Secrets of The Motorway - M4 (Part 1)

[@PatGilliland]

Ineffective interchanges, ghost slipways, old airfields, a colliery, bizarre footbridges and a newly restored diving tower that can't actually be used - Perfection!

Hello, How the devil are you. I hope you're enjoying the M4.. As you'll see, we ran out of daylight, it rained most of the day and traffic was crap. It was certainly a challenging day out but we got there. Part 2 will be out next week so if you haven't already, get subscribing so you don't miss it. Some are asking why the random GTA5 clip.. yeah this didnt work out as well as I'd hoped.. In GTA5, when the game needs to go from day to night for a mission, you get a quick time lapse... as the video quickly goes from day to night I kind of stole that idea. Was a bit crap in hindsight but it's done now :D Thanks for watching, commenting, liking and generally being a wonderful bunch. Enjoy the rest of your week!

Beautiful! As a regular M4 user in the late 80’s to mid 90’s, this was a blast from the past. You didn’t mention the very serious accident in 1991 between J 14/15 east bound … I had passed through at around 6am in thick fog, and arrived at work in Farringdon around 8.30am … the team were both worried and shocked as the accident and 10 fatalities /51 injuries was all over the news, with reports of the carriageway melting from the fires … I was ignorant of this until arriving at work! Added fun-fact - this accident happened very near to the village (Lambourn) my dad was evacuated to during the war, after the house he lived in at Hillingdon had the roof blown off my enemy aircraft … Further fun fact - I now live in the Hawkes Bay, New Zealand! So seeing your shenanigans on Britain’s motorways are just fab! I can reconnect with my memories and youth! Looking forward to part 2!

[@briannem.6787]

the bus lane doesn't increase travel times. The bus lane, while it ran, would've been the highest capacity lane of all of them- a bus is only the length of 2 cars and the gap between them, yet holds at least 20 passengers. So, the majority of people actually have their journeys speed up, which encourages more people to take public transport, which means less cars on the road. I understand that car enthusiasts are reluctant to see investment in public transport, but more people on buses means, for one, you have nice empty roads, and secondly you only need to drive when you want to. (There's better educated people than me saying the same thing, though. Not Just Bikes, for example.) Thus, a bus lane was probably a good investment to make. Taking a lane from car traffic isn't an issue because in return you get much increased capacity. Personally I think it'd be a good thing to do to most motorways, at least those that see traffic jams, as it allows the buses to get past a traffic jam. The reason it was pulled up? probably either the buses tended to go via other routes and so it was underutilised, or a bunch of car users complained and a politician had it pulled up, to try to get motorists to vote for them. However, usually projects like that go better than this one did. However, the bus should be on the on-ramp side so it can easily enter and exit. Unless the bus uses separate slip roads, which some systems do use.

[@AutoShenanigans]

I didnt say the bus lane increased travel time to be fair. Whatever the reasoning, this is a clear misuse of public funds and no investment is a good one if you remove it shortly after. It's a straight up waste of money that probably could be used for far better things.

[@briannem.6787]

@@AutoShenanigans good point Yes, they should've put a bit more thought into bus lane placement beforehand, rather than cutting it a few years later

[@I_Don_t_want_a_handle]

It was a Zil lane pure and simple. It benefitted no one as there was hardly ever a bus on it. It was, however, open to Prescott's Jags ...

