Are there any bannered routes outside the US?

[pderocco]

I know British Columbia has had business routes at one point, if they don't still do.

They certainly have plenty of suffixed roads. BC97 I think has A, B, C, and D. But I don't recall seeing any actual banners anywhere.

Another difference is that you can reuse the same alternate route number in the same state, e.g., the multiple US-1As in Maine, but each 3di must be unique within the state.

TIL...

For four decades until 1996, Kansas had two highways numbered 150:

1.  One that connected to US-50 in Chase and Marion Counties.  This K-150 still exists.

2.  A continuation in Johnson County of MO-150, which itself is still connected to US-50 in Missouri.  This K-150 no longer exists because the towns around it had grown enough that it had nothing left outside municipal boundaries (plus US-169 was relocated), so now the western endpoint of MO-150 is just a city street in Kansas.

To me, a suffix and a banner are not the same thing.

They're not physically the same, but they often have the same meaning.

But not always. In Oklahoma, a suffix normally indicates a spur route, and it just ascends through the alphabet A-B-C-D-etc. So if you are expecting 63A to be an alternate of 63 and meet back up with it again, you are probably going to be astonished. Twice.

So the reason I remembered BC has bannered routes is because of this assembly on TCH 1 WB, which is the only sign for an old alignment of TCH 1 in Chase.

Also, TCH 1 and PE 2 around Charlottetown are signed as "BY-PASS", though the associated old alignments are no longer signed as business routes:

India appears to have a NH 10 "bye pass". No idea if or how it's signed.

Looks like this from the West Bengal side: https://maps.app.goo.gl/QbYUzboSZJh4xmoz8
The bypass is signed as NH 10 mainline.

I was unaware that New Hampshire state route 10 extended to India.

Not funny.

There's a lot of overlap between India's two letter state codes and the US'. Including the National Highways (NH) and National Expressways (NE).

Overall, India did take a lot of cues from the US/Interstate systems when they renumbered the entire NH system back in 2011 though. I do find India's fondness of suffixed 3dNH (NH 765D, 765DG, and 930P in Telangana, for example) numbering a bit annoying, however.

All's funny now.

Whatever you say, National Expressway 2.

Didn't Florida do the same thing as well with their suffixed routes?

[RG470]

Arizona is an example of a state that numbers some of its state highways like interstates too--look at all the x87 routes--but I don't think most states do that because they have so many state routes already. People wouldn't automatically think of route 234 as an alternate for route 34 if there were lots of other numbers in that range that weren't alternates

I believe Pennsylvania does that too

I also grew up in Massachusetts, which uses suffixes, but MA, NH, VT, and RI are different because they have no US route alternates. Instead, they create state route alternates for US routes, so those don't mean quite the same thing.

BYP US 1 (Portsmouth/Kittery), BUS US 4 (Rutland), and ALT US 5 (St Johnsbury) all say hi.

There's also BUS US 1 (Warwick), ALT US 6 (Johnston), BUS US 3 (Laconia), ALT US 5 (Derby Line), and ALT US 7 (Burlington).  Not to mention the truck routes.  That's correct about MA, though.

I was specifically referring to reliably signed routes, of which the other two Vermont examples you cite are not.
