Child routes longer than their parent routes

[Alps]

US 202 is longer than the eastern US 2 (from which it branches).
NJ 124 is longer than NJ 24 (124 is old 24).
NY 481 is longer than I-481, although that's more of a continuation than a parent/child situation.

Basic rules: 1) consider the entire route, not just within the same state. 2) clear parent/child relationship. one must be a spur from the other as more than just coincidence, or an old alignment, etc. ideally, they share the same root number (that is not a pun). NJ 167 is a child of US 9 because it's an old alignment, for example. NJ 152 is not a child of NJ 52 because although numbered coincidentally, they are not related to each other.

US 278 is longer than US 78.

US 191 is longer than US 91

Really old example: I think that the original VA 251 (mid 1920s, when Virginia's 3-digit routes were spurs of 2-digit routes) was longer than VA 25 at one point.

US 421 is longer than US 21.

Only example in Indiana.

I would guess SR 129 is longer than SR 29. Also, you could count the child routes of state roads that no longer even exist - for example SR 21 (SR 121), SR 34 (SR 134, 234, 334).

Most all 3 digit Indiana state roads are children of a 2 digit parent US or state road (or Interstate in interim situations). The main exception I can think of is SR 135 which is not a child of US 35.

OR 138 is longer than OR 38.

Yeah, 129 is a bit longer than 29.  They're so far apart I forgot to consider them.

US 421 is longer than US 21.

But was that the case:

1.) Before US 21 was truncated? (First at Charleston, WV; later at Wytheville, VA)
2.) Before US 421 was extended? (First into Virginia and Kentucky; later into Indiana)

(If I make the Joliet meet, I'm still trying to decide if I want to clinch US 421 in Indiana or US 52 in Indiana on my way home.)

It's been the case certainly since 21 was truncated. That also made 221 and 321 longer than their parent.

By default, all orphaned US routes (166, 266, 199, 138) are currently longer than their parent route

[nexus73]

US 199 wins the battle since the mileage of US 99 is currently zero...LOL!  That's the last of the US x99's these days.

I was wondering about some of the western 3dus routes like 395, 287, etc. Neither of those work.

I'm pretty sure US-730 is longer than US-30

I must have not noticed. What Joliet meet? i'm only 10 miles from there.

In northwestern Pennsylvania, PA 198 is slightly longer than PA 98.

[national highway 1]

I'm pretty sure that AZ 188 is longer than AZ 88.

[corco]

I'm pretty sure that AZ 188 is longer than AZ 88.

Yes! And in fact 188 cannibalized a lot of 88- the stretch from the 88/188 junction to Miami used to be AZ 88

For many, it may depend on whether we want to look at the routes now, or when they were created.  For example, the orphaned routes Takumi mentioned would I suppose technically qualify today, but when these routes were created, the parent route was much longer.

If we want to limit it to cases where both routes still exist, this would also apply to US 191.  Today, US 191 stretches from Mexico to Canada, and is about ten times longer than US 91.  However, in its heyday, US 91 was almost border-to-border, and according to usends.com, US 191 started out at only 125 miles from Idaho to Yellowstone.

I'm pretty sure that was a joke.

US 491 is also longer than US 91, by about 20 miles. By the time 491 came into existence, 91 had already been truncated.

And, 191 was almost completely redefined on its southern extent, especially south of Yellowstone, and doesn't intersect 91 any more. It kind of became 87-1/2 because virtually all of it is between 85 and 89.

I'll agree that it fits according to the letter of the law, but functionally, I think you'd have to say that 191 is 491's parent, not 91, particularly given the second sentence of your post.

US 491's parent is really US 66, who are we kidding.

US 281 is longer than US 81.

True, and I had almost added that to the post. Another route like that is US 701, which I consider a child of US 301 rather than US 1, although it is tangentially connected to 1 via 301 or 501.

So does that make 491 and 701 "grandchildren" routes?
