Well, I am aware of that strange stepchild of a municipality, I was just being a bit facetious.



Eau Claire is far better known outside of that very local area, though.

In my view, multilane roundabouts are fine if the deflection of the approach road puts the path of traffic entering the roundabout on a tangent with the lane they should be in on the roundabout. This used to happen in the UK in the mid-late 1980s, but for some reason the deflection rules have changed where vehicles are put on a path that forces them to make a tighter turn as they enter the roundabout (not before).

The effect of this rule change is that lane 1 of the roundabout entrance usually becomes lined up at a tangential path with lane 2 of the roundabout instead of lane 1 and, hence, this encourages people to take a "racing line" when negotiating it. This is fine if no-one else is about, but with other traffic this leads to a lot of near misses where people from lane 1 cut other drivers up as they drift across into lane 2. It also works very poorly when roundabouts become signalised and where there are a lack of guide markings - marking standards in the UK at junctions are pretty vague and are getting worse in this respect, despite the UK's patronising "nannying" approch to transport in most other respects.

Well, this is a special roundabout... because is just a left-hand traffic roundabout in a country with right-hand traffic.

It's inside "Parking Alfonso el Sabio" in Alfonso X El Sabio Avenue in Alicante, Spain. This underground CarPark go along this avenue.



It's located on the lower (-2) level, and as you can see this roundabout it's designed for connect two sections (Zones) and their ramps (upper to lower level).













And you can se how long is this place...!!!


P.S.: Yes, that liquid that you can see on the floor is not water... is pee...

Just found what is possibly the worst roundabout statue in the universe:

In Liptovský Mikuláš, Slovakia they have this epic roundabout with a church in the middle of it..

Saint Pio would leave his grave and kill the "artist"

Much better the world's biggest chair in that roundabout in Manzano.

Four lane roundabout near Affi at the end of SS 450:



It is here but clouds cover it on Google Maps (but it's visible on Google Earth).

By the way, it's a pity SS 450 is not a motorway linket to both A4 and A22...

Roundabout in Castellón airport. This airport has actually hosted no flights since its opening last year, and will remain aircraftless for a long time. This statue is dedicated to its driving force, Carlos Fabra, president of Diputación Provincial de Castellón (Castellón province administration), who is involved in big corruption scandals.



Hope Benevento is OK with second place.

In Italy there is a never completed airport too, in Comiso, Sicily.

Well this one is complete. The only thing missing is air navigation permits.

Mmm, it's a tight war, but I still think that Saint Pio - Mazinger beats the airplane-eating clay beast

what about this kind of roundabout?



or something a little bit more crazy, the magic roundabout

You mean a standard turboroundabout?

Here's a map of all turboroundabouts in the world. There are 299 of them, at least, 299 are known. If you've got another one, you can submit it
It was a Dutch idea, that's why there are so many in The Netherlands. Hungary has quite a lot of them too.

[Rebasepoiss]

If only I knew the difference between turboverkeersplein or knierotonde, for example or any other category of turbo roundabouts

[ChrisZwolle]

Hmm, that site claims the capacity of a 3-lane turbo roundabout is 12,000 vehicles per hour. I highly doubt that, that's similar to 6 lanes of free-flowing freeway traffic.

Explanation + real-life examples can be found here

Does this one in Zaragoza count? At first it was a normal roundabout, but it caused traffic jams (Such roundabouts are called "rotontas" in Spanish, which could be translated into "round-a-fools") so it was repainted onto a turboroundabout. If your guys agree then it is missing from the turboroundabout map.
