Interstates that closely approach a state without entering it

[KCRoadFan]

• I-44 at the Missouri/Oklahoma border, southwest of Joplin, just misses Kansas.
• I-80/I-90 in Indiana (the Indiana Toll Road), near the SR 9 exit, just misses Michigan.
• I-84 at the Pennsylvania/New York border, near Port Jervis, just misses New Jersey.

What are some other "near-miss" situations like the ones listed, in which an interstate makes a close approach to a nearby state without actually entering that state? (To be clear, this pertains to entirely artificial borders, across which the highway could potentially drift into the other state if it were shifted a little; interstates that run parallel to rivers or other natural features that happen to be state borders - such as I-29 near the Missouri River in Iowa or I-91 near the Connecticut River in Vermont - don't count.)

I-59 comes very close to Tennessee but ends at I-24 just before getting there.

Technically, I-41 and IL if you go by the signage.

I-68 comes within a couple miles of the PA border a few times. 

I-87 comes within a mile of NJ at Exit 15 (I-287/NY 17).

I-80 ends about 3 miles west of the GWB and the NY border (qualifies because it doesn't run parallel)

For now, I-11 ends at the AZ state line. Also, I-26 and the eastern I-74 end at the VA state line. 

I-65 gets within a few miles of FL near its southern terminus

I-287 at its east end is less than a mile from the CT border (the 1 mile advanced BGS on I-95 South is near the 0.4 MP in CT).  And I-495 in DE ends just feet south of the PA border.

I-80 comes very close to CO at the I-76 junction in NE but doesn't cross the state line (about 1.4 miles due south), whereas I-76 does enter CO near that state's NE corner.

I-495 (MA) almost hits both New Hampshire and Rhode Island.

[NWI_Irish96]

I-80/90 come very close to Michigan
I-80 ends fairly close to New York
I-71 and I-264 both end close to Indiana

I-68 comes within a couple miles of the PA border a few times. 

The curve just WB of the Sideling Hill rest area is about 1/5 of a mile south of the border.

I-80 ends fairly close to New York

i thought 80 ended 'at' new york -- in the middle of the gwb. didn't they extend the designation from.... whatever the place was where it used to split from the njtp. (paterson... something like that?)

It's not signed beyond the interchange with 95. Perhaps there's a hidden concurrency, someone local might know that.

I-64 near Huntsville is very close to Ohio, but doesn't get there.

I-68 ends in the narrowest part of Maryland, so it misses West Virginia AND Pennsylvania!

I-84 comes within FEET of crossing into New Jersey when crossing the Delaware river. It is incredibly close to the PA/NJ/NY tripoint.

Does I-8 coming within several hundred feet of Mexico count?

I-8 does not count as it is an interstate route for a federal nation not an interstate route in the sense of international states.

• I-44 at the Missouri/Oklahoma border, southwest of Joplin, just misses Kansas.

I-44 also comes pretty darn close to entering Illinois.

I-84 (Western) runs along the border of Oregon and Washington for over 100 miles, but never enters Washington.

According to FHWA's Interstate Route Log, there is no 80/95 concurrency.

I-35 in Duluth runs less than a mile from the Wisconsin border and has a "spur" into Wisconsin as well.

I-43 ends just over two miles from the Illinois border.

I always forget that US 66 clipped into Kansas, because I-44 misses it.

It does enter West Virginia elsewhere, though. Not sure whether that matters for purposes of this thread, but the spot you mention is one of the more interesting ones on the system even if it doesn't count.

I-57 comes really close to Kentucky.

I-172 comes pretty close to Missouri (and its parent route barely enters Missouri).

[hbelkins]

I'm seeing a lot of posts that don't count under the OP's criterion that roads that run near a river boundary don't count. Which eliminates the I-71 and I-264 Indiana mentions and the I-64 Ohio mention.

One that should be included here, but isn't for some unknown purpose, is I-26 in Tennessee. Both I-26 and its predecessor I-181 end(ed) at the US 11W interchange west of downtown Kingsport, yet the freeway continues on as US 23 to an interchange with TN 36 (old US 23) just south of the Tennessee/Virginia state line. There is no reason the interstate designation can't continue until the freeway's end. There is actually "To I-26" signage, which replaced "To I-181" signage, located in Virginia prior to the start of the ramp that carries US 23 southbound onto the freeway; said ramp beginning practically at the state line.

But I-381 in Virginia comes within about a mile of Tennessee. The interstate designation gives way to a surface route, sometimes posted as VA 381, north of the state line. You pass through a handful of traffic lights (including at the US 11/11E/11W/19/421 intersection) before reaching State Street and the state line.

Yes, I-68 ends at Morgantown, WV so that aspect is not correct; however, it comes very close to PA and is a very scenic and interesting alternative route that I very much enjoyed taking a few years back.

I-80 and Michigan. I-71 and Indiana. I-35 and Wisconsin.

There is an End I-80 sign, which is pretty memorable because it also says "Begin I-95 North," which is twelve hundred or so miles too late at this point: https://www.google.com/maps/@40.8658355,-74.0209437,3a,75y,71.11h,90t/data=!3m6!1e1!3m4!1sg5P9LqaGPaSDz8ex1Q4TNg!2e0!7i16384!8i8192

I-684 does enter Connecticut, but it has no connections to local roadways.  So in some way of looking at it does not really enter it.

[sprjus4]

I-16 ends about 2 miles just short of the South Carolina state line. US-17 continues the freeway north to the line, where it reduces to a 2 lane road.

I-540 ends just before the Oklahoma state line in Arkansas. It continues into Oklahoma as a four lane non limited access divided highway.

[TheGrassGuy]

I-680 is pretty close to PA, and I-376 is pretty close to OH.
