It can make driving in Austria a real ugly experience. The most beautiful mountain sceneries being obstructed by the most hideous concrete noise barrier! At least in Switzerland they decorate walls and tunnels with drawings... (apart from that thing in that picture above)

Tunnels and extremely high noise walls are a common feature today.

Especially in mountainous areas where tunnels are now used even when they would not be mandatory (like the Italian A5, Aosta-Monte Bianco part, 25 out of 35 km in tunnel).

While tunnels are by no means legally necessary in the Netherlands, many view it as a way to "buy off" criticism from local / regional politicians and action groups.

A28 just after Landquart.



Klosters viaduct and Gotschna tunnel just after.





Küblis bypass, with a ~2.5 km tunnel (another tunnel of a similar length is under construction nearby to bypass Saas, a third one - the 4.5 km Gotschna - bypass Klosters).

Albula road and railway (the road is opened only during summer, during winter it is used for sleds, with their users carried by train). This road is a rather unknown alternative to the N3 towards St. Moritz.



N27 looking east.



Vereina shuttle, Sagliains terminal (on the south near N27, the other terminal is near Klosters and A28).

In case some forumer know, I want to bother you with a request for information: next Sunday I'm entering Switzerland via Passo del Bernina, which is a secondary route. How easy is it to buy a vignette autostradale around there?

Though I know the route there doesn't require one, they are required on A13 which I'll be taking the same day. I lived in Milano and always had a vignette or at least always bought one in Chiasso border station... so I don't know much about its availability elsewhere.

I suppose you can buy it at a gas station in Sankt Moritz.

Ropeway for the Linthal hydropower project.



A3W just before the end in Zürich.

A9 near Lausanne in a strange 3+1+2 arrangement (it's here).



A9 and Vevey seen from Les Pléiades.



The N1, built new in the 1950s for the Expo 64 in Lausanne. It links Lausanne with Bern avoiding villages and with some grade separated junctions. It has often 2+1 lanes, sometimes even 4, but on a single carriageway.

There is a fund (mainly) for road infrastructures, with 20.8 billions available (some other transport infrastructures, rail, road, etc, have different funds). This fund has for now a planned life of 20 years since 1st January 2008. These 20.8 billions are divided as follows:
* 8.5 for completion of the national road network (motorways-autostrasse-main roads), that is the plan approved in the 1960s (+ the A16, - the A6 Rawil), 1790 km out of 1893 km or 95% have already been built
* 5.5 for road capacity improvements (groups 1 and 2, see below)
* 6.0 for urban public transport
* 0.8 for main roads in mountain and peripherical regions

List of capacity improvement projects can be found here: http://www.news.admin.ch/NSBSubscrib...ents/17369.pdf (groups 1 and 2 = financed, 3 = planned but without funds, 4 = postponed until all previous projects are completed, planification and project studies abandoned)

More details: http://www.astra.admin.ch/dokumentat...e&msg-id=30041 (see also on the attachments on the right, they contain a description of the fund and of the projects - available in the three main languages, but not in English)

Maps of the critical point and the status of plans below. Please note that the "level" indicates the congestion (3 is the higher), while the "module" the financing status (1 is the most advanced). The two things are not linked: a section might be highly congested but have low priority. The alternative of public transport is always considered when planning roads and sometimes preferred.

A bit overkill for sound barrier I think... Coccodrillo is right though. It would have been better to just make it an artificial tunnel. Gotta admit though, the barrier is stereotypically Swiss clean.

Because it's new. Sometimes noise barriers and walls aren't cleaned, as I suppose that with their special material cleaning is quite expensive (if ever possible).

Middle noise barriers do help a lot, because barriers are usually most effective being closest to noise source. They are however obscuring views and could be even safety problem.
Today noise barriers are mostly from absorbing materials (as above case) and can also be cleaned, because material inside is not much sensitive to weather influences.

I prefer transparent noise barriers, but they can cost as much as 150% more

As for making it an artificial tunnel: it increases costs sharply, because a sector with barriers is still a overground sector, no forced ventilation, only emergency exits are needed. Put a tunnel and the costs go through the roof (pun intended).

Brünig pass (OW/BE), southbound (heading towards Interlaken)

2. Haslital -where ski resorts are- is accessible from here



3.




This road also comprises a very sharp-bended tunnel limited to 40 km/h

A lot of passes are already snow-covered or even closed. This also includes roads in the higher valleys like the Engadin (St. Moritz).

Lukmanierpass:


Oberalp: (1.600 m)

It looks pretty light. A few days of sunshine and it will be all gone again. We had snowfall like that a few weeks ago, gone within one day. Although the forecast in Mayrhofen doesn't look the coming week.

Winter 2010, driving from Zug (ZG) to Sattel (SZ) ski resort, distance ca. 30 km.
This is not a classical tourist route, and also the little ski resort at Sattel is rather frequented by locals.

1.


2.


3. Village of Unterägeri


4. The Aegeri Lake to the right - a small lake entirely within the Canton of Zug


5. Almost there ...

Unlike what it was said until now (also on newspapers), the idea of a second Gotthard tunnel isn't completely ruled out. A decision about what to do with the refurbishment of the existing tunnel will be taken next year, and the second tunnel option will be evaluated with the others. However, in the final situation (after the refurbishment of the first), the second tunnel would have only one standard lane, so to have still one lane per direction.
