster has flagged up, they have the audacity to put on the matrix signs - "slow down, air pollution kills!"
Vote for stupid people and stupid policies is what you receive.

They are also repeating the lie that a 50 mph limit is good for the environment.
It is not as many cars are at their most fuel efficient over 50mph
How are you reaching that conclusion?It is not as many cars are at their most fuel efficient over 50mph
The most fuel efficient speed varies by car and depends on drag, rolling resistance, the engine and gearing. From memory one study showed that the most fuel efficient speed for an Audi A8 diesel was 52 mph.
For a large number of cars if the speedo is showing around 55 mph (bearing in mind they overread) you are probably at the cars most fuel efficient speed.
If it's going to see significant HGV usage then 50mph is appropriate because it regulates flow a lot better. You will get more vehicles through the same stretch of road if everyone - including the trucks - moves at the same speed. Less phantom braking, less racing to get past other vehicles, and with reduced acceleration and unneccesary braking, comes greater fuel economy.
Remember the old Top Gear "one tank of fuel" challenges? They didn't seem to vary much according to speed (Clarkson in the Jag at 75mph) but it was the braking and then accelerating back up to speed that caused the fuel to drop.

HGVs are limited to 56 mph, not 50mph, and this would likely be showing as close to 60mph on many car speedos.Remember the old Top Gear "one tank of fuel" challenges?

Further highlighting that if you are setting speed limits in accordance to HGVs, or air pollution, the limit should be 60 mph not 50 mph.

That increase was during the roadworks. From reading the article I think the speed limit was 50 before the works and they're reinstating it once the works are complete. People are surprised because the road is going to dual carriageway so assumed the limit would go up to 70mph.We need to be productive and competitive.

How long is this stretch of road? What would the extra 20mph save in time?
The Welsh government and councils really do hate motorists. Also announced no new road projects by the Welsh government which had been fully backed by Gretta.
It's quite difficult driving here now. You have to be on the ball for speed limit changes on the same bit of road for absolutely no reason what so ever.

But I wouldn't think it's likely that any cars would be more efficient at 70 than 50? Maybe I'm missing your point.
