Evidently Statens Vegvesen maintains 134 timber bridges, 79 of them for pedestrians and cyclists and 55 of them for general traffic.

The collapsed bridge has a 45 meter span and is 5 meters wide, with a single lane. There are six such bridges along the E6 upgrade project between Ringebu and Otta.

What is the tallest rock cut (for a road) in Norway?

Perhaps not the tallest, but maybe the straightest (and most viewed?).

The bridge collapse on E6 was due to a design error. An error in calculation occurred, it was supposed to be designed for a load capacity of 65 tons, but in reality it was a third of that. The logging truck weighed 31 tons and thus the bridge collapsed.

Ehhhh...?

Even if they put streetlights to every kilometer of motorway, in the country, that would make about one third only of the total length of public roads and streets in Oslo. I believe most of the streets in Oslo have streetlights. Never heard that the cities in Norway suffer severely from the cost of streetlights. Compared to that cost, the illumination of motorways is insignificant.

Strange that no alarm bells rang, but there are still relatively few massive wood bridges of this type.

I guess the most viewed ones are on E6 (eg https://goo.gl/maps/Z87v56SggxJ2) or E18 around Oslo.

They are all over the place, but nobody seems to have bothered to keep any type of statistics on them. For the older ones it is also sometimes tricky for a lay man to tell where the cut stops and natural cliff starts.

Nowadays new rock cuts are of course often quite contriversal. However, they are often gems for geologists:


What is a bit ironic, is that the same type of people that fight new rock cuts actually have preserved existing ones as natural reserves since some types of threatened flora seem to thrive there.

These glacial-pressed granitic blocs look so weird.

These rocks are formed deep down at high temperature. Not sure how important glaciers are, except perhaps for uncovering them.

That type of rock is formed deeeeeeeeeeeep underground under lots of heat and pressure. Glaciers are unimportant in their formation. Glacial formations like errata and moraines are more landform features than geologic features in individual rocks.

The strategy for fjord-crossings on E39 will be Rogfast first and then mainly move to what gives surplus.

Hordfast 2nd?
Even with a cost of 39 billion nok according road authorities Hordfast comes out with a surplus for society (samfunnsøkonomisk lønnsomt på englesk? ) wich is good news.

In the Bergen area it looks likes the upgrade of Bergen-Voss (road and rail) will come first.
Jubel i Bergen og i Voss for satsingen på Bergensbanen

Also Ringeriksbanen (rail Hønefoss-Oslo on Bergensbanen) is prioritized with a early start.

The whole document from with plans from transport authorities can be found here.

Well... Everyone ever been involved with such cost-benefit models (including myself) knows how to manipulate them. Just add a number of less significant rows, and carefully adjust the weights and scores, and voilà, the model gives exactly the same result as you wanted.

The result shown in the report is quite close to zero. Most probably, it would be very easy to get a negative final score, too.

The interpretation of the statement "beneficial in the national economic dimension" is easy: Those who gain the benefits are not the same people as those who pay the project.

(I am sorry about my lightweight cynicism.)

The same applies to traffic models. Just increase the resistance on some links and you can get what you want.

This is also a factor with toll roads. The traffic demand for a tolled facility is often too optimistic, especially if reasonable untolled alternatives are available. When comparing toll roads to untolled roads, economic models incorporate all expenses related to driving (such as reduced maintenance cost when a toll road results in shorter driving distances) while most consumers only take the out-of-pocket cost into account, such as tolls and fuel expenses, and to a lesser extent; time (time is valued different from user to user). The perceived benefit of paying tolls to improve travel time, distance or reliability is different from the actual benefit.

Anyway it's an indication that the road authorities wants it built, and i'm sure it will happen eventually. After Rogafast is finished there will be more pressure to get it done.

The road is about 60km so it's not that expensive compared to other projects pr.km, like E39 Bergen-Os wich costs 6,5 billion for 13 km.

Here is the motorway plan:

E6 Gudbrandsdalen

The last concrete of the largest bridge of the E6 Frya - Sjoa project has been cast. This is an extradosed bridge, it will open to traffic in December.

Today the company which has taken over responsibility of construct a lot of the new motorways in Norway from the road administration released it`s first schedule of which sections that`s prioritized:

* E18 Tvedestrand-Arendal, 23km, will probably commence later this year. Preparatory works commenced last fall.

* E18 Rugtvedt-Dørdal, 17km, is scheduled to commence early next year.

* E6 Kolomoen-Moelv, 43 km, is scheduled to commence early next year. Hope is to start during first quarter of 2017.

The following stretches (from 2018 at earliest) will be E18 from Kristiansand to Vigeland, near Lindesnes, E6 through Trønderlag and E18 Langangen-Dørdal.
