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

[Beeper1]

The following-listed control destinations I've seen on either pull-through signs or exit signs for the below-listed Interstates.  Some of the road listings are not fully complete; feel free to add any control destinations I missed or not included.

EDIT: Not exactly retracting the above, but "redriving" this route on Streetview (I drove through there about three years ago) reveals that there is an Exit 1 at 82nd Street just south of this interchange, which Streetview indicates is where "27" becomes "87". I detect a violation of exit numbering criteria, especially since Texas does use "Exit 0" where appropriate.

Not a violation - Exit 1 is an option. There's no rule that a state has to use Exit 0 on every highway just because it uses it once.

Understood, but the exit pictured is exit 1A. Going north, the next exits are 1B and 1C. Either use exit 0 at the route terminus just south, followed by 1A, B, etc. to the north, or if the exits within the first two miles of the route are exits 1x as is common practice, make the first exit at the terminus 1A and this one 1B.

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).

No doubt that it is a control city on the Borman, but I think most of the signs have both Detroit and Toledo to account for the two routes. Some signs show Detroit only so that would be technically true. By the same logic, I-465 would then have Cincinnati and Peoria as control cities as would where I-65 and I-70 overlap.

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.

Those are the main ones, but there are some technical additions:

• I-65: Nashville (sign at exit 0 southbound), Toll Rd.
• I-69: Petersburg (as it is signed today)
• I-74: Crawfordsville (at Ronald Reagan Pkwy. interchange, but I think that is a fluke)
• I-80: Des Moines (on Toll Rd.)
• I-90: Chicago Skyway (at western end of Toll Rd.)
• I-265: New Albany, and Clark Maritime Ctr (not that either it or SR 265 actually make it there)
• I-275: Ohio and Kentucky
• I-865: Chicago and I-465

Most likely, I-69 will have "Memphis" from Evansville south as Indiana favors large control cities. I doubt that Bloomington would be a permanent control city.

On I-80/94 (Borman Expy stretch), Toledo does not get mentioned at all. Only Detroit. Even at the Toll Road interchange, there is no control city until you are on the ramp and the ramp says Ohio.
.
Also Des Moines is only mentioned on the Toll Road to 80/94. Once on 80/94, all the BGS have the WB control city as Chicago. The next mention of Des Moines (or Iowa for that matter) is in Illinois.

How come LA broke the rule of their own for signing local cities as control points like PA does on their interstates in Shreveport?  Dallas is used as control city for I-20 WB instead of one of the intermediate points like Monroe is used going east from there.  Bay St. Louis is used on I-10 from all interchanges in Slidell, LA including I-12 and I-59, etc.  Then Opelousas is used on I-49 from Lafayette northward instead of Alexandria which gives many of us indigestion cause the way the cookie crumbles at that location.

Louisiana did not follow suit here and acted like most states do in one instance.

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.

.
Also Des Moines is only mentioned on the Toll Road to 80/94. Once on 80/94, all the BGS have the WB control city as Chicago. The next mention of Des Moines (or Iowa for that matter) is in Illinois.

Well, I-80/I-94 in Indiana and the Borman Expy. are one and the same, but Toledo is certainly posted. I don't live there to know all signs, but these two pictures show Toledo is indeed posted on/for the Borman:




As for Des Moines, I agree and that is what I wrote.

I-84: Portland Airport, Hood River, The Dalles, Portland, Pendleton, Baker City, Ontario, Boise (only at the very edge of the state line)

There's one other one just east of Huntington, but that's it.

I'm not sure I understand your question. Are you saying Louisiana breaks the "rule" of posting local cities by putting places like Dallas and Monroe, or that it breaks the "rule" the opposite way by posting Opelousas or Bay St. Louis rather than larger cities? Louisiana's 3di's pretty much have the same control city as their parent. Or at least the 3di loops do:

220 - Dallas or Monroe, same as I-20
210 - Beaumont or Lafayette, same as 1-10
610 - Baton Rouge or Slidell, same as I-10

I don't think Monroe is an intermediate point. It is a city large enough to be a control city. I don't think there's an intermediate city or another city mentioned before Dallas going westbound because there really isn't a city large enough between the 2. (Longview is smaller but really only has 3-4 exits; Tyler is too far south of I-20)

As for Opelousas and Bay St. Louis, I really consider these to be leftovers that never got replaced once interstates were completed. Bay St. Louis was a control city because I-10 stopped at Mississippi's exit 2 (MS 607) defaulting travelers southward to US 90. Opelousas has gotta be from 49's early days when it was only 20 miles long from Lafayette to Opelousas. Although, there is one sign in Downtown Alexandria on I-49 Southbound at the Pineville Expwy (US 167/LA 28) exit that says Lafayette rather than Opelousas. That is also the newest section of completed 49 so far.

