Odd Aussie highway

[Alps]

In Tasmania, NR1 junctions itself south of Launceston. While the part north into the city is really just a spur, all of the legs are signed as 1, so it really counts as a 3-legged route. Does this happen anywhere else in the country?

Don't know about Aussieland, but it's all over Mexico.

[agentsteel53]

here in the US, we have I-710.

here in the US, we have I-710.

Which is not signed to go two different ways heading southbound, making it a simple case of implied 'to'.

[agentsteel53]

you're right.  710 isn't signed on all branches.

the Hell?  does Australia not have a tradition of banners like SPUR?  if so, it is very much like Mexico as you defined.

I can't think of anywhere else, except for roads that loop back to end at themselves.

I haven't come across this problem anywhere else in my route, but my route does not delve very deeply into most of the states' networks.

Apparently NH1 also junctions itself in the Northern Territory. http://goo.gl/maps/zTFQx

The routings to the south and west of Katherine are the implied mainline, though 1 changes from a national highway to a national route east of Daly Waters. http://en.wikipedia.org/wiki/Highway_1_(Northern_Territory)

I don't know what I'd do if I saw this in the USA. Already confusing enough for some people to drive in some places in this country, it wouldn't help for routes to intersect themselves.

[Molandfreak]

Wasn't I-865 in Indy also renumbered because of generally the same problem that I-465 intersected itself?

[NE2]

US 281 does this at Pha Pha Pharr, TX. To the west is defined as a spur (and as Spur 241), but signs show it as another mainline (signed east-west, as is the official mainline to Brownsville).
Coming off the bridge from Mexico you see this:

and then this:

In the US, IL-172 used to have three legs until 1974.  One leg went south, one went east, and one went west.  The west leg was dropped.

the Hell?  does Australia not have a tradition of banners like SPUR?

As far as I am aware, banners of any sort (Business, Spur, Bypass, Truck) are a distinctly American tradition.

We have a lot of these, in the UK, though looking at some of the more egrious ones (including two locations where 2 spurs heading off in different directions from the same junction, making the road look like it crosses itself), we tend to avoid signing them as such - using Bracketed routes* at the junction, even if afterwards it is signed as the route it is (on route confirmation signs, at any junction on the spur, etc)

However

• 2 out of the 3 arms are signed at this junction as the road you are already on. The 4th is also that road
  
• A627(M)? but I've just turned off that road!
  
• 3 arms of this roundabout clearly marked as A40. The 'rogue' one via Hwlffordd functions like a business loop, getting back to the A40 heading to St Clears (at a junction where it isn't signed as A40).
  
• You are on the A35, and the road forks into two A35s... - to make matters worse, the one signed for Fareham and the University isn't the way you want to go for either of those places - you want to do two sides of a triangle as it is quicker.

*effectively 'To' banners, which most countries have in some form, unlike the other ones.

I haven't come across this problem anywhere else in my route, but my route does not delve very deeply into most of the states' networks.

Some Virginia state facility routes have multiple posted branches off one another...

Ones with actual route shields on their internal postings: 357, 358, 369
Honorable mentions: 319 and 376 which are posted with shields only at connections with other primary routes but have gobs of rectangle postings at multiple branching intersections within their respective facilities...

MA 127 used to end at itself.

No comments on the real world example of US 281? You guys suck.

Someone sets himself on a high pedestal, above the rest of us peasants.

Happens twice in Oklahoma. OK 63A is a Y-shaped route (3 termini). One end connects to OK 1/63, and the route forks off in two directions.

OK 77S has four termini. The main part of the route is a U-shaped highway around Lake Murray. Two spurs branch off from this route to I-35 and OK-32.

This seems to be signed only at the south end based on the Goog and http://www.okhighways.com/ok63a.html

PS: love those Oknoname Reservoirs.

This one doesn't look to be fully signed, but has enough signs to be weird: https://maps.google.com/maps?ll=34.071218,-97.101717&spn=0.028972,0.056691&t=m&z=15&layer=c&cbll=34.071117,-97.101688&panoid=-FXvtQ9_lNd2Ly6TX_CP6Q&cbp=12,17.3,,0,2.13 and reassurance behind.

I wanted to find out in particular if this happens elsewhere in Australia. I'm well aware of other real-world examples.

[Bickendan]

Two I can think of offhand: I-895 in Baltimore (that spur really should be an I-97 extension), and OR 223 in Dallas, a complete three-legged highway.

The spurs aren't part of I-895, they're numbered 895A and 895B. And aren't in Australia at all.

Aside from driving on the left, that really looks very "American."

The BGS seems pretty clear to me.

The light poles look very much like Delaware DOT-standard.

EDIT:  I see what you mean after  looking at the map.  Seems like Route 1 headed north as Midland Highway ought to be bannered as SPUR or BUSINESS SPUR (if those are allowed in Australia).

You wouldn't know it by signage.  There are no OK 63A signs at the split or anywhere other than just north of OK 1/63.

I think the idea is that the three largest cities are along Highway 1 and the National Route.
