US Routes that have no junctions with another US route within a state.

[roadman65]

US 212 travels across the NE Corner of Wyoming without a junction of another US route.  In fact it does not intersect any other numbered route whether Interstate or State here  for its 20 mile appearence  nor so as it does enter Wyoming again several hundred miles to the west at Yellowstone, but  at least here it  at least does connect with other roads that are not part of the Interstate or other US or state numbered roads.

Are there any others that do this?

[xonhulu]

US 95 does this in Oregon.  It only junctions with OR 78 in the 121 miles it's in the state.

I don't think US 95 junctions with any US Highways in CA or AZ, either, thanks to US 66, 60/70, and 80 being truncated to points further east.  US 50 also no longer junctions with any US Routes in CA.

Since I came up with 4 more examples in only 3 states, I have a feeling there are quite a few examples of US Highways that don't have junctions with other US Hwys in a state.

Yes, it happens a lot.  A quick grep, again on CHM data for US highways, gives me 61 such examples.  I didn't check in detail for possible errors in the list (I just looked for waypoints in each US highway that start with "US", if I don't find one, it doesn't cross another US highway).  The most likely cases this does not consider are those of a US highway crossing a US highway that's concurrent with an interstate.  In such cases, the interstate's name would be used for the waypoint.  I'm guessing this wouldn't eliminate more than a handful of the 61 matches anyway.

Good.

I'll do whatever I please.  If you want roadman65 polluting the forum with a needless thread that doesn't actually allow for discussion, a thread that will die in a week and will be necro'd twice in the next six months by roadman65, be my guest.

PS - if you actually did any moderation, there wouldn't be so much shit here.

[Kacie Jane]

Wow, seriously?  Do yourself a favor.  Take a look around the internet.  Compare the so-called shit here to the actual shit you find virtually anywhere else.  If you don't like the shit here and the moderation or lack thereof, then please feel free to take your shit elsewhere.

Damn, man, and I thought I was being combative over the IDiOT thing.

Chill.  It's a topic, and if you don't like it, don't read it and don't post in it.  So what if it gets necro'ed.  Why should you care?  I don't.  There's bigger things to worry about than a thread like this.

The Florence, WI section of US 2/141 does not intersect any other US highway in Wisconsin.

InterstateNG, the moderators were chosen as moderators for a reason - to keep order on the site. If you don't feel like we're doing a good enough job on something, feel free to shoot us a message, or report the post in question. Posts like yours are NOT the correct course of action. We do do moderation, this thread is no more needless than most other threads in here (this is an internet forum - if you don't find the topic necessary or interesting, don't read it!), and if you think you can do whatever you please, you won't last very long on any one website.

There is no point in any personal attacks or arguing. Either discuss the intended topic or this thread will be locked. roadman65, that goes for you too.

And for the record, this is a fairly interesting idea that I don't recall ever having been discussed before.

Nearly every U.S. route in California. All I could think of for junctions was 101 at 199. Although the OP specified junction with any interstate route as well, the thread seemed to morph to confining consideration to U.S. routes.

[english si]

I didn't check in detail for possible errors in the list (I just looked for waypoints in each US highway that start with "US", if I don't find one, it doesn't cross another US highway).

There's quite a bit of scope for false positives there - if the waypoint label is an exit number, or the intersecting US route is concurrent with an interstate.

BTW, here are the routes I got from the CHM data.  Again, some are probably not quite right.  I debunked one in the list below, feel free to debunk others.  Looking now at this list, I see it also may be affected in some cases by the fact that a highway might be plotted in multiple segments (if it enters a state more than once).  Perhaps the most surprising to me is that 4 of the 8 US highways in Massachusetts don't intersect another US highway.

I debunked one in the list below, feel free to debunk others.

I also thought of US 395's northern segment in CA, but since its southern segment intersects US 6, I didn't list it.  The topic sounded like it wanted the entire route in that state considered, not just individual segments.

Probably a minor point of discussion, as there aren't that many examples of US Routes leaving and re-entering a state.  I'm thinking maybe a dozen examples, tops?

[Jim]

I'm seeing 22 examples of US highways that are in 2 segments within one state, and 4 examples of US highways that are in 3 segments within one state, where segments are broken up by crossing over a state line and back.

Edit: make that 21 examples in 2 segments for state line crossings.  US 49 in MS shows up that way, but it's broken up because it splits into 49W and 49E for a while.

[roadman65]

US 1 in MA.  Co-signed with MA 3, but never intersects US 3

Actually this is a great find!  Never thought of it as I forgot that US 20 ends short of US 1 in Boston and US 3 ends in Cambridge.  US 6 and US 44 the other two E-W routes intersect in Rhode Island.

US 71 goes from Arkansas to Texas back to Arkansas.  US 271 used to go from Arkansas to Oklahoma to Arkansas, but this was changed many years ago.

[hbelkins]

US 40 in West Virginia doesn't count. It actually crosses into Ohio while co-signed with US 250.
