Zug City Tunnel

There is a tunnel planned with four branches and an underground roundabout in the city of Zug (population 28,000). The aim is to reduce traffic in the central area to a minimum.

The city of Zug has approved 100 million CHF for the project. The total project cost is 890 million CHF (€ 740 million). This will be funded through;

* 100 million from the city of Zug
* 300 million by raising the cantonal road tax by 25% for a period of 27 years.
* 490 million from the canton of Zug

I doubt if this huge investment is justified in a small city like Zug. On the other hand there don't seem to be any competing cantonal road projects in the small canton of Zug. (Yes, an extension of A4a to A3 would be nice but that's a federal project).

Zug is extremely wealthy, I think.

That is exceptionally high cost for just 3-4 km of tunnels - probably they will have just one tube each. Wouldn't be cheaper and more effective to have eastern bypass, even if it was whole in tunnel?

Something similar exists in Tromso, Norway. I wonder if there are other underground roundabouts in the world.

And one in Frauenfeld: https://maps.google.ch/maps?q=Frauen...govia&t=m&z=18

And some more around Norway (and some junctions inside tunnels but without roundabouts).

********************

They want to make a fully or partly pedestrian zone in the city centre, or at leas reduce non local traffic as much as possible. That's why the tunnel ha sso many portals near each other. Anyway Zug is the richest canton, at least compared to its size, and as far I know there aren't any other big cantonal road or rail project.

There's at least one underground roundabout in Monaco, too.

It is called "the Canton roundabout" referring to Swiss Cantons :

A similar project is in the pre-construction phase in Feldkirch, Austria. The environmental impact assessment is in progress.

The opening dates of the upper section of the A9 can be seen here: http://www.a9-vs.ch/eroeffnungsdaten...nanschauen.pdf

Turtmann-Steg, 8.1 km, in 2017 without Riedberg tunnel (a short tunnel that caused some technical problems)

Eyholz tunnel, half of Visp's bypass, should open in 2018 (by that time, Vispertal tunnel, the other half of Visp's bypass, should be closed for refurbishment and final works)

The opening of the remaining section is not in sight, but should be around 25 years after the beginning of the works around 2000.

15.8 km out of 31.8 km, or 49.7%, are in tunnels.

If I got it right: The eastern part of the bypass will be opened in 2018 (both tubes). The first tube of the western bypass will temporarily be closed afterwards (refurbishment).
What's about the 2nd tube of the western bypass, will it be opened in 2018 too? When will the refurbishment be completed, 202x?

Yes, so transit traffic will follow this route afetr leaving the eastern tunnel: https://maps.google.ch/maps?saddr=Ta...p=1&sz=15&z=14

Quote:

Yes (although it may be closed before the opening of the eastern tunnel).

It is already used as a two way tunnel: https://maps.google.ch/maps?saddr=St...sz=14&t=h&z=14 (only for Lausanne-Sion to/from Vispertal/Zermatt traffic, it makes no sense to use this tunnel for east-west traffic)

But it will be converted to the eastbound tube of an Y-shaped double tube tunnel. Boring of the westbound tunnel should have started recently.

Except the two sections I cited in the post above, all the others (including the western bypass tunnel) are said to be opened in 202X, which means nobody knows when.

I read that the existing tube of the Vispertal tunnel will be closed for 18 months, but I don't know what does this mean. Maybe that it will reopen earlier than the first opening of the other tube. If that's the case, I suppose that eastbound the bypass will be fully opened before 2020, but eastbound only half of it.

We will see, this motorway has been promised decades ago and is under construction since 15 years, so every small bit is very welcomed.

Obviously not a high priority or it would have been already finished.

Speaking of Norway, both ends of the Hardanger Bridge.

Are the roadworks resuming between Steg and Visp? Is the area surrounding the motorway construction has been decontaminated?

For reminder, during the works of A9 in Raron, the biggest mercury-polluted site in Switzerland was discovered; with concentrations up to 3500 mg/kg, the Federal limit by law being of 5 mg/kg (700 times over the norm). This pollution is due to savage rejects of mercury in a canal joining the Rhone, between the 1930's and late 1970's, by the chemical plant Lonza in Visp.
Moreover, the highly-contaminated embankments of the canal were used in large scale in fields as fertilizer, and as backfill in residential areas .

Geneva to vote on lake tunnel again

Quote:
Three months after a similar initiative was rejected at the ballot box, voters in canton Geneva look set to decide again whether to build a road tunnel under the lake.
The committee behind an initiative to construct a four-kilometre lake tunnel near Geneva handed in signatures on Monday to force a local vote which could take place in the next 12 months.
The road tunnel project, launched by the centre-right Radical Party and centrist Christian Democratic Party, aims to combat chronic traffic congestion in the city centre.
Initiative supporters claimed the new tunnel would be different from the shorter 1.5-km “Rade” tunnel project, which was turned down by 63% of Geneva voters in September 2014. They said it would link up to the cantonal ring road and Swiss-French motorway network and would be located at the wider part of the lake, east of the city.
Supporters said the new, longer tunnel would therefore ensure transit traffic didn’t end up crossing the city and snarling up main lake crossing points like the Mont Blanc bridge.
The tunnel will cost CHF2.7-3.3 billion ($2.67-$3.26 billion) and is not likely to be realised before 2030 at the earliest.
A positive vote will send a clear signal to the federal authorities in Bern, which are hesitant about financing such a large infrastructure project that they do not consider a priority.
The question of whether to build a bridge or tunnel in Geneva to help people cross from one side of the lake to the other and ease congestion has been debated for years.
Prior to last year’s vote, in June 1988, 68% of local voters agreed in principle to a new lake crossing. However, in June 1996, two-thirds of voters rejected plans to build either a tunnel or a bridge across the lake.
