There are 3 pylons, spans are about 60m + 130m + 130m + 60m. Altogether the bridge is 402,5m long and 39,8 - 44,7m wide (width is variable), slightly curved (R=1500m). Here's what it basically looks like:

What is extradoses bridge and why was it chosen as the best solution? I haven't heard this term before. At least not in English.

Switzerland actually pioneered extradosed bridges, the Ganterbrücke at the Simplon Pass was the first extradosed bridge in the world.

An extradosed bridge looks like a cable-stayed bridge, but it actually works more like a box-girder bridge. A cable-stayed bridge carries almost 100% of the forces through vertical cables. This is only 20 - 40% at extradosed bridges which carry the forces much more horizontally than regular cable-stayed bridges.

Extradosed bridges are neither cheaper nor more efficient or easier to design than regular box girder bridges. However, the cost difference is often small. They are only efficient for medium spans between 150 and 250 meters. The longest span of an extradosed bridge is 275 meters; the Kisogawa Bridge in Japan. Extradosed bridges are usually only for aesthetics.

Poland has the largest extradosed bridge in Europe, the bridge at Kwidzyn (currently under construction). The Mszana Bridge is the widest curved extradosed bridge. The Sunnibergbrücke in Switzerland (near Klosters) is an example of a smaller curved extradosed bridge.

It was chosen over other solutions because the main criteria was maintaining "openness" of the valley below (as few and as small supports as possible), while keeping it within reason in terms of economics. Full blown cable stayed bridge would have been much more expensive. I'm pretty sure it was possible to go for a girder bridge with 3 supports, if they were large enough... So it comes down to the fact that secondary criterion was aesthetics, in hindsight it's easy to say they should have gone for a girder bridge, but the decisions were made long ago and we have to deal with what we have.

But will the completed Mszana bridge allow the A1 between Swierklany and Mszana to be opened as previsionally planned in August this year?

I'm not sure what you mean, the bridge isn't completed and the contractor who was meant to finish it (Alpine) said they won't. August opening is out of the question, we'll be lucky if they open the bridge this year.

Here's two fresh photos of MA532, try imagining how challenging it was to design this thing, given how wide it is and that there is no steel girder underneath - all forces have to be dealt with by the post-tensioned concrete box...

Is this the Walichnowy interchange?

Progress on S8 looks good for a 2014 opening.

Yup exactly, this is Walichnowy intersection. Notice: you can compare these photos with the previous ones that I took in September 2012. Of course if you have time to browse through this thread and find them
