What are all of the control cities on Interstates in your state?

[bassoon1986]

So this is partly because I want to know what the control cities are for interstate I'm not familiar with and partly because I know I'll see that some states flip-flop on control cities more than others. Let's keep it blue-shield interstates and not just freeways.

Louisiana:
I-10: Beaumont, Lake Charles, Lafayette, Baton Rouge, New Orleans, New Orleans Business District (at 610 split), Slidell, Bay St Louis
I-12: Baton Rouge, Hammond, Slidell
I-20: Dallas, Shreveport, Monroe, Vicksburg
I-49: (Texarkana), Shreveport, Alexandria, Opelousas, Lafayette, (Morgan City, Houma, New Orleans)
* these are assumptions for the future I-49 routes that are mostly in place already
I-55: Jackson, Hammond, New Orleans 
I-59: Hattiesburg, New Orleans

I-110:Natchez, Baton Rouge, Downtown, Metro Airport
I-210: Beaumont, Lafayette
I-220: Dallas, Monroe
I-310: Boutte, Houma, New Orleans, Donaldsonville (although Donaldsonville is more likely for LA 3127, and not on any 310 BGS)
I-510: Slidell, Chalmette, NASA,
I-610: Baton Rouge, Slidell


2 questions to my Louisiana peeps. Is it just me or did exits for I-55 north ever say Jackson, Miss?  And is Hammond a control city within LA for I-55 south, or just New Orleans?

[pianocello]

Iowa (eastern half):
I-80: Chicago, Iowa City, Davenport, Des Moines, more farther west
I-280: Des Moines, Moline, Rock Island
I-74: Davenport, Bettendorf (I think the only control cities are at the I-80 interchange)
I-380: Cedar Rapids, Waterloo, Iowa City

Illinois:
I-24: Paducah, I-57
I-39: Bloomington-Normal, Rockford
I-55: Chicago, St. Louis, Springfield, B-N
I-57: Effingham, Cairo, Memphis(?), Champaign, Chicago
I-74: Champaign, B-N, Peoria, Galesburg, Moline-Rock Island, Indianapolis
I-80: Joliet, Chicago, Moline-Rock Island
I-88: Sterling-Rock Falls, Chicago, Moline-Rock Island, (Dixon, Rochelle? not sure)
I-280: Chicago, Davenport
I-474: Morton, Galesburg, Moline-Rock Island, Indianapolis

In Chicagoland, Iowa, Indiana, and Wisconsin are used, as well as West Suburbs, NW Suburbs, SW Suburbs, etc.
Obviously this list is incomplete, but that's pretty much all I know of.

[tdindy88]

For Indiana:

I-64: St. Louis, Louisville
I-65: Louisville, Indianapolis, Chicago
I-69: Indianapolis, Fort Wayne, Lansing (future will have Evansville for SB and perhaps Bloomington or Indianapolis or Crane or something for northbound)
I-70: St. Louis, Indianapolis, Dayton (older signs have Columbus, OH)
I-74: Peoria, Indianapolis, Cincinnati
I-80: Chicago, Toledo/Ohio
I-90: Chicago, Toledo/Ohio
I-94: Chicago, Detroit
I-164: Evansville/Henderson, KY (at the northern interchange with 64/69)
I-469: Fort Wayne (mentioned at the southern interchange heading east onto I-469 at I-69)

*The last two examples are one-time mentions since Indiana doesn't normally do control cities on 3-dis.

[JustDrive]

Does I-5 have anything for Mexico listed since it crosses the border?

Aside from an "Int'l Border" mileage sign in Del Mar, there's nothing on I-5 that mentions Mexico.

[jcarte29]

For North Carolina, I feel confident about I-40, the others not sure, but here it goes

(even west-->east, odd north-->south)

I-40- Asheville, Hickory, Statesville, Winston-Salem, Greensboro, Burlington (co-signed with I-85), Durham (co-signed with I-85), Raleigh, Benson, Wilmington
I-77- Elkin, Statesville, Charlotte
I-85- Henderson, Durham (co-signed with I-40), Burlington (co-signed with I-40), Greensboro, High Point, Charlotte, Gastonia, Kings Mountain
I-95- Roanoke Rapids, Rocky Mount, Wilson, Benson, Fayetteville, Lumberton
I-26- Asheville

Future Interstates (partial and/or complete)
I-74- Winston-Salem, Asheboro (co-signed with I-73), Rockingham (co-signed with I-73), Laurinburg, Lumberton
I-73- Greensboro, Asheboro (co-signed with I-74), Rockingham (co-signed with I-74)

[hbelkins]

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.

