Multi-state routes and why they exist

[NE2]

I recently found out that at least one of these was a new-wave auto trail from the 1950s. I'm going to try to figure out if there were any others like this, or if all the others were just DOTs playing nice or historic reasons. [I'm not including New England, which was probably all either old New England routes or being nice]

[bugo]

Because they bip.

I'd be curious about how PA 272 lines up with MD 272 for two completely different reasons - the x72 routes in PA and the 27x routes in MD.

[Roadsguy]

PA and DE 100 have been broken up since 2003 when PA 100 was rerouted onto the previously unnumbered expressway connector to end at US 202. DE 100 just disappears at the state line now.

[Mapmikey]

SC and NC changed routes to match numbers across the board in 1937-38.
It looks like GA may have done the same with its neighbors in the 1941-42 timeframe
VA did the same with all its neighbors in 1940.

SC 17 was renumbered in 1928 because of US 17 being in SC.  All other US route/state number duplications were eliminated then as well...

[Quillz]

It's not a multi-state route, but CA-139 and OR-39 connect to one another. Maybe a psuedo-MSR?

[DandyDan]

I recently found out that at least one of these was a new-wave auto trail from the 1950s.

*AR-MO 5: AR numbered to match
post in progress

Should read:
*AR-MO-IA 5: AR and IA numbered to match

*IL-IA-NE 64: IL 64 extended over IL 77, with IA 117 changed to match; later extended over IA 88-7; unrelated NE 64 later extended east over NE 93-130 to meet

I don't believe 64 ever made it to the Missouri River on either side of the Iowa-Nebraska border.

[Takumi]

I'm curious as to why VA/NC 170 was changed to an extended 168 in 1958. Was it to have a continuous route number from the then-new Hampton Roads Bridge-Tunnel to NC?

[TheStranger]

I'm surprised no mention yet of (TX)-OK-KS-NE 99, of which the Texas part became US 377 (while half of the Oklahoma section is a concurrency of 377 and 99).

[hbelkins]

Was there at one time a ferry linking the end of KY 80 across the Mississippi River to MO 80?

[NE2]

I don't believe 64 ever made it to the Missouri River on either side of the Iowa-Nebraska border.

Old Iowa DOT maps show that if it didn't, it got pretty damn close.

[drummer_evans_aki]

Idaho, Montana, North Dakota, Minnesota Route 200

Yes: http://bridgehunter.com/mo/mississippi/belmont-ferry/

Idaho, Montana, North Dakota, Minnesota Route 200

Already listed...

[US71]

*AR-MO 37: AR 47 probably changed to match when the rest became US 62

Not quite. 47 changed to 37 in the early-mid 1980's

*CO-KS-MO 96: history of CO-KS unclear (both existed in 1926); MO 16 changed to match realignment over KS 26

No longer continuous. MO 96 now ends at MO 171 near Carl Junction.

[NE2]

*AR-MO 37: AR 47 probably changed to match when the rest became US 62

Not quite. 47 changed to 37 in the early-mid 1980's

You're right - 47 was dropped from some of the early state maps.

[JCinSummerfield]

OH & WV 618 come close

[Alps]

It's not a multi-state route, but CA-139 and OR-39 connect to one another. Maybe a psuedo-MSR?

Reminds me of NJ-NY 84. When I-84 came to NY, it renumbered NY 84 to 284 - because the two were so close together, as opposed to it being a general rule. NJ obediently renumbered its own 84 to 284. There aren't many in NJ - 17 with NY and 48 with DE are the other two that come to mind, and 48 I believe is a case where DE followed NJ. There's also 439 and 440, very clearly numbered by NJ to match NY. And hell, that's all of them.

[NE2]

Crap, I forgot DE-NJ 48. It definitely was numbered because of the ferry: http://www.deldot.gov/archaeology/historic_pres/historic_highway_maps/pdf/cd_008.pdf

PS: check out the complicated history of 284.

[US71]

There was KS-MO 57 until MO 57 became 171.
Later K-57 east of US 69 was renumbered as K-171

Old US 66 is now MO 66, becomes K-66

[NE2]

There was KS-MO 57 until MO 57 became 171.

Both already listed.

I'm curious as to why VA/NC 170 was changed to an extended 168 in 1958. Was it to have a continuous route number from the then-new Hampton Roads Bridge-Tunnel to NC?

This is the exact citation from the Nov 1957 CTB:

ROUTE 168 IS DESIGNATED via the Bridge-Tunnel crossing Hampton Roads and through Norfolk and South Norfolk replacing present Route 170, and whereas due to this routing of Route 168 through the cities it is also practicable to continue Route 168 over present Route 170 in Norfolk County to the North Carolina Line, and whereas present Route 170 continuing from Virginia into North Carolina has been approved by the North CAROLINA HIGHWAY Commission on November 4, 1957 for its designation as Route 168; NOW, THEREFORE, BE IT RESOLVED, that present Route 170 in Norfolk County be renumbered to carry Route number 168, from the south corporate limits of south Norfolk south to the North Carolina State Line; also the portion of present Route 168 leading from the east corpor ate limits of Norfolk east to an intersection with Route 60. in Princess Anne County be renumbered to carry Route 170. Motion carried

This suggests that your theory (my guess is you mean headed for the Outer Banks area and not just NC which was already accomplished by US 17) has merit though it is not explicitly stated why NC and VA agreed to do this.  One bit of evidence against the theory is that NC 168 headed southwest to Elizabeth City and not towards the beach until 1979.

[roadman65]

DE 71and MD 71 (Now US 301) used to be one route before the Bay Bridge was built.  I do not know the history of the two, but indeed DE 71 did not head south to end at US 13  in Townsend, but followed what is now US 301 SW if Middletown even long after MD 71 was decommissioned to be re-touted US 301.  DE 896 was originally to Townsend via present day DE 71 then, and the road to Boyds Corner that is now the home stretch for DE 896 was previously unnumbered.

[corco]

WA/ID 128- Idaho commissioned and numbered to match 1990

[Road Hog]

OK-TX 91 is the old route of U.S. 75 and farther north, the U.S. 69-75 concurrency, before the present freeway was finished. It crosses the Red River over Denison Dam, which was built during World War II.

[kphoger]

*CO-KS-MO 96: history of CO-KS unclear (both existed in 1926); MO 16 changed to match realignment over KS 26

No longer continuous. MO 96 now ends at MO 171 near Carl Junction.

Besides which, KS-96 now ends at US-54/400 in Wichita.
