Title: Routes that form a complete loop
Post by: hotdogPi on February 18, 2014, 03:54:34 PM
This is the route that never ends.
It just goes on and on my friends.
Some people started driving it not knowing what it was,
And they'll continue driving it forever just because . . .


M-185
Australia 1
Iceland 1
I-285 (Atlanta)
I-465 (Indianapolis)
I-270 (Columbus)
I-275 (Cincinnati)
A86 (Paris)
I-410 (San Antonio)
I-495 (Washington D.C.)

I-295 (Jacksonville)

Some but not all Texas Loop routes are full loops, such as Loop 8 around Houston, Loop 289 around Lubbock, and Loop 1604 around San Antonio.

The recently-completed Circle Drive around Saskatoon SK (part of which carries TCH 16 around the city).

There are more if you accept full loops pieced together from two or more routes, such as I-494 and I-694 around Minneapolis and St. Paul, or TCH 100/MB 101 around Winnipeg.  M25 around London would be one of those, since that route doesn't include a toll crossing east of London which is assigned a non-M route number.

Depending on whether you include the mostly-signed (but ultimately unofficial; older signs show it but newer ones don't) multiplex with I-490, the Inner Loop (for now at least).

Looks like AB 216 will be a loop eventually.

Spain: M-30, M-40 (Both around Madrid), SE-30 (Seville), Z-40 (Zaragoza) are all full loops. SE-40, another loop around Seville, is expected to become a full loop sometime in the future.

Elsewhere:
Italian A90 a.k.a. GRA (Grande Raccordo Annulare) around Rome (and Vatican city :sombrero:)
MKAD around Moscow
German A10 around Berlin
South Korea expressway 100 around Seoul
And in China, any expressway numbered Gxx0x is slated to become a full loop if it doesn't already.

At one point in its life, MN 100 was a full loop.  MN 110 and what's left of MN 120 are remnants.

Herndon Parkway around Herndon, Virginia. I have no idea what route number it carries, but it's basically an at-grade beltway around the town.

Per VDOT, it has two different route numbers on separate segments.  Neither of which are signed, as I recall.

NYC was supposed to have a complete parkway loop around the edge of Brooklyn and Queens - this is where the name "Belt Parkway" comes from. The loop was eventually completed, but the western side of it was built as expressway rather than parkway (BQE) and part of the northern side of it became the Whitestone Expressway. Nonetheless, the loop can be easily followed on a map (https://goo.gl/maps/Uv7rP).

Depending on how you look at it, either 1/2 or 3/4 of it are signed as either VA 228 TRUCK or SR 606 TRUCK.

Officially the route is designated as 235-6658 (southern half between the SR 606 jcts) and 235-6660 (northern half).  235 is the numerical code maintenance jurisdiction number for the Town of Herndon.  Fairfax SRs 6658 and 6660 exist and are elsewhere.  As far as I know none of the Town Jurisdiction routes or the Urban Routes in the Independent cities are signed in any way.

Thanks to both of you. I can picture seeing the TRUCK 228 signs, but it's been a year or two since I've used that road and I just didn't remember if there was another number. I used to give my father a lift out that way fairly often to a mechanic he used, but they no longer have that car so I no longer make the trip.

That one's tricky; it's not entirely clear whether "Inner Loop" constitutes a defined route in and of itself. Reference route 940T comprises only the non-490 portion of the loop, and therefore doesn't form a complete circle. However, the Inner Loop in concept, as well as in early construction, predates the existence of I-490. The original design (http://www.rochestersubway.com/images/photos/rochester_innerloop_proposal.jpg) (which more closely resembles the shape of the orange-and-white trailblazer) was part surface boulevard and part freeway, and was initially built as a full circle (http://heckeranddecker.files.wordpress.com/2010/02/inner-loop-1970-crp.jpg), more or less independent of the nascent I-490. I don't know if this form of it was ever completely designated 940T; we can deduce at least that NY 383 played into the western leg of it (from old reference markers on Plymouth Avenue), but I don't know if the reference route system goes back that far.

A rare, railroad example used to exist in Toledo, OH.  The Toledo Terminal was a switching railroad that made a complete loop around the city.  The beginning of the end was in 1982, when a train derailed while on the upstream of the loop's two crossings of the Maumee River.  The bridge was damaged in the derailment and never repaired, so the tracks leading from the bridge to the nearest junctions on either side were eventually abandoned.  Today the track is gone in at least two stretches west of the river, including the bridge over I-475 near Douglas Rd.

Edit:  The damaged bridge can be seen from the Ohio Turnpike (I-80/I-90) as it crosses the Maumee River.

Loop subways are fairly normal, it allows for more stations to be serviced without having to engineer a turnaround area or having to reverse at any point. Many people mover systems are setup in permament loops such as the dallas airport's.

I believe that is at the Dartford Crossing bridge/tunnel. The crossing is toll, which probably violates MOT motorway standards.

I read somewhere that the reason for designating that portion as a non-motorway is to allow traffic that would be prohibited from using a motorway to access the Thames crossings there because they are the only crossings east of London other than a ferry.

no such thing as 'motorway standards', but certainly certain people disagree/have disagreed and not sort legal orders for their schemes due to very minor and silly 'violations'. Even so, Dartford is up to 'standard', or near enough.

If a toll violates standards then the Severn Bridges wave, as does the M6 Toll. But Dartford is OK on other factors too.

closer, but not quite.

The A282 is A282, and not M25 as the first bore of the Dartford Tunnel opened in the 60s, and the second a few years later. When the first bore opened it was a local scheme, and the line of the motorway hadn't been determined by then, so it opened as a bog standard road.

This created a right of way, which needs a lot of effort to remove,  and it was never considered worth removing, or creating a parallel alternate route to make the crossing (and approaches) a motorway.

Then there's (Lansing) Michigan's Capitol Loop, which despite the name is not a loop.  Well, it has a "loop" in the middle of it, if a rectangle is a loop, but there's tails coming off both ends of the rectangle to connect to I-496.

And the ever popular "Yooper Loop" in Houghton, where the NB/SB (actually running E-W) one-way sections of US-41 make a loop.