[@Johnketes54]

Probably means increase travel time for the cars

[@Johnketes54]

Not enthusiasts crap public transport,About 5 miles away loads of offices were built 65/75 only a few parking spaces for the bosses or managering directer,Everyone one else use the buses well cheap 13 pence for miles subsidised by the council,But Thatcher came along with her father's grocery shop mentality and privatised them losing the subsidiary and decreasing the amount of buses,So people "resort to car's" and now the parking,So had to pay to park while at work decreasing people's wages further on unnecessary ownership of cars and their parking,Car companies were happy oil companies,Garages and the local council in parking revenue except the office workers and we are still there now with onboard WiFi and charging sockets for phone and computer,Fancy coloured display at bus displaying bus time usually mirror the paper one in the crappy shelter,So who wants to use a bus

[@IndigoJo]

That bus lane on the M4 was also used as an Olympic lane during the 2012 games; only traffic serving the games (diplomats, athletes and their entourages, etc) were allowed to use it. That explains why those signs with arrows and all three lanes saying "M4" above them are there; the offside lane was marked with an arrow and an Olympic symbol. As for junction 8/9, I've had sat-navs call it "junction eight ninths".

[@redskinperes3508]

that small detail of the bus lane is so important on the planning. I can't believe that none thought about it. xD

[@pdsnpsnldlqnop3330]

Fab episode. You can date any building in the UK by its materials and 'see' how towns grew. For instance, on the M4, a market town will have local Cotswold stone in the heart of the town, then, with the canal arriving you get slate, then, with the railway you get brick. You can keep going all the way up to the present date from these cues. Serious detail about the original Severn bridge, it was workers peeing in the box section when it was being built that led to the corrosion problems. There was nothing wrong with the construction or the materials, it was the addition of considerable quantities of urine that led to doom.

[@AutoShenanigans]

wow..great info!

[@MauriceHotblack]

Curly wurly bridges were generally built for farmers to get their livestock from one side to the other when the motorway cut through their land.

[@Jim-Scott]

Blimey, that was manic! When I was a kid my mother used to drive us the length of the M4 every half term to visit relatives (she's of Welsh origin) then when I first passed my driving test I seemed to be doing that same journey every couple of months taking my mother and grandmother to the funerals of all the aunts and great aunts (and some great, great aunts) that we'd spent the previous years visiting.

[@ulazygit]

Crikey! Sounds like my family … Welsh family from the valleys … family trips, then courting a young welsh lady, inevitable funerals and also the odd welsh stage WRC trip (every year during the 90’s and early 00’s) … even several business trips to Monmouth late 00’s, prior to migrating to the other side of the world!

[@TheScubapez376]

Wow Jon can’t believe you missed out the recently upgraded Jn16, or the M32 Jn19 and M5 interchange (Jn 20). FYI RAF Welford also included US Nuclear weapon stockpiles, but not sure if that’s the case today. Also there is a proposed junction between 18 and 19 which is to link the Bristol ring road near to where you see the DPD depot but there is a lot of local residence opposition to this so it’s unclear if this will ever get built but it was expected to relieve congestion at the M32 junction (19). 19 also used to be a proper roundabout, before closing a side of it so traffic is no forced onto the A4174 if you need to use the junction to change direction, you can still see the evidence of its roundabout past and used to be the only roundabout with motorway regulations that I was aware of.

[@brianartillery]

I used to love going on the Chiswick flyover as a kid, in the early 1970's. Occasionally, I'd 'go to work with dad' on a Saturday morning. He was a site manager for a civil engineering company, and any day out with him was an adventure. Sometimes, he'd drive 100 miles just to see if a machine had been delivered on time, and was working, or we'd go to a site, and watch chimneys being demolished, or he'd have to take measurements on site, with a theodolite, and I'd stand holding the measuring poles. No laser measures in 1971. A theodolite, some graduated poles, and a notebook. As we lived in Suffolk, and a lot of his work was in Kent, Sussex, Hampshire, and often, Dorset, we'd cut through London. Dad loved driving, and, I suspect, never believed the 'Straight Line' maxim, as he'd go all over the show, in his Ford Cortina Mk.II (white with red seats). A lot of the time, we'd go over the Chiswick flyover. And it was thrilling - being high up, with interesting industrial buildings either side - I loved it. And so, I expect, did my dad.

