The powers that be have known about the state of the elevated section of the M4 for more than 20 years. What a wonderful advertisement for the country just as we start the biggest sporting event for 50 years. Personall we are not going within 100 miles of london for the next couple of months. Our neighbours have also cancelled their visit, and none of us will use heathrow at all anymore, what a shambles the last few governments has made of our infrastructure.

They didn't know about the cracked steel that they've just discovered - while carrying out other rectification work.

We expect politicians to foresee the future but in this case the engineers don't have X-ray vision !!

Beg to differ, there have been plenty of reports about the condition of the elevated section, There has always been a wait and see attitude because of the sheer mess it would cause to replace it, especially as now it is lined with office buildings they cannot tunnel under. in the new civil engineer online report dated 28 september 2007 Have known of problems since the 1990's.

Well, sticks and stones, the other advantage of living at the other end of the M4 is that Council tax is £900 ish for our 3 bed semi instead of £3000 in watford. Nice market town, no parking problems, ok no buses at night, but clean quiet place to live, no hassle parking at work, (free) can walk anyway, and people have the time to talk and say hello.

My original point was about the elevated section of the M4, but can anyone say what will happen when it has to be shut for 2 years while it is rebuilt. obviously the A4 and a lot of surrounding roads are going to be shut. God help you with your commuting then!

some of us are fortunate and spend nothing on commuting or parking. If you are switched on, know the controlled hours, use a cycle when solo , you can avoid paying for parking altogether. Have not paid Congestion charge in over 3 years, no need to go there.

'Er indoors commutes 10 stops by tube into town daily - £131 a month. 5 bedroom house C Tax in middle suburbia £2300 pa. Not cheap but not £3k and not Watford . Plenty of well stocked 24 hour groceries within 5 mins walk, and a pharmacy open late 7 days a week .

Motorprop, i admire your enthusiasm for city hell, you're very welcome to it too, you couldn't pay me enough to live in a city, too many city dwellers.

Doing rather nicely out here in the sticks though thankyou, never need to venture out of our abode or quiet garden for peace and quiet, and the salary, which is well above city based jobs in my industry does go an awful long way.

Enjoy the Zil lanes and the anti aircraft batteries on the roof won't you..:-)

Apart from the manure slinging. (plenty of it out here) Has anyone got the faintest idea about what will happen when the elevated section needs to be torn down to rebuild?

In my life, have lived in london twice, noisy, but best entertaiment/nightlife in the world, and actually very safe, New york, just noisy, abu dhabi, just noisy, 12 years in geneva noisy and damned expensive and now not very safe at all! and finally west wales, where if you can't understand what the locals are saying it's probably polish. (just joking now!)

transport - M4 closed junctions 3 to 1 - gordonbennet

Seriously ORB i don't know, but i expect more major overpasses like this to become unsafe as time goes on, it'll be fun when they condemn the elevated section of the M6 as will no doubt happen in due course.

Some 25 or more years ago when the experts were pushing for increased truck weights, to comply with the EU masterstate demands, to go up from 32t max to 38t at the time, they assured us that with more axles the heavier lorries would be kinder to the roads, the way they went on about it you'd think a 5 axle truck just gave the road a gentle massage and a kiss goodnight.

Well, we're up to 44tons on 6 axles, and in most cases those axles are in 2 groups of 3 and only rare trailers have a steering axle...the three trailer axles are usually 8 ton max each so in practice a properly loaded 44 tonner will drag round three axle trailer combinations at around 23tons and those three axles only want to go in a straight line.

You only have to turn a truck hard and watch the rubber left on the road t see what forces are being exterted, look at roundabouts near industrial areas to see the battering the road endures.

Goodness knows how the current quite old overpasses have coped with the relentless battering of such weights day in day out for all these years.

Us old truck drivers never wanted the weights increased by the way, 32 tons was plenty, in most cases allowing a payload of 21/22 tons, now we are at 44 tons gross and the payload is around 28/29 tons., hardly worth it IMO.

I'm not a civil engineer but I've seen photographs of damaged or degraded concrete beams as used in these structures.

Whilst I fully accept the points made above concerning loading, the images I see look as though the damage is due more to structural deterioration than to overloading. It's inconceivable that structural safety margins would be appreciably eroded by incresing axle weights.

Have they been using ordinary road salt on these structures in the Winter time?

659.

Well, truck drivers would say that, wouldn't they! Less weight=more trucks=more demand for drivers.

44 tonnes is nothing. The tractor units have 500+hp these days can easily pull 60+ tonnes. The Aussies routinely pull over 100 tonnes, and, unlike European mincers, no messing around with synchromesh; they still drive properly-as do the Americans. :)

Since the tractor unit+ trailor weighs in at around 15 tonnes, upping the gross weight leads to a useful increase in payload with a corrosponding decrease in fleet fuel consumption and traffic congestion.

''44 tonnes is nothing''

It is when the roads were built for 32 tons maximum and a volume of movements to suit the natural population.

Just been on the London news - M4 wont now be re-opening tomorrow. And they gave no indication of how long this delay might be.

Heathrow is Europe's busiest airport, serving one of the busiest cities in the world. Yet, somehow, the main artery between the two is allowed to fall into dangerous ruin.

What baffles me is why no one body, or person, is being held to account for this. The pervading attitude is almost symapthetic. Perhaps we, as a nation, are worn out with all the scandal and incompetence of the last three years?

Much like the M4!

transport - M4 closed junctions 3 to 1 - gordonbennet

Not just the last three years Sulphur Man, we've learned over our entire lives to accept that the country is mismanaged by imbeciles, every 5 years we replace a bunch of misfit drones with exactly the same.

