Highways with the same number near state lines

[bugo]

There are several instances of highways near state lines with highways with the state number near the same state line in another state. Here are a few examples.

US 59/AR 59 in West Siloam Springs, OK and Siloam Springs, AR. These two highways are about 2 miles apart along US 412. Locals call US 59 "Oklahoma 59" and AR 59 "Arkansas 59".

US 89 and WY 89 near Geneva. ID. These two highways are about 1 mile apart. ID 61 splits off of US 89, heads south and quickly becomes WY 89. WY 89 parallels the state line then heads into Utah and becomes UT 30 which connects to US 89.

US 30 and UT 30. US 30 meets WY 89 which heads west and becomes UT 30 in about 12 miles. Unlike the US/WY 89 example, US 30 and UT 30 do not come close to meeting to the west.

KS 7/MO 7. These two highways run through the Kansas City metro and are about 25 miles apart as the crow flies at their closest points. These are two widely separate highways and are unrelated.

MN 11/ON 11. These highways parallel the Rainy River and the international boundary and in places are less than a mile apart. Since they are in different countries, I doubt there is a whole lot of confusion.

In the US/AR 59 and the US/WY 89 examples, were there disputes to which side of the border the US highway would follow, and did the "losing" state number their highway out of spite?

In a similar vein to MN/ON 11, I-2 and Mexico 2 .

I-265 IN and I-265 KY, in the same metro area (Louisville). I thought they had already condensed into a single designation, but it appears this is not the case yet.

Any pair of state routes that keep its number crossing the state line.

There's I-35 and WI 35 in Duluth-Superior.

I always thought it was interesting that IA 12 and NE 12 both go towards Sioux City. I personally think if the fictional US 77 extension up IA-MN 60 was created for real that the current US 77 north of US 20 be called NE-IA 12. Iowa would have to come up with another unsigned number for Business US 20, but there is an infinity of them.

In the historical record, IA 105 and MN 105 had less than 10 miles between them. I also believe IA 254 and MN 254 were similar.

CT 20 and US 20 (in Massachusetts).
NH 236 and ME 236 (no, they're not the same route).

EDIT:

MA 101 and NH 101
US 7 and NY 7

IA and MN-254 were intended to (if they actually didn't at some point) meet. I had originally posted otherwise, but I'm pretty sure I was wrong, upon further research.

CT 20 and US 20 (in Massachusetts)

One of the more unusual banners I've come across...

[MNHighwayMan]

Clearly they're just indicating the route one takes to Church 20.

CT 20 and US 20 (in Massachusetts).
NH 236 and ME 236 (no, they're not the same route).

EDIT:

MA 101 and NH 101
US 7 and NY 7

Also, US 4 and NH 4.

US 95 on the California side of the Colorado River and AZ 95 on the eastern side in Arizona.  They actually meet in Quartzsite on the Arizona side.

WV 7 ends at a bridge which then crosses the Ohio and connects to OH 7 (this is not a situation of a state route keeping the same number in multiple states, OH 7 is a N-S road running in both directions from that point, WV 7 is a E-W road). 

[Mapmikey]

VA 193 and MD 193.  Both have an interchange with the DC Beltway...

VA 4 and NC 4

US 58 in Virginia and NC 58 are not all that far apart.

GA 4 and SC 4 are not very far from one another either.

[hotdogPi]

Do international borders count? US 1 and NB 1.

[hbelkins]

WV 7 ends at a bridge which then crosses the Ohio and connects to OH 7 (this is not a situation of a state route keeping the same number in multiple states, OH 7 is a N-S road running in both directions from that point, WV 7 is a E-W road).

Even though the bridge is technically WV 7, this is how it's signed from WV 2.

Plenty.  There's a thread somewhere that details many of them.

PA 73 and NJ 73 is one example.

There is a WV 7 posting on the road at the ramps to WV 2:  https://goo.gl/maps/YFPCfaZYtcB2

Not sure why WV assigns separate routes to some of these bridges if they don't sign them as such.  WV 807 isn't signed, though they did put a US 807 sign up for construction once - https://goo.gl/maps/kxzVf7Sntgq.  At least OH has 1 OH 807 shield on its side.  Not sure why the WV side isn't WV 16 - there are TO WV 16 shields at the WV 2 jct

Accounting.  All WV DOH work must be charged off to a particular route number.  So in the case of Ohio River bridges, all have a route number, either a "real" route the continues on the ground, or the bridge itself will be a 3dsr.  These are often unsigned, as knowing that number does not help a motorist.

Best example is WV 6, which links US 60 to Montgomery and WV 61. The route is not signed whatsoever; only "TO WV 61" and "TO US 60."

Also WV 106, which is the East End Bridge in Huntington.

I-35 and WIS 35 are separated by two miles in Duluth/Superior.

MN 48 and WIS 48 are a little further apart than most of these but close enough together to make me forget occasionally that they don't tie into each other.

[jp the roadgeek]

If we're talking different, non-continuous highways:

CT 2 and RI 2 (so much that Bing Maps used to connect the two via a US 1 concurrency in error)
RI 14 and MA 14 (didn't Roadgeekteen even propose connecting the two?)
ME 113 and NH 113 (about 5 mi. apart)
US 4 and NH 4 (about 5 mi. apart)
US 9 and VT 9 (connected by NY 7)
CT 12 and RI 12 (connected by CT/RI 14)
CT 124 and NY 124 (used to be connected)
US 1 and DE 1 (about 13 mi. apart)
PA 100 and DE 100 (used to be connected)
DE 7 and MD 7 (connected by US 40)
VT 103 and NH 103 (about 12 mi apart as the crow flies)
VT 10 and NH 10 (about 18 mi. as the crow flies)
NY 73 and VT 73 (about 23 mi. as the crow flies)
NY 208 and NJ 208 (about 22 mi as the crow flies)
PA 3 and DE 3 (about 10 mi as the crow flies)
DE 299 and MD 299 (about 4 mi. used to be connected, now connected by US 301)
US 9 and DE 9 (52 km (33 mi), connected by DE 1
MD 24 and PA 24 (about 8 mi.; connected by MD 136 and MD 23)
MD 28 and VA 28 (8 mi. across the Potomac; close until VA 28 is replaced by I-366 )

My statement was poorly worded.  I meant why a distinct separate number.  Two of the Ohio Bridges are WV 2 SPUR (one of which is OH 872 on the other side - why isn't this bridge designated WV 872 then?) and another is WV 62 SPUR.  OTOH, the Old US 21 bridge is an unsigned extension of WV 31 as well as the bridge with a poorly signed WV 7 extension.  They also have an unsigned extension of WV 27 to the Ohio River ferry.

WV 6 baffles me.  This designation goes back to at least 1970 and probably to the bridge's construction in 1956.  Other Kanawha River bridges are WV 61N and WV 25 SPUR.

I guess there is no rhyme or reason (or possibly each WVDOT district does it their own way)...

MO 51 and US 51 in Illinois.

MA 101 and NH 101

ME 101 in Kittery is also not far north.

IN 114 and IL 114 are within 20 miles of each other at their nearest point.