[@philwoodward5069]

I used to commute from Langley (Berkshire) to central London via the Green Line coach. The coach always had between 30 and 50 commuters on it and the bus lane allowed us to jump the queue to get onto the Chiswick Flyover. I know car drivers don't like it when buses jump the queue but I would argue it's fair enough when the bus is taking dozens of cars off the road at peak time. I don't know if the cost of putting the bus lane in was justified, but it didn't increase car journey times (in fact it reduced them slightly) and it did help make commuter coaches a practical alternative to driving. All I know is the cost of taking the bus lane out once it was there cannot possibly be justified.

I grew up in Newport so know the M4 intimately ... thanks for pointing out the M4 features in England. One of the buildings close to the raised section of the M4 in Chiswick, London was the HQ for the contractor, Turrif, who was working on the North Sea Gas conversions on all the fires and cookers across the UK in 1960's. They made a big mess of the conversions and so every time we passed it my mother would comment on that company!

Took loads of pics and will return when the weather improves. Many thanks for encouraging me to visit a place on my doorstep that I would otherwise have probably missed 👍

[@amazulu3401]

If you ever revisit the history of the M4 Jon, see if you can find out about the massive diversion road that diverted the whole motorway, to motorway standard, back inthe 80s / 90s near the 8/9 Maidenhead junction. I distinctly remember it diverted north in a massive loop into a field before rejoining the main carriageway again, with some very tight exit and entry curves. I cant remember exactly where it was, again pretty sure it was between 10 and 8/9, but I do have a vague recollection of it being something to do with flood management and the construction of a new bridge, but cant find any info about it and goole earth shows no remnants. Carry on the excellent work.

[@ianhelps3749]

The A329(M) is very useful if you live in Bracknell or Wokingham and you want to go to Reading. It's usually quiet and you can do the trip in a few minutes. I remember vaguely that there was an accident during construction of the Winnersh interchange due to a scaffolding collapse and a couple of workers were killed.

[@gavinjamie]

The Curly Wurly bridge is also part of national cycle route 45 and is almost impossible to go down on a bicycle without making a "wheeeee!" noise.

[@georgef822]

Been waiting for this and really enjoyed it. I'm bang in the middle of the M3&M4 near Wokingham. Regarding the M31 5:20, You can leave the M3 at junction 3 and use the A322 that goes directly to the A329m & M4 junction 10 which really serves the same purpose as what this M31 Motorway would have done by the sounds of it. The A322 also goes directly from the A3 as well. It seems to be the go to route for truckers to get from the M3 to M4. Or, you can leave the M3 at junction 6 for Basingstoke and take either the A33 or the A339 which takes you directly the M4 junctions 11 or 13 respectively. Also glad you mentioned the abandoned bridge between junctions 10&11. Was hoping you would.

Lets not kid ourselves a two lane road which runs through Bracknell which is hit by traffic lights every 200m will in anyway do what the M31 would have done for the traffic around Bracknell and more importantly on the M25

The "Curley Whirly Bridge" is for the footpath from the Coate Water park to Chisledon. The Coate Water Reservoir was for the Marlborough branch of the Rail network from Swindon, via Swindon's Old Town Branch. The path is the old rail line route that runs near the ESSO garage on the A346 and along side it towards Marlborough.

Other interesting fact about the M4 (for me at least) is there as several fake trees along it, mainly east of J13. They seem to be radio masts of some sort, but would be interested to find out more about them! Shame it was dark at the end, the walk along the wall Severn Beach is quite nice. Great for mindfulness if you need!

Been living local to, and driving under, the ghostbridge between J10 & J11 for 27 years and never realised it was abandoned. Another random one, right at M4 J12, Theale High Street road was supposed to run through Theale High Street, then tunnel under the M4 and link to Pincents Lane on the other side. It's obvious when looking at the satellite imagery. Even the bridge that crosses over the M4 is named High Street. But the tunnel never materialised... ... which is a shame as IKEA Reading now exists and it would have been an ideal access infrastructure.

