E22 Malmö - Kristianstad

A new segment of E22 will open on May 26 - with restrictions. 110 km/h will be allowed from 19 June onwards. It's the Rolsberga - Fogdarp section.

I have a question about road safety improvements in Sweden, concerning 2+1 roads upgrade from basic 2 lanes undivided main roads.
Have they really improved road safety and reduced fatalities in your country, and moreover, what was the economical cost to built them?
A study showing that would be great.
I need an answer for the Polish forum .

I googled for "2+1 väg kostnad" and got this result: http://www.diva-portal.org/smash/get...FULLTEXT01.pdf

It's from 2002, so a little dated, but it says in the summary that the cost varies from 600 - 2500 SEK per meter. Which is approximately € 66,000 - € 275,000 per kilometer for restriping and adding a median cable barrier. It very likely does not include any paving (or widening).

Are there any online maps that differentiate between 2+1 and 1+1 roads? Since 2+1's are so famous in Sweden, I'd like to see how extensive they are. I thought ViaMichelin might, since their printed maps are very detailed about the number of lanes, but their online maps are much simplified and don't give this information. (I wish Google maps was better about this, but they don't even differentiate non-motorway 2+2 divided roads from 1+1 roads.)

They are so stupid! Only one lane, my God how much can that cost? Sadly this infection has been caught also by Finnish road planners...

Now you have to be very careful...

Most of the Swedish 2+1 roads are not a result from a major upgrade. Instead, they took the existing 2.75+3.75+3.75+2.75=13.00 m roads, repaved them to hide the road markings, and converted them to 1.00+3.75+3.50+3.75+1.00 = 13.00 m roads by doing not much more than adding the middle barrier. That is why they were able to open the first few thousands kilometres so quickly. The cost per kilometre was about 20-25% of upgrading a 10.00 m wide 1+1 road to 15.75 m 2+1 road in Finland (in similar climate conditions).

The new 2+1 roads are somewhat wider, usually 14.00 metres. Comparing the cost of newbuilds to the initial quick and dirty solution might lead to misleading conclusions.

To summarise: If you happen to have wide enough 1+1 roads, converting them to 2+1 roads is rather cheap. Everything else is expensive.

I found a publication from 2009 evaluating the 2+1 roads, available here. It's in Swedish (although with an English summary).

As far as I know, there are no maps that do this. However, Trafikverket has maps with administrative data for the roads. If you go here and select "Väguppgifter" from the box to the right and then "Vägtyp", it should show different classifications of the roads, with those saying "mötesfri" probably being 2+1 or 1+1. You might have to zoom in a bit for the roads to be colourised. The site seems a bit shaky to use though, I can't get it to show the data at the moment. :\

I would say that up to 90 % of all national roads are at least 2+1 at some sections, usually where there is a hilly part, to make it easier for overtaking heavy vehicles.


In my area: Östergötland there is only the road 23 which is not a national 2+1 road but 1+1 with barrier (no overtaking possible) at some places.


If you use google maps just go street view and you will se what roads are 2+1 or not.


Uphill at the 34 east of Borensberg. Otherwise a 1+1 road.


The 35 is mainly a 1+1 road but at some uphill sections it has 2+1 lanes.



1+1 with barrier on the 23 south of Linköping


Secondary road 636 (unmarked lowest category) with 2+1 lanes and 100km/h speed limit.
Previous trunkroad and parallell road to the E4 motorway


National road 55 is 2+1 all the way between Norrköping and Katrineholm.


Road 50 has 2+1 lanes north of Motala.

Thanks! I will take a look at it.

But why do they spend money on crap instead of building a narrow 2+2-lane-road??

Whereas Germany built thousands of kilometers of Autobahns from the 50´s to the 80´s, Sweden only built a couple of hundred km. On the other hand, some 5000km of 13m wide highways were built. They proved to be really dangerous, installing a median barrier for 600 SEK/m (without repaving) or 2500 SEK/m (including repaving and moving the road ridge) isn´t crap. Many of these roads don´t have very high traffic volumes.

The AADT doesn't warrant that on most roads, and 2+1 is cheaper.

Var: Under broarna vid trafikplats Rinkeby

Du kan ta dig till invigningsplatsen genom att promenera eller cykla. Invigningsbuss avgår från Rinkeby Torg kl. 13.30, 13.45 och 14.00 samt går tillbaka efter invigningens slut. Det går inte att ta sig till invigningsplatsen med bil.

Från klockan 14.00 bjuder vi på kaffe, saft och bulle.

Invigningstalare är infrastrukturminister Catharina Elmsäter-Svärd. Programvärdar är Alexandra Pascalidou, journalist/författare och Thomas Andersson, VD för Kista Science City. För underhållningen svarar Kulturskolan i Spånga-Tensta/Rinkeby-Kista.

Välkommen!
The section I bolded? "You can't get to the opening ceremony site by car." For a motorway opening.

Well, of course. The road leading to that place is closed, isn't it so? Going back home by car shouldn't be a problem though

Is it much cheaper? Considering Swedish geography, I wonder why they don't do 2x2, with one 2 lane carriageway through the forest, and a wide forest median before the other carriagway like often in the USA (I mean like 20 or 50 m of trees between each direction) it uses lots of land, but I would think the land mostly free?

Why waste space with a wide median anyway. It would require more expensive bridges and underpasses aswell.

Why would they do?

The land is far from being free. Do not forget the forest=timber=money rule in effect in the Nordic countries. According to the statistics of the Swedish Forest Agency, the price the forest land was about 56,000 SEK/hectar in average in 2010, varying from 34,000 in the north and 84,000 in the south. Converting to euros and taking some inflation into account, we get approximate prices 7000, 4300 and 10500 EUR respectively. If the road in question would be 12-50-12 meters wide, that would need about a 95 metres wide opening, thus 9.5 hectares per one kilometre of road. The cost of land only would be 67,000 EUR per km in average, varying from 40,000 to 100,000.

The cost to build a road correlates rather well to the area of the road. Why to double the cost for no reason?
