Interstate in One State, but Both Directions Have Control Cities in Other States

[roadman65]

Does NH use cities outside itself on I-95 being only 17 miles within itself?

I know Boston is used SB, but what does NH use NB?

[StogieGuy7]

Doesn't I-294 use Wisconsin and Indiana for its control cities?

And I-90 and 94. 94 has both Wisconsin and Milwaukee IIRC.

On 94, the control city on the Edens (IDOT) is Milwaukee.  But once I-94 merges with the tollway, the control 'city' is Wisconsin heading northbound.  It's ISTHA that often uses whole states as controls, not IDOT.

I-55 has the states at I-90/94.

I-90 at Albert Lea - La Crosse & Sioux Falls.

You're right.  And I would say that a lot of the directional signage at junctions with tollways do the same. Perhaps they're trying to align with ISTHA? Because you don't see this downstate where interstates meet.

When I-26 is done in North Carolina, I suspect it will have Spartanburg and Johnson City.

I doubt it.  North Carolina is one of those states that prefers to post Control Cities within its own state until there are no other options.  I-95 in North Carolina should be posted with Richmond and Savannah throughout the state (another state skipper).

What would they use? Weaverville? Marshall? Mars Hill?

Also, I wonder if I-240 will be truncated to I-26 or if it will continue to be signed around to I-40. If I-240 stays on, I can see "Asheville DOWNTOWN" being used.

I-15 Las Vegas, Northbound lanes say Salt Lake City and SouthBound lanes say Los Angeles.

Lord only knows.  All of those are less populous than either Elkin or Jonesville, but you get my drift here.

[US 89]

I-80 in Salt Lake City (UT) uses Reno (NV) and Cheyenne (WY).

Interestingly enough, once you get out of the city, I-80 switches to local control cities (more applicable for rural areas) and as a result the westbound control becomes Wendover.

[ethanhopkin14]

I-65 in Nashville: Louisville and Huntsville.

I-81 in Hagerstown: Roanoke and Harrisburg.

When I-26 is done in North Carolina, I suspect it will have Spartanburg and Johnson City.

To that same vein, when I-69 is complete, I am sure in Arkansas it will have control cites of Shreveport and Memphis. 

[webny99]

Here's one that hasn't been mentioned yet: I-90 in Erie, PA uses Buffalo, NY and Cleveland, OH. Both cities are in use at Exit 22 (I-79 NB/SB), Exit 24 (US 19), Exit 27 (PA 97), and Exit 29 (PA 8).

All other exits use Erie itself in either one direction or the other. Personally, I'd like to see Buffalo instead of Erie at Exit 18 (PA 832), and Cleveland instead of Erie at Exit 32 (PA 430), bringing the total number of qualifying exits up to six, but that's a minor quibble.

I-70 in Hagerstown, MD uses Roanoke and Harrisburg for I-81.  The funny thing is the former is two states away.

Looking over this thread, it's amazing how many times this example came up.  It's a good one, though - not only are those the control cities used on I-70, as far as I can tell, they're used on every exit in the state.  I-81 has no Maryland control cities at all, at least in Maryland.  Hagerstown is used - but only in Pennsylvania and West Virginia.

How many places are there where a state skips over itself, despite the surrounding states not doing so?  Usually it's the reverse.

I-95 in Providence uses Boston (MA) and New York (even skips CT when using NY)
I-84 in Newburgh uses Danbury and Scranton

Not an interstate, but US 6 in Providence uses Cape Cod (multiplexed with I-195) and Hartford (CT)

[amroad17]

I-24 around Paducah, KY uses St. Louis (west) and Nashville (east).
I-295 around Richmond, VA uses Washington, DC (north) and Rocky Mt, NC (south).
I-80/90 (Indiana Toll Road) uses Toledo (east) and Chicago (west) at I-69 in Fremont, IN.
I-10 uses Florida (east) and Mississippi (west) at the I-65 terminus in Mobile, AL.
I-10 in Mississippi uses Mobile (east) and New Orleans (west) at most interchanges along the route.

I am sure that whenever I-26 is complete between Asheville and Mars Hill that it will be signed for Johnson City and Spartanburg at the new I-26/I-240 interchange.

Does NH use cities outside itself on I-95 being only 17 miles within itself?

I know Boston is used SB, but what does NH use NB?

Maine, or even more specifically "All Maine Points".  Really should use Portland.

[vdeane]

I-95's control cities in NH are wild.  "Maine Points", "All Maine Points", "To All Maine Points", and then simply "Maine".

[kphoger]

What's up with Points anyway?  How is that in any way more clear than just Maine?

Like, why would Chicago choose to sign Iowa Points on its signs?  How would that not actually less intelligible than just Iowa?

Do people in New Hampshire commonly talk about taking a weekend trip up (down?) to "the Maine points"?  Or, when they come back, do their friends ask them "What points did you go to?"

[SkyPesos]

I wouldn't mind seeing "Ohio Points" signed on I-90 WB between the OH-PA border and Erie. At least the highway takes you close enough to Cedar Point

[PHLBOS]

MA: I-95 uses Portsmouth, NH & Providence, RI between S. Lynnfield (Walnut St.) & Canton (I-93) at several locations along where it's concurrent w/128.

[hbelkins]

I-275 in Indiana: Ohio and Kentucky.

And I don't know how I overlooked this one. I-77 in Virginia: Bluefield (or Charleston) northbound and Charlotte southbound.

[amroad17]

its been a long time since i've been there...

... but i want to say the short stretch of i-70 in wv is posted columbus one way, and [some city], pa the other..

Washington, PA.  Same with I-470.

[interstate73]

From I-287 in New Jersey, the control cities are New York City, NY for I-80 East, and Del Water Gap, PA for I-80 West.

[Dirt Roads]

From I-287 in New Jersey, the control cities are New York City, NY for I-80 East, and Del Water Gap, PA for I-80 West.

You could assume that the control destination is the tiny borough in Pennsylvania, but I think that it is more commonly assumed as the geographic feature along the border of New Jersey and Pennsylvania (or even the National Recreation Area). 

[Roadgeekteen]

I-95's control cities in NH are wild.  "Maine Points", "All Maine Points", "To All Maine Points", and then simply "Maine".

All Maine points is the worst since there are parts of Maine where you should exit onto NH 16 to get to.

[Traffic]

Here's a few I recall from a trip this summer:

I-40 in Oklahoma City lists Amarillo (west) and Fort Smith (east)
I-35 in Oklahoma City (at I-40) lists Wichita (north) and Dallas (south)
I-40 in Amarillo has Oklahoma City (east) and Albuquerque (west)
I-55 in Memphis shows Jackson (south) and St. Louis (north)