The lowest speed limit imposed on a motorway is actually the A57(M) (mancunian way) at 30mph, temporarily brought in february 2022 from 50mph to reduce the high number of accidents. Although it’s only a temporary measure at this moment, it’s likely the new speed limit will remain permanent due to the reduction of collisions 👍🏻

[@MatthewLee8383]

Measure to compensate for the retarded drivers causing crashes. 😒

Was waiting for this one and see what you would find at Junc 14 and 15 as I live in Swindon. Have cycled and ran ( in the loosest sense) up and down the circly worly bridge and Coate Water is one of my favourite spots in the area. Nice drone footage of the restored diving platform

We didnt have the weather for it but Coate water would be great on a sunny day.

[@apacherider7110]

Where you have Junction 8/9, that wasn't there in the 60's and early 70's M4 curved up to the now A404(M) and the M4 stopped at the junction 9A junction. The A404(M) to the A4 roundabout call the Thicket roundabout, name after the National Trust woods nearby. This road was is a new addition many years ago. In the Thicket woods is a road called the Dutch Camp Rd, this is were the Dutch army set up Camp in WW2. I grew up in nearby Cox Green from 1966 when I was 5.

1:10 Re: the speed limit - the Mancunian Way currently has an 18-month temporary 30mph limit with what seems to be the intention of making this permanent next year, although it's classed as the A57(M) so I'm not sure whether you'd count it. It's elevated with no hard shoulder, the same as the Chiswick Flyover, but it has so many entrances and exits in only 2 miles that it's often slower than 30mph anyway.

Smart motorways are a fundamentally good idea. The conversion of hard shoulder to permanent running lane, not so much. On the M1 back in the day, hard shoulder was used as a running lane only when the VSL was at 50 or below. Peak traffic flow seems to happen at a well-observed 50, with laminar flow characteristics.

[@yeknommonkey]

They are not a fundamentally good idea unless you care more about people getting to work 10mins earlier than you do about a few people dying. See how great an idea you think they are when your wife phones you and tells you she’s stopped in lane 1 with your baby in the back of the car and doesn’t know what to do.

[@GuyChapman]

@@yeknommonkey you are confusing smart motorways with all-lane running. Smart motorways includes VSLs, which are an excellent idea because they smooth traffic flow and increase effective capacity at peak times due to laminar vs. turbulent flow. At low speeds, 50 or less, all-lane running is also not a huge issue - remember that dual carriageways have a 70 limit and no hard shoulder. The stupid part is converting the hard shoulder to a permanent running lane even when the limit is 70, and that is not "smart motorways" so much as "stupid government", or rather, government wanting an increase in capacity without going through all that tedious spending-money-to-add-capacity business.

[@danoneill8751]

50mph fastest - true dat... For about 15 years they were upgrading the M3 between bracknell and the m25, I commuted along it for the whole of that time, including 4 or 5 extra trips in the afternoons. It was variously held at 50mph with average speed checks - read VERY well observed. My commute was not just slightly faster, about 5mins faster when they had the 50mph in place, but the consistency was the key... it was ALWAYS the same commute time. The compression and lowdown was at the same place same time, and I remember that there was almost never a crash or other incident to add the typical 9hrs to the commute when that happens. Compare that to the M4 at 70, every 3rd commute (and yes, I've been counting, when you are late to work so often you can't help but keep a tally) some moron crashes and adds hours to the journey in. Every 6th commute in the evening is affected too. I'd take that 50mph average speed check on conjested zones, e.g. where the m4 goes past reading or nears the m25 any day.

Curly Wurly Bridge. Been under it 1,000's of times and never knew. There is also and exit/entrance just north of Castle Combe (j17 to j18) where it was rumoured the Royals could get on and off if needed And RAF Welford used to be supplied by the railway from Newbury. During a rail strike in the 70's the US Base Commander was unable to move bombs. He expected the railway to still move bombs when on strike. When he was told no way, he got the line removed. Gulf war and the B52's out of Fairford were supplied with bombs from this base by road. Right, back to the M4...

