State Routes signed like 3di

[ilpt4u]

In a more literal sense, IN 265 and KY 841 are State Routes signed on a 3di - since AASHTO approved the East End Crossing in the Louisville area to be a part of I-265, yet neither KYTC nor INDOT have added the I-shield to the stretch

Louisiana's system doesn't do this either. There is a LA 471 that branches off of US 71 near Colfax, but I think it is coincidental. 471 is an old routing of US 167, but that would have been before the 1956 renumbering.

I am beginning to think that TN SSR 243 is actually more coincidental in numbering than actually a supplanted routing number for the old US 43.  If you look in Maury County you will also see that there is a SSR 245, SSR 246 and SSR 247 in the vicinity as well.

LA 3049 is, I suspect, old US 71 north of Shreveport, but many years ago before anyone heard of I-49.

You are correct. There are many other state routes that are old alignments of US 71. You can usually tell if they are parallel routes or are small loops. And especially if they are called Jefferson Hwy.

I don't know if anybody here has mentioned anything about MO-744, just south of I-44 in Springfield, MO-765 in Sedalia, which is just east of US-65, and MO-759 in St. Joseph, just west of US-59. I guess another example could be the former MO-465 in Branson (before it was decommissioned in March 2020). US-65 through Branson is pretty much an expressway with multiple exit ramps, and MO-465 was also an expressway with two exit ramps, acting sort of as a bypass around Branson.

Yep, already mentioned:

MO-744 (Which is a former alignment of US-66 in Springfield ...

MO-765 in Sedalia, which is just east of US-65, and MO-759 in St. Joseph, just west of US-59.

Neither US-65 nor US-59 is an Interstate, therefore none of those MO- routes are numbered like a 3di.

I don't believe Texas has any, because TxDOT just doesn't work that way.

In Arizona, besides SR 210 mentioned previously, there is one that partially qualifies. SR 51 was originally planned to be numbered as either I-510 or SR 510, and they chopped off the zero. Quite a few that can be included if extended to 3dus routes. SR 189 and SR 289 are spurs of what used to be US 89. SR 195 is a spur of US 95. SR 260 is a double-sided spur of US 60. SR 266 and SR 366 are spurs of old US 666 (now US 191). SR 389 is a spur of US 89A.

I think it's coincidence, but Lubbock has a Texas State Spur 327 that connects from US-62 to Texas State Loop 289.  Loop 289 is a complete freeway loop, the only loop I can think of in Texas that is 100% a freeway and not an interstate loop.  If Loop 289 ever got upgraded to a 3di, it would be I-227 possibly, making Spur 327 an candidate for an I-327.

Historically, both I-410 and I-610 were Texas State Loop 410 and Texas State Loop 610 respectively while they were undergoing upgrades to interstate standards in the 60s.  When they were finished, Texas canceled the state highway designations in favor of the interstate numbers.

Loop 289 is a complete freeway loop, the only loop I can think of in Texas that is 100% a freeway and not an interstate loop.

Is Loop 1 not entirely freeway? Granted that's not a physical "loop", but it's still a designated loop state highway.

Everyone knows Loop 1 isn't a loop.  I am referring to 360 degree freeway loops regardless of classification.  Texas has a lot of loops that don't even have the Texas State Loop classification.
