This stretch of London's M25 orbital has 6 lanes each way:

Only a couple of km. There is a stretch of about 20km that is 5+5 now though, and about 100km of 4+4. In the next few years the whole of the M25 (200km) will become at least 4+4.

the reason they "seperate" freeway lanes (by creating a trunk section and an outer section) is to make the freeway more efficient. After approx 5-6 lanes the efficiency of each new lane decreases due to people having to navigate (or should i say weave) thru so many lanes just to exit.

there are plans to build such a freeway config in san diego on the 5, but i know little of the project.

its depressing to see big freeways even in europe. sigh

I agree. I also think it would be useful to have US freeways separated in the same manner European and South American motorways are. For instance, vacating at least two left-most lanes only for those "tourists" who are passing through. This way, local drivers will not be able to use those lanes and conjest them during rush hour. I know that it would make a lot of sense in case of I-5 and I-80 that both run through Sacramento.

The A4 motorway in Paris Southwest is 2x5 lanes during a dozen kilometers:




And just like what we can find in Madrid, the A6 motorway in Southern Paris is 4x3 lanes also during several kilometers:



Afterwards, we can find some small portions on the A1, the A3 or the A86 which are 2x5 lanes, but they aren't generally very long. That's mostly the case when several highways merge. I guess we can find that kind of small portions everywhere in Europe.

Here is an example of what I mention that we can find on the A1 motorway in Northern Paris:

If this counts, the A5 south of the Frankfurter Kreuz should count too:



Also the A3 east of the Frankfurter Kreuz.
But i believe there are sections of this kind all over europe...

But north of the Frankfurter Kreuz, its planned to upgrade the A5 from 2x4 to 2x6 lanes. But they will be divided: either 2+3+3+2 (like A12 near Utrecht) or 3+3+3+3 or 2+4+4+2.

The reason for dividing motorways isnt that it would be forbidden to have more than 4 lanes each direction, but to divide trunk traffic from local traffic. so the inner lanes normally have fewer exits than the outer lanes.

There aren't any in Spain either, and there I'm sure it's not allowed to build more than 4 lanes in the trunk section.
Although you can have things like this:


But the basic section of this freeway (Madrid's M30) is 3+3+3+3 I think... 4 lanes at max, for each carrigeway. Not 6+6 for example, because that wouldn't be allowed.

WRONG! Theres are some freeways with more than 4 lanes wide. For example, A3 (Porto - Braga Highway) has 5 lanes before the conecction to A4 (Porto - Amarante Highway)

Not 5 trunk lanes... There are some sections near some junctions which may have more than 4, but some are weaving lanes, etc... That doesn't count, as I've said.

Man you guys have awesome freeways. I'm from Brisbane, Australia and the only BIG highway we have is the Pacific, (M1) which runs from Brisbane to the Goast Coast and is 4+4. The Ipswich Motorway (which is the WORST road atm) is being upgraded to 3+3, and should be completed by 2011.

I wish we could have bigger ones. But oh well. Thanks for the pics everyone!

PD: my english finish here... the spanish standand suggests to build service lanes on the sides if it's necesary more than 4 lanes per sense.

I don't think those count, it's not a collector-express setup, but simple collector-distributor lanes from an interchange.
