Old Alignments of 1 or 2 digit routes with 3di style numbering

[mightyace]

I'm starting this as I mentioned in the Old alignments as multiples/divisor routes thread about TN 243 being an old alignment of US 43.

Please post any  1 or 2 digit routes like that have become a 3 digit "child" numbering.

Mississippi's old US routes are almost always numbered as state route 1xx.  For example, MS-145 is an old US-45 alignment.  The only exception I can think of offhand is MS-245, which is an old alignment of Alternate US-45.

I'm not sure what they'd do if they built a bypass using US-278, which is their only three-digit US route.  They'd probably make it MS-378.

Since A-30 changed alignments before even being completed, the old alignments were renumbered as such this year : A-530 (entire Valleyfield section), A-730 (St-Constant between current A-30 and QC-132) and A-930 (Delson, QC-132 to current exit 99, includes A-15 interchange).

Probably not intentional, but a new KY 30 alignment is now in use and the old route is called KY 3630.

WV 152 is an old route of US 52.

MN 361 is part of old US 61.

Minnesota has also done this with some state routes. Part of what was MN 49 is now MN 149. Likewise MN 56 and 156.

I think for a time part of old MN 3 was MN 103.

1. WI 253 is old US 53 before the freeway was built.
2. WI 241 (27th St) and WI 341 (Miller Park Way) are old US 41 before they moved 41 onto I-94 near Milwaukee.
3. It would not surprise me if part of WI 145 had been US 45 before the Zoo Freeway was built.
4. IL 267 i believe was an old alignment for US 67 south of Jacksonville IL.  Rich Carlson would probably know better than I on this one.

A part of old US 35 near Washington Court House, Ohio is now OH 435, probably because OH 435 provides the only connection between current US 35 and I-71.

I'm not sure what they'd do if they built a bypass using US-278, which is their only three-digit US route.  They'd probably make it MS-378.

As I understand it, the old alignment will not remain a state route.  If it does, it'll likely get a MS 7xx number.

I think for a time part of old MN 3 was MN 103.

Not quite.  MN 103 was used in the early 90s for completed parts of the Lafayette Freeway south of I-494.  It became today's US 52 in the mid-90s once the freeway was completed to MN 55.  It was so numbered because it was an extended spur of MN 3 (which at the time followed the Lafayette Freeway north of I-494), not because it replaced MN 3.

US-51 in Illinois has two: IL-251 and IL-351.

3. It would not surprise me if part of WI 145 had been US 45 before the Zoo Freeway was built.

Nah, US 45 has always dropped south once entering Milwaukee County ever since US 45 was added to Wisconsin.  Before the freeways, US 45 stuck to Mayfair Rd/108th St/Lovers Lane Rd (depending on the municipality) through Milwaukee County to join US 41 at Appleton Ave.  WI 145 in it's current form has been sort of a "spur route" like WI 310 or WI 312.

CA-69 became CA-245.

California also uses 3xx for old alignments. So CA-330 and CA-371 are old alignments of both the former CA-30 (current CA-210, eventually will be I-210) and CA-71 (truncated to CA-91 at some point).

Other examples are a portion of CA-17 becoming I-880, CA-21 becoming I-680 and CA-31 becoming I-215. However, I'm not sure if these would count because an Interstate number is always an "upgrade" over a state route number, regardless of the number of digits.

[mightyace]

^^^

CA 30 to 330 and CA 71 to CA 371 count.

CA 69 to 245, CA 17 to I-880, CA 21 to I-689 and CA 31 to I-215 don't count as the last two digits aren't the same.

Portions of US 33 in Indiana became SR 933 after US 33 was truncated in Elkhart.

[US71]

Please post any  1 or 2 digit routes like that have become a 3 digit "child" numbering.

MO 571, MO 371

MO 366, MO 266

MO 350

MO 740

MO 269

MO 765

MO 763, MO 163

IOWA 471


AR 471 (now posted US 71B)

AR 367, AR 267

AR 463

AR 365 (US 65)



There is also an AR 164, but it is NOT a former alignment of US 64.

[TheStranger]

In addition to the aforementioned 330 and 371 examples for California, the short north-south connector through Concord that was built as Route 24 became legislative Route 242 in 1964, followed by that route being signed (with 24 being truncated to Walnut Creek) in the late 1980s.

[Duke87]

First example that jumps to mind is NJ 124 = old NJ 24.

[Hot Rod Hootenanny]

In Ohio...
309 formerly US 30 S from Mansfield to Delphos
412 formerly Oh 12 (before it was truncated) from Fremont to Sandusky
416 formerly Oh 16 (before it too was truncated) in Tuscawarus County
421 formerly US 42 through Lodi (SW Medina Co. near I-71-76 interchange)
423 formerly US 23 in Marion County
424 formerly US 24 from Defiance to Napoleon
430 formerly US 30 from Mansfield to Mifflin
435 formerly US 35 on either side of I-71 betweeen Xenia and Washington C.H.
444 (sort of) formerly Oh 4 east of Dayton (some of the original routing was abandoned for Wright-Patterson AFB)
446 formerly Oh 14 (not Oh 46) bypass of Canfield (SW of Youngstown)
450 is NOT a former alignment of US 50, east of Cincy, but an aborted rerouting for US 50
550 formerly Alt US 50 (and originally US 50 N) between Athens and Marietta
735 formerly US 35 near Galopolis
800 formerly Oh 8 from Canton to Ely (Ohio River)
821 formerly US 21 from Byesville (near Cambridge) to Marietta
833 formerly US 33 around Pomeroy

And special mention to former Oh 440 which is what former and current US 40 was signed as in the 1960s when sections of I-70 were completed (and of which US 40 was "rerouted" onto)

Rhode Island:

238 is an old alignment of 138
246 is an old alignment of 146
214 could be an old alignment of 114...
33 is an old alignment of 3, I believe.

[WNYroadgeek]

US 15 from Painted Post to Wayland > NY 415

[cu2010]

also, NY17 -> NY417.

Though, of course, with I-86 eating up 17, could 417 be renumbered back to 17?

[WillWeaverRVA]

I'm fairly sure VA 457 is a renumbering of an old alignment of VA 57.

[Alps]

NJ 120 = former 20, once it was clear it would never connect to the other piece(s)
NJ 122 = original US 22, later ALT 22 after a bypass was built in the late 20s/early 30s
NJ 138 = former 38, once it was clear it would never connect to the other piece
NJ 143 = former 43, though the original 43 is now US 30 (this was built as a like-numbered spur)
NJ 187 = former 87
Honorable mention: NJ 324 is old US 322. You can see what they did there.

[FreewayDan]

In South Texas, SH 359 was once part of US 59.  While in DFW, SH 180 was part of US 80.

Connecticut loves to "rhyme" with a former numbering. Here's what comes to mind:
Old alignments of CT 72: CT 272, CT 372, SR 572
CT 17: SR 517
CT 35A: SR 835
CT 39: SR 839
CT 67: SR 867 (via CT 67A)
CT 84: CT 184 (via CT 95)
CT 87 was to become CT 287, but the conflicting interstate (87) became 684 instead

These are 3di to 3di renumberings: tangentially related to the thread:
CT 109: CT 209
US 202: CT 302
SR 905: CT 305
SR 909: CT 309
(many more examples involving secret routes: almost every signed route above 220 is based on a rhyming secret route)

[national highway 1]

Old US 85 in Las Cruces NM-it has become NM 185.
Historic US 66 in Missouri has become MO 66, MO 266 & MO 366 (no 166 because of US 166)
