I live in Virginia and I'm not motivated enough to look up a full list, especially as to those in Southwest Virginia (where I seldom drive). Off the top of my head I can think of the following:

I-64: Norfolk (eastbound east of Richmond); Richmond (westbound and eastbound); don't recall otherwise but I seem to recall a sign on the I-81 concurrency mentioning Charleston (without a "WV" clarifier, which struck me as odd when I saw it).

I-66: Washington; Front Royal; Strasburg; some newer signs mention Manassas in conjunction with Front Royal.

I-77: I've only used it southbound (not counting I-81 concurrency) and I think I remember the signs listing Charlotte without an "NC" clarifier. I last used that road in December 2004 on a football trip to Charlotte.

I-81: Winchester; Roanoke; I believe south of Roanoke you see Bristol. Don't recall north of Winchester. I hate driving on I-81 in Virginia because so many car drivers can't seem to deal with all the trucks.

I-85: There aren't many overhead signs on I-85 itself. Distance signs generally list Durham, NC, on the bottom line (I seen to recall some include "NC" and some don't). The overhead signs on I-95 as you approach the I-85 exit have Blackstone and South Hill on one set of signs (both in Virginia) and Durham and Atlanta on the others (neither with state included).

I-95: Washington; Baltimore (without MD); Richmond; Rocky Mount NC; a couple of famous signs list Miami (once upon a time with FL, generally without)

I-195: I believe southbound this is signed "TO Powhite Parkway" without a control city. Don't know northbound. Usually I simply view this road from the Auto Train since it doesn't go anywhere I normally need to drive.

I-295: Charlottesville; Rocky Mount NC; might be others northbound but I do not recall as I've used it more often heading south.

I-395: Washington northbound, Richmond southbound

I-495: Tysons Corner; Richmond; Alexandria; Baltimore (Baltimore without a MD clarifier). Rockville (without MD) appears on some signs leading to the Beltway. Signs now reading "Tysons Corner" originally said "Frederick" (up in Maryland), but the business community in Tysons Corner objected.

I-581: Roanoke; Airport

I haven't been to the Tidewater area in a long time since my brother graduated from William & Mary, but I seem to recall I-564 being signed for "Naval Base." Don't recall the others. I-264 did not yet extend to Virginia Beach the last time I was down there, but I assume the signs most likely now say "Virginia Beach," "Norfolk," and "Portsmouth." I haven't been through Bristol since May 1997, but I assume I-381 southbound is signed "Bristol" and northbound is probably signed as "TO I-81."

I-77 Northbound from the I-81 concurrency lists Bluefield and Charleston, WV as primaries and possibly Beckley, WV as a secondary

I don't know if images of these were posted here before (they may have been).  On northbound I-95, these are the first two mentions of New York, both in Fairfax County, Va.

Between the Va. 123 (Gordon Boulevard) interchange in Prince William County and the U.S. 1 interchange in Fairfax County is this:



A few miles further north between Va. 602 (Lorton Road) and Va. 286 (Fairfax County Parkway) is this panel on the  right.  Prior to the completion of the Springfield Interchange reconstruction, the sign read "2 RIGHT LANES."

CONNECTICUT:

I-84 West in Danbury is signed as NY State.

Actually, a couple of the new signs at Exit 7 say Newburgh instead of NY State.  The ones at Exit 3 still say NY State.  Google Maps hasn't updated it yet, but I was out that way in early October.

[KEVIN_224]

You are correct! I'm not on that part of I-84 all too often. I do wish they had fixed that sign with all the others recently. Exit 3 for US Route 7 South is already a left exit there.

Golden Eagle:

No Pascagoula for I-10 in MS?

And I remember some exits for 220 in Jackson saying things like North Jackson, but that's more directional than a control city I guess.

That's in Alabama only.

In South Carolina:

I-20: Augusta, Columbia, Florence
I-26: Asheville, Spartanburg, Columbia, Charleston
I-77: Charlotte, Columbia, Charleston
I-85: Atlanta, Greenville, Spartanburg, Charlotte
I-95: Savannah, Florence, Fayetteville
I-126: Downtown Columbia, Elmwood Road, Spartanburg
I-185: Atlanta, Greenville Downtown, Columbia
I-385: Columbia, Greenville, Downtown
I-520: Augusta, Columbia
I-526: Savannah, Mount Pleasant
I-585: Spartanburg, Inman, Pine Street, Downtown

Now, I am adding a couple more - those in the Augusta area in Georgia.

I-20 Atlanta, Augusta, Columbia
I-520 Atlanta, Augusta, Columbia

BTW, the CSRA interstates in brownpelican's post are bolded.

Kentucky:

I-24: St. Louis/Paducah; Paducah/Nashville
I-64: Louisville/Lexington; Lexington/Ashland
I-65: Indianapolis/Louisville; Louisville/Nashville (sometimes Elizabethtown or Bowling Green will show up south of Louisville)
I-71: Louisville/Cincinnati
I-75: Lexington/Cincinnati; Lexington/Knoxville

I-264 at its western terminus at I-64 gets a control city of Shively.

I-64 also gets New Albany in downtown Louisville.

A couple additions for 3di's:

I-275 westbound in Northern Kentucky uses the Cincinnati Northern Kentucky International Airport as a control destination beginning from I-471.
On exit signs at that same interchange, I-471 northbound gets the control cities of Cincinnati and Newport, and I-275 east gets Columbus, Ohio.

In Ohio, I know of a few control cities used:

I-71 northbound gets Columbus, Cleveland and I think I have seen Mansfield also used just north of Columbus, though I might be wrong about that one.
For I-275 on the Ohio side of the river, Indianapolis and Columbus are used as you travel along I-75; Dayton (for I-75's northbound control city) and Kentucky are used where I-74 and I-275 are multiplexed (except at the I-74/275 interchange with Hamilton-Cleves Pike where Cincinnati is used eastbound); and on the eastern edge of the loop, Kentucky is used as you come down toward the river near the US 52 interchange.
I-471 gets Newport, Kentucky as a control.
I-270 uses Cleveland, Cincinnati, Dayton and Wheeling.
I-74 uses Indianapolis.
Oh, and a few miles outside of downtown Cincinnati, near the I-74 interchange, I-75 south uses downtown as a control point. Yet, on I-74 Eastbound at the same interchange, Lexington is used as the control city for I-75 Southbound. In the city of Cincinnati, Dayton is used for I-75 northbound.

[KEVIN_224]

I've seen Cleveland and Cincinnati while walking over I-71 in Columbus two years ago. This was looking down near Exit 109A for I-670, signed as "Airport/Dayton."

I-5 South Oregon from Portland - Salem, Eugene, Roseburg, Medford, Redding

I-5 North Washington from Portland - Seattle, Vancouver BC

I-84 East Oregon - The Dalles, Pendleton, Ontario

I've seen Yreka signed south of Ashland.  I think the first mention of Redding isn't until you hit Hornbrook, about 10 miles south of the OR/CA state line.
