Hålogalands bridge 1145m, Norway

[Ingenioren]

Scheduled to start construction during spring of 2012 and with completion in 2016. Situated on E6 north of Narvik, it crosses the Rombaks fjord and will shorten the main north-south highway in Northern Norway by 18km, the bridge open up new development land north of the fjord for Narvik and allows for closing of the local airport. Total bridge length will be 1533m, but the main span will be 1145m and towers will reach 180m. Project costs are 2400 million NOK ~ 310 million Euro including 6,4 km accesroads and a 1km tunnel - roughly 1/3 NOK will come from tolls.

Impressive. The tolls are rather steep though.

It's damn beautiful!

They have mustangs in norway??

Why do most new Norwegian bridges have to have only two lanes?

[ChrisZwolle]

Because the traffic volumes are likely less than 10 000 vehicles per day. There is no need for multi-lane highways that far north.

We don't even have any suspension bridges with more than 2-lanes... This one is estimated to carry around 5000-6000 vehicules even when the tolls are removed 15 years after opening.

There are some examples of under-dimensioning large bridges. Nordhordalands bridge was built in 1994 and now carries 15000 vehicules. Grenlands bridge opened in 1996 and carries 13000 vehicules. Askøy bridge opened in 1992 and carries 17000 vehicules,

So, every time you want to save 18 minutes, you need to pay NOK 100, about 13 euro (minus discounts). Time really seems to be money in Norway.

An interesting decision is to put a toll booth on the current E6/E10 multiplex. The E10 traffic to and from Lofoten will be charged a toll without getting any benefit from the new bridge.

They get the 1km tunnel... Alternative roads are usually tolled or get speedbumps, low speed limits etc. to make them less attractive.

That is evident. But in this case, the toll will not be put on the alternative route (the old section of E6 to be downgraded), but on E10. There is no reason the make the E10 less attractive.

[Ingenioren]

It's motivated by the tunnel. Altough i agree it's to much for such a short tunnel... It could be 10kr there and 30kr on Rombaks bridge or somewhere else on the old E6 instead... Ideally we would have longer downpayment period and lower tolls on the main bridge, but no tolls on alternative road.

Yes, we have. There at least 3.000 Mustangs in Norway (that's the number of Ford Mustangs in the Norwegian Mustang Clubs register).

Approved.

The 1533 meter long bridge will have a span of 1145 meter, shorten E6 in Nordland county by ~18 minutes north of Narvik. It will have two lanes, summening up to 9,5 meters wide profile.



Construction start is this fall, and cost is just under NOK 2,5 bio (€330 mio)

What is the purpose of the additional barrier outside the normal railing? Suicide barrier? Wind screen? I've yet to see anything like it on another bridge.

Good question.

From the renders it doesn't look like it will be very good at stopping wind or people wanting to jump. Could it be that it breaks up the air flow (causing turbulence around the tube / wire-like structure in the fence) so that the wind doesn't cause unwanted oscilations in the bridge itself?

I agree that it doesn't appear like it would do much in stopping wind for traffic on the bridge. Usually those barriers are much more substancial. As for dimishing oscilations of the bridge itself, again I've yet to see anything like this used as such. I know currently under construction in Norway is the Hardangerford bridge with a deck of similar size and arangement (one lane each direction with a pedestrian / bicycle path). That bridge uses "fins" on the deck's underside for stabilzation as seen in the first half minute of this video.

I believe that the difference is that the Hardangerfjord bridge is situated on a much less windy place whilst Hålogalands bridge is situated at a place where it will be very windy. Typically, between Stadt (just south of Ålesund) to Troms the southwestern winds tend to be very strong, and Hålogalands bridge will be met head on by these winds. Still i don't know the purpose of the barrier, but its rather for wind than preventing people from committing suicide!
