Some 3-digit US Routes wander away from their parent route and enter a state without their parent.
Here are some examples:
US 666 went through CO & UT where US 66 did not.
US 491 goes through CO & NM
US 550 goes through NM, where US 50 doesn't
US 830 ran across the Columbia River across from US 30 in WA where US 30 stayed in OR.
US 385 runs through NE and OK, where US 85 travels through Cheyenne and Denver and then sticks to I-25 and I-10 till El Paso
Does anyone know of any other examples?
US 158 and US 311, which are only in NC, which their parents do not enter.
The daughter routes of US 21: US 221 enters Florida, US 321 and US 421 enter Tennessee. Only US 521 does not stray away from US 21.
US 178 goes into NC and US 278 goes into Arkansas.
-US 206 goes into New Jersey where US 6 does not.
-US 202 goes into MA, CT, NJ, PA, and DE while US 2 does not.
-US 301 goes into Delaware while US 1 does not.
And most of US 209 is in Pennsylvania, where US 9 does not go.
Technically US-199, but US-99 doesn't exist anymore. When it did, it worked.
US-491 (former US-666) in New Mexico. I don't think US-91 ever did go in NM either.
US-395 in Washington.
US-730 in Washington.
US-195 in Washington.

Similiarly, US 287 cuts across Cimarron County in the panhandle, while it's a near miss with US 87.
Obviously US 220 which with the exception of Pennsylvania and New York is never in a state with its parent as it extends all the way to North Carolina for some reason
US 231 enters Florida; US 31 just misses it by less than a quarter mile.
US 270 enters Kansas, but US 70 does not
US 195 enters Washington, US 95 never enters Washington
US 159 enters Nebraska, but US 59 does not
US 219 enters NY, but US 19 doesn't.
Since 3-digit US routes can be hundreds of miles long (unlike 3di's), there must be an enormous number of examples, really....

220 is also like the former US 104 in that...it doesn't even touch its parent at all!
US 151 enters Iowa, but US 51 does not.
US 167 enters Louisiana but US 67 doesn't.
We have a few in Kentucky...
US 119
US 150
US 421
West Virginia, off the top of my head, has only US 220.
US 191 enters WY, while US 91 went through into ID.
US 275 spends 26 mi in MO.
US 310 heads south into WY.
US 340 enters VA, and US 240 used to enter DC
Old US 170 (now US 29) also entered VA
US 222 enters MD, while US 522 enters MD, & VA (US 22 cuts across the northern tip of WV)
If we're including truncations and deletions that have occurred over the years, then US-199 is in California and Oregon while US-99 no longer is. US-395 travels through Oregon and Washington while US-95 does not.

Regarding this, is there some actual rule on 3di length? 3dus tend to be quite long for some reason, while the longest 3di is only 132 miles long. But there's no actual rule on length, right? Couldn't there theoretically be a very long 3di somewhere?

Interestingly, I would say that the US routes seem to have much stricter rules on length now (i.e. no single-state routes under 300 miles will be created, any US route that doesn't follow that length minimum now has to cross state lines) than the Interstates do (I-86 west, I-97, the old I-86 east).

US 95 does enter Oregon.
US 160 enters KS & CO but US 60 stays in OK, TX and NM. US 160 used to go into UT until 1970 before being rerouted SW past Four Corners into AZ.
US 224 strays into PA, while US 24 curves north into MI.
US 441 enters NC, while historic US 241 (II) went into AL
US 271 runs 3 miles away from its parent, US 71 by entering OK.
US-219 goes into MD while US-19 doesn't.

Agreed.
QuoteRegarding this, is there some actual rule on 3di length?
Just what Mr. Sampang mentioned...but even AASHTO's policies on US routes have been "shortchanged" (witness the recent extension of the aforementioned US 311).
Back to the original topic, three that haven't been mentioned yet are US 136 in Iowa, US 212 in Wyoming, and US 218 in Minnesota.

Don't forget about its non-important brother, US 331.
US 271 crosses into Oklahoma and Texas.
US 71 barely grazes Texas and isn't in OK at all.
US 421 in Indiana
US 127 in Michigan (though US 27 used to go there)
Okay, I'll take a stab at a few states I know fairly well:
Pennsylvania - 202, 209, the former 309 (now Pa. 309), 224.
New Jersey - 202, 206.
Delaware - 202 again.
Maryland - 219, 220.
While we're at it, is there a state other than Rhode Island (D.C., Alaska, Hawaii don't count) that has no 3dus?
Washington- 730, 195, 395
Wyoming- 191, 212, 310
Idaho- none
Idaho is very close on having no 3duses- it just has that quarter mile stretch of US-195

But it DID touch US-120 in Lock Haven until it was decommissioned...but then again, I don't think US 120 ever made it to US 20 did it?
US 123 enters South Carolina, US 23 does not.

Early in its history and for only a short time, US 120 ran from Erie to Philadelphia (so it did touch US 20).
US 275 in Missouri
Does US 412 count or US 425 ?
I'd doubt it, since they are illegitimate routes
Old U.S. Route 611 technically entered Jersey for a time. 11 never did.
US-666 made it to Colorado and Utah. Now, US-491 makes it to New Mexico.

US 466 in that vein made a stop in Nevada on its way from Barstow to Kingman - a state US 66 never entered.
