You have to think long-term. It won't need any renovation in the next 10 or 15 years, but by the late 2030s traffic volumes will have increased to a point that single lane traffic will cause significant traffic congestion. Traffic counts from 2005-2010-2015 in Poland already showed significant traffic growth on the motorways.

What if - for example - A2 carries 50,000 - 60,000 vehicles per day. You can't narrow that to single lane traffic without causing significant delays and associated collisions. Just look at the experience in Germany with all their Baustellen, with many having severe traffic congestion even if there are two narrow lanes.

Traffic won't grow indefinitely. And since Poland is depopulating, it may even start decreasing.

I don't know about Poland but the mileage per inhabitant is still increasing in Germany. That means, even if the population is decreasing, traffic is increasing...

The same is recorded in the Netherlands. Areas with a population decline or stagnation saw traffic growth, which was most pronounced on the motorways. This is also observed in Denmark, motorway traffic grows much faster than rural and urban traffic.

Traffic will increase in Poland. Up to a few years ago it was surprising in Poland to commute by car even 40km to work, whereas in the West that's very little for some people.

Let's not forget that better roads generate more traffic.

You just add another lane, there's no need to tear down the existing lanes.

A4 in concrete, widened at the interchange with S3:

BTW Poland starting with 2017 is no longer depopulating. Not only we have net immigration but natural pop. growth as well.

Traffic is also growing by up to 5% p.a.

Does that mean that the entire S2 is now under construction?

Nope, section A (the one with tunnel) and part of section B still don't have construction permits. Nor does the Lubelska interchange (S2/A2/S17).

Detailed map created by one of polish forum users is avaible there https://dl.dropboxusercontent.com/s/...ka-igorsel.png
It's Facebook site of this project where are news about updates and links

It would be nice if all european countries had also high quality map of highways.

DK20, bypass of Kościerzyna is opening today.
http://www.openstreetmap.org/#map=14/54.1194/17.9787

Construction took 24 months
7.6 km, 2+1 lanes, four junctions.



The bypass was originally planned as 2x2 motorway-like road, but it was "optimised" to 2+1. It is said to have space reservation for the 2nd carriageway, but it seems very unlikely that it will ever be built.

One curiosity about this bypass is that the junction Kościerzyna West is split between two streets: Leśna and Kościuszki.

I cannot recall similar solution anywhere else.

Google Earth altitude data suggests there is a 10 - 15 meter height difference east of road 2403G, where an off ramp would have been located. That may have been a reason to build the ramp further west.
