S2 opens, unblocking east-west transit through Warsaw

I finally got round to it today - a very long (19,000 paces!) stroll from home to the western portal of the S2 tunnel, which was opened on Monday 20 December. 

Story so far - the A2 motorway/S2 expressway, which form the Polish part of European Route E30 (Cork to Omsk), got as far as Warsaw in 2012 (in time for that year's European football championships). Since then, transcontinental traffic heading east would get as far as this junction with ulica Puławska (below), and would then solidify into one huge constipated jam made up of local, regional, national and international traffic on Dolina Służewiecka. Now, over 11 years after the A2/S2 reached Warsaw, the route finally gets to cut through to the other side, via a 2.3km-long tunnel diving under the southern suburb of Ursynów. [The sign above the slip-road states that traffic over 16 tonnes is prohibited from using the S2 between 7-10am and 4-8pm. Much transit traffic will continue to use the DK50, but anyone who can will rather use the S2 - it's  27km shorter.]

For about two and half kilometres, the S2 runs parallel to a single-track railway line, the umbilical cord linking Warsaw's Metro system with the outside world. Rarely used these days (new Metro rolling stock now gets delivered by road!), the rails themselves are lightly coated with rust, suggesting the infrequent passage of a maintenance draisine. Below: looking west towards ul. Puławska, the slip-road joins the S2 to the right. The acoustic screens are effective - the roar of Puławska way behind me is louder than the traffic on the other side of the screen.


Below: looking towards the western portal of the tunnel. It dives down beneath the Metro, building the tunnel with minimal disruption to the Metro service was quite a feat of engineering! The sign says that average speed is being measured; cameras automatically capture each vehicle as it drives in and drives out of the tunnel and work out its average speed. You have been warned. 

Below: going underground. Above the tunnel, there has been much structural change to the fabric, the look-and-feel of Ursynów. I found it difficult to get my bearings along ul. Płaskowickiej, a street which I once knew intimately from morning runs to my children's primary school. 

I chose to return through the Las Kabacki forest. The Metro's rail link at this point, at twilight, takes on a very specific, eerie air. It is as if I have entered Tarkovsky's зона from Stalker by night...

Some subtle Photoshoppery going on here... That glow in the distance is from the Metro maintenance depot, but it feels like could be an atomic weapons manufacturing facility in the Urals...

On the way home I take the long way around to take a stroll over the ice on the pond on ul Pozytywki before it melts. The sign prohibits angling and littering, but there's plenty of evidence of ice-skating going on. Absolutely rock-solid ice - and you can see the high level of water in the pond this year. I like the horizon on this photo, the wires, lights and foggy sky.

Below: looking at ul. Pozytywki from the middle of the pond; a strong 1950s USA vibe. "Approaching the country club in midwinter."


I'd like to share two particularly atmospheric digital works from my brother; the one below is based on my recent photo of the new roundabout by the S7 extension viaduct - Cold fronts, Atlantic depressions and winter storms.

Presumably the metro link line is valuable when heavy things like ballast or track materials need to be delivered - once in a while, but useful nonetheless. Maybe also for moving plant like tampers for overhaul. In the UK the connections between the London Underground and the national network are like that.

As far as I can see online, the last time the metro link line was using for delivering new rolling stock was back in 2013, although as you say, it has less glamorous uses too. I'm sure I've seen at least a draisine trundling over the line since 2013. I'd guess London Underground has many more link lines than just the one that Warsaw has, serving two Metro lines.