You'd think by now that the electorate would have learned, instead of which they go and do exactly the same again and put another bunch of no hope clowns in charge, you really couldn't make it up.

Road wise, even as the construction crews were making the M6/M1/A14 junction, none of us as we passed could believe that such a major trunk junction (thats killed and maimed many) would filter down into a single lane as it passes under the M1.

We're conditioned to mismanagement, misappropriation of funds, grand theft, waste of money on a biblical scale and by golden handshakes for incompetents best seen the back of, and anyone who stood up and objected whilst the above went on was attacked from all sides, branded as at least one version of 'ist or several.

But if the extra weight is distributed over a greater number of axles then the total damage to the road substructure should be less with heavier lorries because there would be fewer of them.

But if the extra weight is distributed over a greater number of axles then the total damage to the road substructure should be less with heavier lorries because there would be fewer of them.

I see your point, but if you get 10 trucks passing over a section of bridge for example then the weight of those vehicles alone has increased by 120 tons, not forgetting just how much heavier all vehicles including cars have become.

You only have to look at road undulations to see the devastating effect that trucks have.

Travel North on the A34 just past the Oxford junction, by the service area , you will find as in many places in the country a severe undulation in the road, A43 past Silverstone is similar in several points both ways. This Oxford bump is getting worse, there are constant black marks where the wheels are momentarily leaving the ground and lightly skidding as they land again, obviously as things are the damage is accelerating....this is happening at thousands of points in the road network hundreds of times every hour as the constant battering goes unabated.

You can see the effects of the much vaunted air suspension too, the similar points where recoil occurs, some distance after the bump, where the bouncing fully loaded trailer is at full descent for each of its several recoils, would be interesting to measure how much extra weight is imposed at that point.

By the way, few proper lorry drivers wanted synchro or auto boxes here either, the use of which has allowed too many non drivers on the job..:-)

Anyone would think that the powers that be don't want tourists and business to come to London, the absolute shambles at Heathrow, (There are now extra security guards and police to stop people from "charging" the empty passport control gates! )

Would it not be cost effective to have more immigration officers on duty for the same money? all this means that we now book easyjet to europe and fly onward to avoid heathrow, we can now get to see family in Amman with easyjet, so why pay more to be held hostage at heathrow.

As for the hotels in london, some friends asked me to book ahotel for them, and when i inspected the hotel in sussex gardens just off the edgeware road, i said i would not put my dog in there. AND it was expensive. I understand that millions of people are stuck there, and do feel sorry for them. While our modern politicians are only in it for what they can line their pockets with, there is no hope for this country. In our last two visits in london we have returned food in restaurants saying it was not fit to eat, and paid for the drinks and left!

Anyone remember how long it took the city of LA to rebuild the I-10 freeway destroyed by the earthquake in 1992? Was it 6 or 10 weeks? (please help by correcting me if I'm wrong).

Remember, this was a 6 or 8 lane highway in a earthquake damaged city, not a 4 lane road (OK 6 lanes at one end) in of one of the world's greatest cities (a city that got the Olympic stadium etc built on time).

Best to start the planning now, then the job could be completed by xmas. If they have any sense this road could be built wider so to increase capacity, at least outbound, or even double decked.
transport - M4 closed junctions 3 to 1 - motorprop

That's because in earthquake zones they build them to be rebuildable quickly. Quick n cheap.

How long is it taking to build Ground Zero ?

transport - M4 closed junctions 3 to 1 - Smileyman
I do not consider comparison with Ground Zero to be appropriate, 3,000 + people died there and what is being built has a historical aspect in their memory.

The freeway in LA is a major road artery like the M4, and anyway, even though the first road was destroyed by an earthquake, no-one had forecast the timing of this event, it might not have happended for 20 or 50 or 100 years. So the ability to re-build it within weeks is an appropriate comparison to what is (probably) needed for the elevated M4.
transport - M4 closed junctions 3 to 1 - motorprop

you are right to an extent - Ground Zero was cleared within a year. What has happened since ?

M4 - Always easier to demolish ( that was quick and free over there ) and re-build new than repair around an existing, damaged facility. They have lots of cheap land in comparison. We have tight residential areas to consider and well oiled objection procedures. Each email by a lodging tenant gets considered

British engineers highly sought after in major construction projects worldwide.

>> Each email by a lodging tenant gets considered

Two documentaraies I have seen come to mind.

The first was on high-speed rail and the interview was with an engineer from the French rail board (not SNCF, they do trains, but their equivalent of Network Rail.....yes, they have the same split, despite what you see in the press). He was asked how they'd managed to build out their high speed network so rapidly and with such great success. The answer was simple. There'd been no planning or appeals process until two years previously. They were at that time attempting to build a line to the west and this had been mired in an interminable and phenomenally costly planning/enquiry/impact process with no end in sight for, er, two years.

The second was on the Hoover dam. They got top people from the various branches of engineering to study the project and comment. The geologists said it was in the right place. The dam engineers said it had the right design. The power people said that side had been got spot on too. The construction types said that it would take rather longer than the four years taken at the time to build these days, as the injuries and deaths would be considered unacceptable and more care would have to be taken, but it was still a viable project. The bean-counter said that in real terms it would be somewhat more expensive, due to the additional build time, but still show a sensible return on investment.

Then the environmental impact bloke laughed his socks off. He said that the environmental impact study would take ten years. It would also be pointless, as it would never be approved in a month of Sundays.

So that's two major pieces of infrastruture, both often quoted as shining examples of great projects of major public worth, both of which would be strangled by red tape if they were being started now.
