There's a wide-radius 180 degree turn at the bottom of the M3, if you are going southbound and turn east onto the M27
Driving thrombosis caused this accident......a clot behind the wheel.

From the SABRE Wiki: A4061 :


The A4061 is a bit of a dark horse. Superficially, it looks like a typical local road linking lots of former mining communities in South Wales together. However, on closer inspection, it reveals itself to be an excellent driving road, full of fun twists and turns. It's popular with bikers as an alternative route from the M4 to the A465.

The A4061 starts in the centre of Bridgend, at a junction with the A4063, and immediately crosses the River Ogmore to head northeast

That looks like the only hairpin that can be taken at 70mph :D

Of course up in the mountains of Scotland you would find some.

The infamous Bealach na Bà road to Applecross, there is this series of tight hairpins going up/down hill and single track too.

Been up here a few times, the first time I went up my cars turning circle wasn't so great and needed a small reverse to actually get round one of them.

Our forum member Jon from Auto Shenanigans has just made a video about these bends:

The bends at Hardknot Pass might not be quite 180°, but there are a lot of them and they are not signposted as bends!

A totally different sign in Johannesburg. This particular northbound descent features a 190°bend. About 2 m away is a similar 180° bend, except that th downhill slope is on the sourthern side of the ridge. Interestingly, any rain that falls on the northern side drains into the Indian Ocean and rain that falls on the sourthern side drains into the Atlantic Ocean. In 1970/1 I had a flat about midway between the two which was right on the ridge.

And now for something completely different; my grandparents lived in Brentwood and I had aunts and uncles in Harold Park, so this weirdness on the A12 was the best way to get back whenever we were visiting.

(I'm sure it used to be even tighter when I was as a kid but I think they rearranged it later.)

Madrepore Road, Torquay, one way downhill. The uphill equivalent is the straight and very steep Stentifords Hill Road

Some tight 180 bends on the way into Ballintoy harbour https://www.google.com/maps/@55.2433313 ... ?entry=ttu

180 over a bridge on the A2 near Cushendall https://www.google.com/maps/@55.1281571 ... ?entry=ttu

Saintfield, I occasionally see cars attempt to turn 180 up Comber Street https://www.google.co.uk/maps/@54.46653 ... ?entry=ttu though it's uncommon as both roads are headed the same direction, if they needed this way they might have turned through the town. Usually ends up a small 3 point turn.

A longstanding favourite is this road on the north coast of Majorca, which I always like to take the hire car down when visiting

https://www.google.com/maps/place/Palma ... ?entry=ttu

The 270-degree bend on the right hand edge there is interesting, I don't know another road having anything like that, although some railways do so to gain/lose height.

There’s this >180 bend on the E25 near Genoa.

Edit: Done in the name of a big change in elevation but the link in the post below shows it better!

Another "all the way round" junction is on New Clearwater Bay Road in Hong Kong. I used to catch the bus along that route.
