Worlds longest beltways / ringroads

[ChrisZwolle]

Maybe it's interesting to make a list of beltways / ringroads / circular roads / orbital roads / circumferential roads or whatever they call them in your country.

the Netherlands

A10 Ring Amsterdam 32 km
A4/A15/A16/A20 Ring Rotterdam 41 km

Germany

A10 Berliner Ring 196 km
A100 Berliner Stadtring 22 km (not completed)
A1/A3/A4 Kölner Ring 52 km
A99 Autobahnring München 54 km (not completed)

Belgium

R0 Ring Brussel / Bruxelles 75km
R1 Ring Antwerpen 17 km
R2 Ring Antwerpen 13 km
R3 Ring Charleroi 33 km
R4 Ring Gent 61 km

France

Boulevard Périphérique Paris 35 km

The ring Antwerpen is bigger: R1, A11, R2 and A12 are part of that Ring.

Australia

Sydney Orbital Motorway - 110 km
M80 Metropolitan Ring Road (Melbourne) - 38 km (not a complete loop; it is not connected to the newly built Eastlink and there are no definite plans to build a connection, but it may live up to its name someday)
Perth ring road - 94 km (never heard it described as a ring road, but State Routes 2 and 3 do form a complete loop, even though route 3 isn't freeway standard all the way)

No other Australian city has anything resembling a ring road, unless you want to count the two-kilometre State Circle around Parliament House in Canberra.

What counts as a "beltways / ringroads / circular roads / orbital roads / circumferential roads or whatever they call"?

Only full circles? If not,here are some:

Győr(between main road 19 and 85):~23km(M1)
Nyíregyháza(between main road 4 and main road 4):~22,5km(M3 and main road 403) currently
Debrecen(between main road 4 and 35):~11km(M35 and nothern bypass) currently
Kecskemét(between main road 5 and 54):~17km(M5)
Szeged(between main road 55 and 5):~9,5km(M5 and M43) currently
Székesfehérvár(between main road 7 and local road in Szabadbattyán):13,5~km(M7)
Miskolc(between main road 304 and 3):~5,5km(M30) currently

[ChrisZwolle]

Not necessarily full circles, but bypasses are not beltways. I'd say at least three quarters around a city or/and functions as a beltway.

[Timon91]

The future MKAD was about 500 kms, right? The new Kiev beltway will also be 200+ AFAIK.

[Perennial Quest]

Could the "tangenziale" system around Milano (A51+A4/E64+A50/E35) be considered too?
I don't know its length.

[ChrisZwolle]

I think it can be, though it's not a very aesthetic loop like the GRA.

It sure isn't aesthetic, but it's kinda "closed figure" and it should be more than 60km in length. On Italian Wikipedia I found these informations:

A50 - 31,5 km
A51 - 30,1 km

The "urban" part of the A4 should be something like 17 km (measured with Google Earth).

Forget measuring distances like that, Map24 does the job for you; the Milan(o) Ring measures 65 km.


Ljubljana Ring A1/A2/H3 (Slovenia) - almost 30 km

Indeed.

And what would be the length of that one?

[Treasure]

So basically Tokyo has the longest ring/beltway in the world? any pics of it

[ChrisZwolle]

The Ken-O is still under construction. As far as I know, it is the longest beltway that is under construction. The Moscow / Kiev beltways are still plans as far as I know.

Spain

Barcelona 37 km (inner ring, Ronda de Litoral and Ronda de Dalt or B10 and B20)

[Minato ku]

France
RN844 - Nantes (43 km)

[ADCS]

US:

Capital Beltway (MD, VA): 64 mi (103 km)
Interstate 287 (NJ, NY): 99 mi (159 km)
Interstate 275 (OH, IN, KY): 84 mi (135 km)
Beltway 8 (TX): 83 mi (134 km) (Proposed State Highway 99: 170 mi/274 km)
State Route 840 (TN): 78 mi (125 km) (Total planning: 186 mi/300 km)
Interstate 295 (VA): 53 mi (85 km)
Hampton Roads Beltway (VA): 56 mi (90 km)
Interstate 494/694 (MN): 74 mi (120 km)
Interstate 435 (KS, MO): 81 mi (130 km)
Interstate 270/255 (MO, IL): 81 mi (130 km)
Interstate 465 (IN): 53 mi (85 km)
Interstate 285 (GA): 64 mi (103 km)
C-470, E-470, Northwest Parkway (CO): 85 mi (137 km)
Interstate 280/680 (CA): 127 mi (204 km)

The list is by no means exhaustive, but many of the more significant beltways are on there

[Ron2K]

Johannesburg has a ring road, comprising of the N1, N3 and N12 (three freeways that converge on the city). Total length is 76km.

Cape Town doesn't have a ring road - there were plans to extend the R300 and make it a ring road, but these are on ice at the moment. Durban doesn't have one either - the N2 may be called the "Outer Ring Road", but it's more of a bypass than anything else.

[ChrisZwolle]

Coastal cities usually don't have real ringroads, only bypasses.

[Mateusz]

Well, Sankt Petersburg will have a full ring road
