This source says there will be "semi" motorway between Jönköping and Ulricehamn on route 40. I suppose that means 2+1 road will remain.

Is that correct?

I think only improving the intersections will be done, only further west will there be built a new motorway.

We also have some motorways who can be used as emergency airstrips during a war.

If we talking about the real motorways in Sweden, not the 2+1 roads.

Many of the motorways here in Sweden are quite basic. There are parts there are very few exits, no petrol station for a very long way and the motorways in Sweden don’t have any emergency telephones. So there is some parts were you can drive a long way without anything.

I would say the rumours are true. In my hometown there's an airforce museum, and they have a flight simulator where among other things, you can try to land a JAS 39 Gripen on this road which is located just a few kilometers away. Here's a picture of the road:


So yes, some of these roads could be used as emergency airstrips during a war.

I was quite surprised about that too. Swedish motorways in average don’t look like as nice as motorways in central Europe:

- I noticed sometimes there are no hard shoulders.

- The fence in the median is sometimes wired instead of concrete or steel. Anyway how safe are wired fences?

- There are and will remain “wholes” in the motorway connections, for example on E4 between Helsingborg and Gävle or better Jönköping there is half motorway (2+1) Dörarp - Kanna 31,1 km, another example road 40 between Jönköping and Göteborg, there is and will remain 2+1 Jönköping – Ulricehamn 43,8 km.

Sweden is a big country for nine million people and has low density.

Is reason for all that (no hard shoulders, wholes, no telephones, no petrol stations, few exits….) low density and AADT?

Very unsafe. They were outlawed completely in Denmark more than 10 years ago.

The main problem was that cars would get entangled in the wire, and would make rescue operations take longer.

Another problem was that the wire would snap under high-energy impacts, and could result in the involved cars to hit on-coming traffic.

They are very safe since they are flexible, you bounce back instead of being crushed like you would if they where made out of concrete.

Yes, and it helps with some of the story about the changing views on wired fences in Denmark.

More recently - 2009: It seems motorcyclists still don't like them:

Well, they seem to work just fine for the cars:

..but I see why motorcyclist hate them. In my opinion they are OK only in the median.

I guess this kind of scenario could happen if the wire breaks?:

And this kind of scenario would happen if it doesn't brake (but act as some kind of "elastic" wire as shown on video)?:

As far as I looked couple of 2+1 examples on googlemaps streetview, it looks like it's from one intersection till other. So maybe about 1,5 km in average.

You mean how many km of fence of this kind is there? Well wikipedia says there are more than 1.000 km of 2+1 roads in Sweden, without motorways.

Sweden also has 1+1 roads with wired fences.
Not only 2+1

They're getting more common. But it's only 1+1 for like 1,5 km, then it's 2+1 or 2+2 again. A good example is the new E18 between Karlskoga and Lekhyttan that will have sections with 1+1.

Yep, another example is 800m on Uppsala western bypass.
