3-Digit US Routes that Travel Through States that the "Parent" Route Does Not

[getemngo]

I would wager that more 3dus routes enter states their parents don't than not.  It's one of the reasons I'm not very fond of the US route system.  If you're going to make the number essentially random, then don't try to claim there's a system.

I don't think more than half of all 3dus routes do, no. When making my list, I went through about half the states, and the number felt closer to 25%. For example, US 301 is the only instance out of the six x01 routes. There are no instances in states as big as California, Illinois, Wisconsin, or Ohio.

But I do agree that the US system is a mess. I wish every 3dus route was either a loop or spur of its parent, not a highway that happens to intersect its parent somewhere, or one that no longer connects to its parent at all. (Does this mean its parent has disowned it? )

It'd be wonderful if 3dus were numbered in the same way as 3di's, or at minimum, all decommissionings or renumberings favored the 1- or 2-digit route. When I-94 came to Michigan, US 12 stayed and US 112 was decommissioned, even though the opposite would have been way less of a headache for AASHTO. I'd like to see more of that effort.

I wouldn't be suprised if there are 3dus routes that are longer than their parents.

Found a thread on it.

US 202 is the king of this thread.

or one that no longer connects to its parent at all. (Does this mean its parent has disowned it? )

Or never did in the first place.

IIRC, the original 1925 and 1926 plans treated 3duses more like 3dis.  3duses were short, connecting routes off the main 2duses.  It was only later, during the 1930s and 1940s that the system got to be fucked up.  It should never have been allowed to get that way, IMHO.

The problem is that the system was expanding too much for that to work. Most state highway systems had similar issues with early numbering schemes.

Pennsylvania was the first to blur the lines and twerk 3duses all over the place.

Former US-460 in Indiana. I almost said Illinois as well, but I remembered that 60 enters Illinois for about a mile in Cairo.

[DandyDan]

US 159 in Nebraska

[US71]

Would US 166 MO/KS count since US 66 no longer exists?  Also US 266 in OK.

[OracleUsr]

US 221 in Georgia and Florida

[cpzilliacus]

Would US 166 MO/KS count since US 66 no longer exists?  Also US 266 in OK.

Also U.S. 199 in California and Oregon.

3-Digit US Routes That Meet Criteria That Would Be Impossible For Them Not To Meet

[roadman65]

We should do another topic of 3 digit routes that enter a state that it does not at all touch its parent. 

If so you would have US 319 in Florida.
US 222 in PA.
US 206 in PA (US 206 no longer meets its parent, although it does come within a mile)
US 220 in PA
US 219 in PA
US 119 in PA

It seems that PA leads em all if this was the case.

US 206 and 222 doesn't count, because 6 and 22 are both in PA. Also, US 19 does go into PA, so 219 and 119 don't count.

However the 3Dus does not touch its parent within the state, which is a bit off topic of the thread but still an interesting point.

I know its off topic which the first line suggests.  I was merely suggesting that a new topic could be discussed.  As far as deviation goes, I am not the first person to be one to do so, as many have done so and even gotten so far off topic it is unbelievable!

Read the first line.  I was merely suggesting that it would be interesting to start a new topic that is almost related.  Of course I know all of those I mentioned are together in the same state which is my point of another  topic that would also be interesting.

[dgolub]

This is very much the case for US 202, US 206, and US 209, although someone mentioned all of them somewhere along the way.  Also, US 301 in Delaware, which I don't think anyone mentioned.

[froggie]

I don't think US 301 DE falls under what roadman suggested, since US 1 never enters Delaware.

One that would qualify, though, is US 212 in MN, SD, and MT.  'Course it helps that US 212 NEVER touches its parent.

I saw that, but I was skimming the thread and just thought you were talking to someone else who was doing that, and then you were starting to list examples for this thread. Next time I'll re-read the post.

That is okay.  We all do not read many posts correctly, including myself.  I cannot tell you how many times I got egg on my face for misreading.

US 127 does not touch US 27 in Kentucky.

US 431 does not touch US 31 in Kentucky.

US 231 also does not touch US 31 in Kentucky, but it does touch US 31E and US 31W.

US 641 does not touch US 41 in Kentucky (or at all, for that matter).

[jp the roadgeek]

Add MA to the US 202 list
US 222 in MD
US 101 in CA/OR/WA

[SD Mapman]

What about US 310 in WY/MT?
This fits the original topic and the new spin-off topic.

U.S. 422

US 195 and 395 in Washington. US 191 in Wyoming and Montana (though 91 used to go through MT). US 730 in Washington.

[NE2]

US 95 used to touch Washington.
