Well, you stated 'In about 99.99% of the cases preheating is not about making the engine to start but about comfort and saving the car. It saves time, effort (and the window glass) if there is no need to scrape the windows.'

Situations like these are definitely not limited to Scandinavia, but occur on a regular basis in most of Central Europe as well (not to mention Eastern Europe). Winter may be colder in Poland than Norway's coastal cities, where most of the population lives. I suppose that plugging in cars for heating may be more common in Sweden and Finland than most of Norway?

Although already briefly mentioned, I would just emphasize that starting with a cold engine has a huge impact on the emissions, in particular CO, HCs, and NOx, and also the fuel consumption is increasing. In total, the emissions are said to increase by 70% it is claimed in this article (not sure how that was calculated) http://www.tu.no/artikler/trodde-du-...m-igjen/276271. Personally, I have never experience a non-start that has been caused by cold weather alone.

The higher prevalence of engine heaters in the Nordics compared with countries further south in Europe is probably due a mixture of a factors such as a longer cold season, a larger fraction of private parking compared with street /public parking and a long term public focus on the negative effects of cold-starts on the car and the environment.

Many mountain roads are closed due to the upcoming windstorm. They advise people not to travel today.

Norðadalsskarð station on the Faroe Islands reported a 283 km/h wind gust this morning.

E39 Sandnes

The new span of the Kvelluren Bridge of E39 in Sandnes (south of Stavanger) opens to traffic tomorrow. The old span will be renovated afterwards.

I always wondered why it was never built with twin tunnels and to motorway standard when they refitted the road, it's always been busy whenever i've driven it.

How much does the fact Norway was under a tall ice sheet until the 'recent' geological past make soil better or worse for tunnel excavation than mountains creating by continental derive (Alps, Pyrenees) or by much older erosion (Iberian highlands)?

Proposal for new N100 Road design manuals on hearing. One change is that all motorways now will be 23 m (not 20 m and 23 m), but alignment demands will on some areas be more liberal.

I think it is positive if we get rid of the substandard motorway class. Unfortunately, this change is not likely to be applied for projects under various stages of planning today, a nye d IMO, all motorways should be planned for at least 120.

I am not a geologist, but I believe the main effect is that solid (Igneous) rock is fairly close to the surface in most of Norway, which makes tunnel construction easier. Especially in the lowlands of central ("Trøndelag") and eastern Norway there is one complication, however. Since the ice withdrew, the land has, and still is, rising, meaning that former seabottom with marine clay has surfaced. This clay can be very unstable once the salt is washed out.

They call that the post-glacial rebound. Apparently it is particularly pronounced in Finland.

Sure. It is "maannousu", literally "raise of land".

It does not have a major impact on road construction. But the marine fairways need to be upraded regularly (every 50-100 years). In addition it causes interesting legal disputes at the shoreline.

Because the rise in one metre per century in the NW and about zero in the SE, the area of the country is constantly tilting more and more. he water pressure against to the SE lakeshores increase, and the big lakes might find a new outlet toward the sea. That would be a major nature hazard. Such a phenomena has happened a few times during the last 10000 years, latest in about 4000 B.C.

Happy new year to everyone. Currently, Norway, Sweden and the West Europe are one year behind Finland.

Fv. 655 Norangsdalen

Some photos of Fylkesvei 655 through scenic Norangsdalen (location). It is one valley west of the better known Geirangerfjord.

1. It starts off with an error, this is not Fv. 60, but Fv. 655. This sign is located just after the Fv. 60 junction, at the start of Fv. 655.

Are there plans to close the gap (bridge/tunnel) of E5 on Sognefjord?

Do you mean highway 5 (rv. 5)? If so, it`s been mentioned in the KVU for main roads east-west, but afaik no real studies of a possible structure. Rv. 5 is seen as an alternative faster road between Oslo and Ålesund than E6/E136 if such a bridge is realized together with a general lift of standard on the more of rv. 5, rv. 7, rv. 52 and E39.

I would guess such a bridge is far into the future, as the current ferry-crossing with connecting roads and tunnels is quite new (1995) an holds a high standard for the route today.

Alright. I though the tunnels there were like a prelude to future works on a bridge maybe. I don't know how the tunnels look internally,

Another question: how much traffic does Rv 50 have between Aurlandsvangen and Hagafoss? It looks a strange road: it has a rather complex hairpin alignment with tunnels, three medium-length tunnels, and a quite wide alignment in the center, but it is narrow (1.5 road) at both ends of the plateau it traverses.

It is Fv50 nowadays. The AADT is 300 but that is not the whole truth: Because it is a tourist road, the volumes vary a lot: from 100 in Nov-Jan to 800 in the summer.

The road was originally built as an access road to the construction site of the Aurland power plant system. That explains some oddities. A very nice scenic road.

I thought the road was closed during winter. Which of the major links in the region are close seasonally? Just Rv53?

Are all these tolled tunnels and bridges financed in such a way that toll collection is temporary (until construction costs are paid only)?

No, it is not closed. (Right now it is, for technical problems whatever it means. A broken snowplougher perhaps.) The local admin wants to close it and the Tyin-Årdal part of the Fv53, but the cabin owners and other locals resist. For Fv50, the energy company E-CO is also "concerned", because they have six power plants in the area, with the total production capacity of about 1000 MW.

The only major links nearby to be closed for winter are Fv51 and Fv55 (Valdresflya and Sognefjellet), I believe. Such tourist roads as Fv13 Gaularfjell are not major ones. Of course, many roads are closed temporarily, or the convoy mode is turned on.

About so. The tolls cover a predefined percentage of the construction cost, the interest, and the cost to collect. Sometimes, the tolls are reintroduced, or the period is extended, because of new projects. In some cases, the toll is collected as an extra fee on the ferries. The toll rings around towns are permanent ones.