[@IceCanine]

I know where you mean. I’ve always wondered what that little road was for. Goes up to the Fosse Way, up to Westonbirt and along to Highgrove. J17 and J18 are my two local junctions.

[@Creative_Devise]

I'm looking forward to a video about the M25 hopefully! Great video as always.

[@arenalife]

Interesting facts for the Welsh Stretch: The only reason the dreaded Brynglas tunnels exist, which have caused great suffering for M4 travelers for decades is because a railway line ran across the hill it goes through, so there could be no cutting. Shortly after it opened they closed the railway line so could have had a cutting after all....... the trackbed is now a local road which runs over the Eastern Portal Bassaleg junction is very dangerous, the one slip road carries both on AND off traffic many fatal accidents here over the years from going the wrong way up the M4...... it's also on a bind brow, oh and a blind corner (yes, on a motorway) No Junction 30, the posh people of North Cardiff in Lisvane put a stop to that filthy nonsense Coryton interchange - the UKs longest motorway roundabout - 1.8 miles around. Interestingly, if you stay in the middle lane and keep going round that'll take you to every turn off - very handy as my sister is scared of it The viaduct bridge after J36 Sarn is an upside down arch shape- very fancy for it's time - most people assume they're just driving at ground level Port Talbot is insane, they basically built a motorway through an urban area, before it was a 50 limit you could leave the motorway at 70mph and within 30 yards be in a residential street going past peoples front doors. One shot slip roads too where you go from the local 30 limit up a ramp and into the motorway traffic. Not as wild now but still pretty hairy. Lots more I've missed I'm sure

M4 Bus lane. A bus lane was put in on the M8 extension from Newbridge to Hermiston Gait but it used the hard shoulder as the bus lane. When I lived in Bath I cycled the A4 in both directions. It was around the time the Prince Charles Bridge was being constructed. I never actually saw it, but I heard it. If I cycled to Wales, I used the Severn Bridge. Its boxed construction meant that the cycle lanes/walkways were outrigged with the bulk of the roadway above you so you got a great view of the estuary westwards and nothing but ruddy great Severn Bridge and car deck almost above you. The times I cycled from Wales, it was dark so I didn't see anything but you could hear the construction going on.

[@bradleyharrisYT]

[@surfblue63]

The elevated part of the M4 brings back memories of the late 1960's when we used to go and visit my nan in Sidcup. Always liked the trip back after dak when you could see the Lucozade sign in all its glory. Pity it was covered up and lost to some new fangled LED advertising board.

[@richardsawyer5428]

[@johnwinters4201]

The M4 bus lane was perfectly sensible and reduced congestion. The point is, once you get to the elevated section there are only two lanes and there's no way that can be changed. By adding the bus lane, which started at the previous junction on the M4, you got rid of any need for traffic to merge. One lane peeled off at the junction and two lanes then continued on into the elevated section. By getting rid of that horrible merge at the start of the elevated section, flow was significantly improved. The second best option would have been simply to get rid of the third lane in that section entirely. Sadly, far too many drivers with the IQ of a Clarkson don't appreciate how fluid flow works and so it suffered from an awful lot of irrational opposition, which meant it was eventually removed.

[@Johnketes54]

As i said recently if we remove buses from privatisation and hand them back to councils and subsidise them bringing the fair right down,Forget about profit and running cost work on reducing traffic and increasing flow but it has a serious flaw it doesn't make MONEY,That what everyone worships their diety MONEY even temple's called banks,And ofcourse when the bank mess up the tax payer bails them out and then give themselves big wads of taxpayers money called bonuses

Not a motorway, but there's a slightly less curly wurly bridge on the A92, between the Chapel interchange, and Kirkcaldy East roundabout. It links the Dunniker Estate to a public right of way on the other side of the A92.
