Nope.  PA does not duplicate interstate and state routes unless created by a renumbering.  PA has I-90 (yes, it's almost 400 miles away, but it's there).

Thanks for pointing that out. On Google Maps the 90 number is still there for the PA section of the road but there is not a real PA-90 route there.  :-/

I seem to be picking up a theme here. States that organize their state highway numbers based on a grid (like Florida, Indiana, and South Dakota) or by numerical ranges based on the county (like Nevada) tend not to have highways that keep their numbers across the state line - which I suppose makes sense, given that those states are all doing their own thing, presumably without regard to what numbers the neighboring states have given the roads. In your opinion, does my assessment seem right?

Depends.  That state could be doing its own thing, but the neighboring states might still strive for continuity.  Or it might not even be a clear either-or situation.

For an interesting example, Kansas has this cool thing where the three westernmost N-S state highways are  23—25—27.  Oklahoma doesn't do the same thing, yet they carried the 23 number across into Oklahoma anyway.  Even more interestingly, though, the two routes didn't immediately connect to each other, as K-23's terminus was short of the state line, and Kansas extended K-23 in a joint decisions with Oklahoma for the purpose of route number continuity.

Quote from: Oklahoma Department of Highways – Office of the Director – 14-DEC-1959
HIGHWAY ROUTING AND NUMBERING NOTES FROM JOINT MEETING, OKLAHOMA AND KANSAS HIGHWAY COMMISSIONS AT WICHITA, KANSAS ON FRIDAY, DECEMBER 11, 1959

4.  In Meade County, Kansas, Kansas route 23 will be swung southwesterly to enter Oklahoma in line with SH 23, northeast of Forgan.  The route number (23) will be common to both states;  it will be carried into Texas south of Elmwood in Beaver County.  The alignment of this Kansas connection is properly shown on the 1959 Oklahoma Highway map.

And, at first glance, it might appear that they didn't likewise care about route number continuity with K-25, considering they kept the OK-136 number.  But actually, when you dig into it, you find that they actually had a reason for that too.

Quote
3.  Kansas is planning a new route, Kansas 25 to run south from Feterite in Stephens County, straight to the intersection north of Guymon.  Although this route will be SH 25 in Kansas, it will remain SH 136 in Oklahoma, since the connecting route in Texas is numbered 136.
Keep right except to pass.  Yes.  You.

Out of the 24 current state highways in Iowa that cross a border, 16 of them keep their number in the neighboring state (So, 2/3 of them). It makes sense for it to be a fairly high portion of highways, since Iowa has historically put a heavy emphasis on route continuity with neighboring states (To the point where the original establishment of Iowa's highway system in 1920 prioritized route continuity over creating a numbering system).
There's also IA 92 and NE 92, part of the very important multi-state route from Torrington, WY to La Moille, IL.

SD:

SD-MT:
SD 20 to MT S-328

SD-WY:

Yeah seems legit, WY numbers their road by county as well and there's really no carryover there either except for WY/MT 59, which just so happens to be in the "50-69" county in WY (Campbell).

Given that Oklahoma has never had much of a state route numbering system, we've been one of the most accommodating states when it comes to renumbering to match surrounding states. We've gone to extremes to do this, such as duplicating numbers that already exist (37, 4) and renumbering routes that extend halfway across the state (152, which was originally 41 and got renumbered to match TX-152). We even renumbered the only state highway that connects with New Mexico to match theirs, 325...and then they renumbered theirs to 456. Jerks.

The current count for Nevada may be four, but historically there were two more:
  • Present-day SR 225 was numbered SR 51 prior to 1976, so there was NV 51/ID 51. (Note that Nevada changed what had been a portion of SR 11 and the entirety of SR 43 to create SR 51 circa 1964-1965, presumably to match Idaho. SR 51 was changed to SR 225 circa 1976 due to the statewide renumbering.)
  • Present-day SR 233 was numbered SR 30 prior to 1976, so there was NV 30/UT 30. (On the Utah side, the route was previously UT 70 and they changed to match Nevada circa 1966. Nevada changed circa 1976 due to the statewide renumbering.)

    Yes, to an extent.

    At least for Nevada, it is interesting that three of the four numbers currently carried into adjoining states are on route numbers that existed prior to the 1976 state highway renumbering: 28, 88 & 140. Given the county-clustering number method that was adopted during the renumbering, NDOT specifically retained these three pre-1976 numbers despite the numbers not fitting in to the new cluster scheme (although SR 140 was originally planned to become SR 291 during renumbering).

    So that shows there was some desire for some route number continuity with other states on Nevada's part. SR 28 & SR 88 made sense given the regional travel around the Lake Tahoe region, and SR 140 was the number advocated for the "Winnemucca to the Sea" highway. I suppose there wasn't as much tourism concern with 30/233 and 51/225 then, because otherwise it would have been simple enough to retain those numbers post-renumbering as well...

See, in Utah the general rule is that anything big has a low number (2-digit, generally), but the opposite is not necessarily true. There are seven 1/2-digit routes less than two miles long, and SR 93 barely breaks a quarter mile. So for me, putting a high number on some long highway is far weirder than a low number on a short one.

Most of that is due to deletion and reassignment of those lower numbers, but there are some holdovers from the original weak number clustering scheme which more or less increased numbers from SW to NE. SR 17, 22, and 25 are all original routes that seem like they should belong on bigger/longer roads.

What really should be how many roads keep their number out of the many that cross a border to those that don't excluding New England of course as almost all numbers keep continuity.

In NJ surprisingly there are only a few along the long stretch of Delaware River with PA. NY has four ( five it you count Route 440 twice) but many other roads cross but change.  NY 45 is most Bizarre as it don't become anything but a named road in NJ.  Some NJ 500 routes become named roads in NY and a few become NY state numbers like CR 501, 503, and 505 as well as CR 511 with the rest being interstate or US routes or NJ 495 that is questionable being NY 495 isn't signed in Manhattan.   NJ 23 becomes County in NY the opposite of other cross state roads.

Maybe a ratio thread should be created to show the percentage.

It seems strange that a state would use a highway number like 35 for such a short highway.

MN 20 is another such road unworthy of a low number, running just 7 miles from MN 19 to MN 50.

This could change if MnDOT ever decides to reroute US 61 onto 316.  My read of the Constitutional Route descriptions suggests that they'd have to keep the leg of existing 61 between 50 and Hastings on the system.

technically, WA 433 physically enters Oregon and ends where the roadway makes land fall just north of the US 30 interchange

Wait, so WSDOT somehow maintains the ramps leading up to US 30?
ODOT has the ramps and the road on the physical Oregon soil, no ORH number or all part of ORH 92/US 30 maintanence. WA 433 is the bridge deck itself on the Oregon side.
