The speed limit on A107 is 90 km/h.

Sao Paulo's ringroad - when completely built its extension will be 177 km. Nowadays it has 93 km already done.

Nice bridge

M60 motorway, Manchester...
Not very big but still pretty interesting, and I travel over it on the train every day to work...laughing at all the people stuck in traffic lol

Length: 35 mi (56 km)

Junction with M62


Bridge


Near Denton

Now that is one fugly sign!

Projected Konya Ring road would be 110km long (compare with Ankara's 114 km ring)

Hyderabad Ringroad is the longest ringroad in whole of india. it will be a benchmark for rest of india. they have planned ORR well before the city traffic dwindles.

Copenhagens inner ring road is aprox 34 km including Amagermotorvejen (from just before Sjællandsbroen) through Motorring 3, the inner part of Helsingørmotorvejen and the new tunnel called Nordhavnsvej.

http://map.krak.dk/m/atiU6


Motorring 4 is only around 50% completed and goes between Ishøj and Ballerup, plans for a new part from Ballerup to Værløse (Hillerødmotorvejen) have been talked about but nothing detailed has been revealed.

http://map.krak.dk/m/atign

The last part from Værløse to somewere on the Helsingørmotorvejen will most likely never be build because of some larger lakes and forest north of Copenhagen.


Motorring 5 will be 70 kilomoters long and go from the southern satellite city Køge to the nothern at Helsingør but it has the same status as the Ballerup-Værløse part)

This motorway will also include a double track railway that will connect with a possible Helsingør-Helsinborg tunnel.

Dublin's M50 motorway is a partial-ring road that is 45 km (28 mi) long, and this includes the 4.5 km (2.8 mi) Dublin Port Tunnel.

Route map (includes diagrams of each junction).

There is a long-term plan to complete the 'ring' by building a bridge/tunnel combination through the south side of the city. This is known as the 'Eastern Bypass' and a feasibility study with possible routes can be found here.

Another long-term plan is for a 'Leinster Orbital Route', which will be a motorway built much further out of the city connecting the M1 and M7 motorways (via the M2, M3 and M4 motorways). A feasibility study with maps can be found here.

Some good photographs of the M50 taken last year by the Irish Air Corps:

Here's a nice video by rndomn8 on Youtube of a drive along the N12 Southern Bypass in Johannesburg. Together with the N1 Western Bypass and N3 Eastern Bypass it forms a 78 km ring around the city.

http://youtu.be/4RD38_aNQ5w

You can see the widening work that has taken place now to widen to at least 2x4 lanes and a cut-and cover tunnel being built at the Reading Interchange to upgrade a cloverleaf loop to a semi-directional ramp. Another interesting feature of the ringroad is that because it is formed by the convergence of three long-distance routes, between the Elands Interchange and Gillooly's Interchange the N3 and N12 are concurrent with each other (the N3 being a lower-numbered road takes priority).

Has anyone actually been keeping tabs on what the longest ring-road in the world is?

I was looking around at some major cities around the world, and Shanghai seems to have the longest: its G1501 is over 200km in length.

[ChrisZwolle]

G1501 is indeed the longest beltway in China at 209 kilometers. Other beltways, such as the Wuhan, Beijing and Chongqing Outer Ring Roads are also close to 200 kilometers in length.

The longest beltway under construction is the Ken-O Expressway around Tokyo. It will be around 300 kilometers long, out of which about 110 kilometers is completed. Another beltway is planned around Moscow, though it will run pretty far out side the city. This CKAD will be 522 kilometers long, and run approximately 60 - 80 kilometers outside of Moscow. However, this is an area where beltways become vague. These is also a concept beltway around Paris that compromises a number of bypasses. It is called the Grand contournement de Paris, and is approximately 850 kilometers long, being mostly 100 km or more from the city.

[lafreak84]

Grand contournement de Paris is everything but a Paris ring-road. It runs through other cities and it's part of their ring-roads. It has a shape of a ring but it's long long way from Paris. If you fire up GMaps you can see it almost complete:



It would looks something like this:


While Moscow CKAD makes perfect sense since Moscow is actually that spread out and needs more ring roads badly. This is the proposed ring-road.



And please take a look at this satellite photo of Moscow at night in my thread "pictures from space" http://www.skyscrapercity.com/showthread.php?t=1443341 :

CKAD will actually be a beltway while Grand contournement de Paris is nothing but connecting motorways that happen to form a shape of a ring.

Wow thanks for letting us know about that thread

2 more to add. The Osaka loop road will be about 200km and the Nagoya will be 160km.

Bulgaria

Sofia's Ring Road - 60,2 km

But it's not still all at motorway standard, and will be shortened in few years by some 8 km by the Northern Speed Tangent (shown in blue in the picture bellow), the old more distant northern part of the ring road will remain 1+1.

[prophecus1]

(From Latar expressway website)

The proposed Kuala Lumpur outer ring road would have a distance of about 130 - 150 km. The western, northern and southern parts are completed and in service. The eastern part is in planning and would pass through mountains and jungles, hence environmentally sensitive area.

Even its interchanges aren't compatible, Ankara will have a 62km long inner ring after a completion of a short missing link: http://harita.yandex.com.tr/-/CJe1EIjy