[1995hoo]

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."

[NWI_Irish96]

For Indiana:

I-80: Chicago, Toledo/Ohio
I-94: Chicago, Detroit

Detroit is the Eastbound control city for the I-80/94 multiplex, so I guess technically Detroit is a control city for I-80 also (even though I-80 doesn't go there).

[Interstate Trav]

I-5 North also has Portland as a Northbound Control City

I-210 East also has Mtn Resorts and Redlands as Control Points
I-210 West lists San Fernando as a Control City west of Pasadena.  Sacramento only shows up on Mileage signs and other freeways transitioning to I-210.

[NWI_Irish96]

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.

St. Louis is a control city for westbound I-64 for a few miles.

[Urban Prairie Schooner]

2 questions to my Louisiana peeps. Is it just me or did exits for I-55 north ever say Jackson, Miss?  And is Hammond a control city within LA for I-55 south, or just New Orleans?

Hammond is a control city for I-55 NB only. SB from the state line to terminus has New Orleans as the control city.

[jcarte29]

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.

At least on the NC side, I believe Wytheville is the control city...and it might be Mount Airy on the VA side, but not sure.

[deathtopumpkins]

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-264 eastbound uses Portsmouth and Norfolk from I-664 to downtown Portsmouth, then starting at the Downtown Tunnel uses Virginia Beach, Va Beach, or Oceanfront (except for a number of signs between downtown Norfolk and I-64, which use TO 64 / 13 in place of a city.
I-264 westbound uses Norfolk and Richmond in Virginia Beach, then past I-64 uses Norfolk and Portsmouth until the Downtown Tunnel, where it changes to Bowers Hill, Chesapeake, and Suffolk.

I-464 northbound uses Norfolk and Portsmouth, and southbound uses Chesapeake.

I-564 westbound uses Naval Base, which also shows up as a control city on I-64 west between I-264 and I-564, and eastbound I do not know of a single sign listing a control city, as there is only one eastbound offramp before the I-64/I-564/US 460/VA 165 interchange complex.

I-664 northbound uses Newport News, Richmond, and Hampton.
I-664 southbound uses Suffolk and Chesapeake, though the exit signs from I-64 eastbound in Hampton also list Downtown Newport News, Portsmouth, and Nags Head.

Hampton Roads 3dis are remarkably devoid of pull-through signs, however, so many of these control cities only appear on one or two signs.

[Takumi]

I-295: Charlottesville; Rocky Mount NC

Also Washington northbound and Richmond Airport in both directions. There's also one New York City on I-95 northbound in southern Fairfax County.

[TheStranger]

I-5 North also has Portland as a Northbound Control City

Alright, will update my list above in a minute.

I-210 East also has Mtn Resorts and Redlands as Control Points

Is that true where it's still I-210 (at Route 57 in San Dimas)?  

I-210 West lists San Fernando as a Control City west of Pasadena.  Sacramento only shows up on Mileage signs and other freeways transitioning to I-210.

Gonna fix the list to reflect that.   Thanks.

[vdeane]

http://www.upstatenyroads.com/2di.shtml
The corresponding 3di page doesn't seem to have control cities on it.  Here's the ones I know of:
390: Corning, Rochester, Greece, Airport
490: Buffalo, Downtown Rochester, Victor
590: Downtown Rochester, Irondequoit (note: none of these appear on I-590 itself but do on I-390 northbound signage)
481: DeWitt, Oswego
890: Rotterdam, Schenectady
990: Lockport
190: Downtown Buffalo, Niagara Falls, Canada
290: Thruway, Niagara Falls
690: Baldwinsville, Downtown Syracuse

[1995hoo]

I-295: Charlottesville; Rocky Mount NC

Also Washington northbound and Richmond Airport in both directions. There's also one New York City on I-95 northbound in southern Fairfax County.

Yeah, I've seen that New York City sign. I didn't count it because it's a single sign, but I suppose under that logic the Miami signs maybe shouldn't count either.

[texaskdog]

I still wonder why if you're in Austin all the signs for I-35 North say "Waco" instead of Dallas or Fort Worth or DFW.  Who goes to Waco anyway?
