it's the main highway of Italy, there are no major difference in traffic. There is traffic for the entire lenght. Depends on the day, the period and other factors which section gets clogged but in general outside Milan the traffic is quite homegeneous

Here is a map of Germany's current Autobahn system

red = 2x2 lane
violet = 3x3 lane
dark violet = 4x4 lane

I have discovered only five regular 4x4 lane stretches in that map:

A5: from intersection with A648 (in Frankfurt) until intersection with A67 (Darmstadt). A short stretch of the main lanes is only 3x3 at Frankfurter Kreuz (double intersection with A3 and national road B43). Alltogether ca. 28 km

A3: from intersection with A661 (south of Frankfurt) until intersection with A5. Ca. 7,5 km

A9: from intersection with A92 until intersection with A99 (north of Munich). Ca. 10 km

Another few km on the A7 north and south of the Elbe tunnel in Hamburg and a few km on the A46 at the intersection with the A3 near Düsseldorf.

Terminology mixup

Some people say 3x3, others say 2x3, others say 3+3 others say "6".

I see...so it's not very common in Germany. Probably because you have a very good grid of highways which distribute more evenly the traffic

Thanks to recent reconstruction and widening, the Tri-State Tollway from near the Illinois-Wisconsin state line to where I-80/94 meets I-65 in northwest Indiana is now 8 lanes each way for the entire length. That's about 80 or 90 miles. Long term plans call for adding an additional lane each way from the state line to Milwaukee, which would add about 40 miles to that total.

I'm not sure if you count all of that because the freeway/tollway changes numbers from I-94 to I-294, but it's one continuous road where the dominant flow of traffic stays on that particular route, regardless of name change.

Here in England there aren't many roads with more than 6 lanes. The M56 from the Wilmslow Road junction to Princess Parkway is 8 lanes. There are also parts of the M25 which are pretty big!

In Sweden, the only 4+4 road I know of is Essingeleden, the urban motorway in Stockholm. Google Street View

When using a "multiple x" it is normal to put the number of carriageways to left of the x, and the number of lanes per carriageway right of the x.
2x3 = 3+3

Systems with more than two carriageways are often described by the number of lanes per carriagway, seperated by an indent.
3x3 = 3-3-3

Caltrans has plans to upgrade this gap in the future, so it will eventually be 221 miles.

Anyway it will be more than 120 km 4*4, it's already pretty good
You forgot to add upcoming widening of A4 between Bergamo - Brescia or I'm wrong? And also isn't A4 planned to be widened to 2x4 up to Novara? This would make pretty long 2x4 section (about 130 km).

It's in my first post.

I think Bergamo-Brescia is not so imminent. The 4th lane towards Novara will be in reality up to Marcallo Mesero (highway to MXP) and not Novara

He just listed the stretches scheduled in autostrade spa web site

Actually there are even other stretches scheduled for a widening to a 2X4:
S. Cesareo - Frosinone on A1 (47,9 km)
Ravenna junction - Bologna S. lazzaro on A14 (34,1 km)

Then there are other 'rumors' for widening to 2X4 Torino bypass, Tangenziale Est and Ovest in Milan (what could make the total lenght of a continuos 2X4 maximum run even longer) and maybe in some other stretches (I'd personally bring the last part of A1 from Caserta to Napoli from 2x3 to 2x4 -if I'm not wrong a very little stretch is 2X4 yet- but I don't know if there is some project on it)

I think the widest in Canada is the 401 at 18 lanes for a few kilometres before tapering off just 12.

18


12



The 111 is the widest in Atlantic Canada, where I live, with 12 lanes for only a dozen metres or so before becoming 10, 8, 6 and down to 4.

12, 10


8


6 (2x4, 4 southbound)



This is the 111 in its entirety, driving its northbound route.

They're actually already working on widening the Wisconsin portion of I-94 up to Milwaukee.

When it's finished it will create 130 miles of 2x4 highway from Interstate 65 in Indiana, up through the Tri-State/I-94 corridor past Chicago and up to Milwaukee.

As you stated though, it's actually two interstates, I-94 and I-294 - but if you're driving this route, it acts as one through road - it just happens to change names as it goes through Chicago.