I stand corrected. The last time i was on the Borman about a year and a half ago, those signs were not up.

[Rover_0]

Here's what I got for Utah. Out-of-state control points are in parentheses, and (generally) listed in terms of use:

I-15: Salt Lake, (Las Vegas), Cedar City*, St. George*, Ogden, Brigham City**, Tremonton, (Pocatello)

I-80: Salt Lake, Wendover, (Reno), (Cheyenne), (Evanston)

I-70: Richfield, Green River, (Denver), (Grand Junction), Salina^, (Las Vegas)^^

I-84: Ogden, Brigham City**, (Boise), Morgan, (Cheyenne), (Evanston)

Not sure of any on I-215...

*Sometimes interchangeable, but Cedar City seems much more commonly used because of its more "central" location in S. Utah and was, until the late 1970s/early 1980s, larger than St. George.

**Used for both I-15 & I-84 because of their concurrency.

^More likely used for NB US-89 drivers, as the I-70/US-89 concurrency has its northern end at Salina.

^^Believe it or not, signs for WB I-70 (once west of Richfield) use Las Vegas as a control point.

Actually, the first.  It seems that Dallas is the only place in Louisiana that is not the next sequential city for the way of travel on its interstate system.  Only on I-10 between Baton Rouge and New Orleans is the next large city used because there are no smaller cities like Slidell, or Hammond in between the two.  I just thought that was odd, that's all.

[Mark68]

This makes sense, as almost all non-local traffic on I-70 west of Richfield will transition to I-15 south toward Vegas. I know it's the quickest route from Denver.

I always found Opelousas to be a strange chocie of control city.  At least other small control cities are highway junctions or something, like Hammond (Ih 12 and IH 55), Slidell (IH 10, IH 12, and IH59.)Monroe and Alexandria are fairly large enough cities, but Opelousas? 
The reason for Opelousas instead of Alexandria is a relic of the days when I 49 did not go to Alexandria.  With the improvements to it though, Alexandria should replace opelousas.

How come LA broke the rule of their own for signing local cities as control points like PA does on their interstates in Shreveport?  Dallas is used as control city for I-20 WB instead of one of the intermediate points like Monroe is used going east from there.  Bay St. Louis is used on I-10 from all interchanges in Slidell, LA including I-12 and I-59, etc.  Then Opelousas is used on I-49 from Lafayette northward instead of Alexandria which gives many of us indigestion cause the way the cookie crumbles at that location.

Louisiana did not follow suit here and acted like most states do in one instance.

I always found Opelousas to be a strange chocie of control city.  At least other small control cities are highway junctions or something, like Hammond (Ih 12 and IH 55), Slidell (IH 10, IH 12, and IH59.)Monroe and Alexandria are fairly large enough cities, but Opelousas? 
The reason for Opelousas instead of Alexandria is a relic of the days when I 49 did not go to Alexandria.  With the improvements to it though, Alexandria should replace opelousas. 

Pennsylvania has the same issue with Milford as a control city for I-84 EB as Milford is not even a major highway junction with another interstate.  It is a small borough and one traffic light in the entire corporation.  Middletown, NY or Newburgh, NY would make better choices cause both of those have other interstate junctions (well only one as NY 17 is not yet I-86) or even Hartford, CT as most travelers on I-84 are en route to the New England state.  Heck even Port Jervis would be fine as it is at the NY-PA State Border.

LA and PA both use sequential cities as control points instead of the next large cities unless it is the very next one.  The PA Turnpike does use Philadelphia over Harrisburg in some places in Western, PA where the State Capital is closest and a large enough metropolis.  Also, state names are used ie Ohio and New Jersey instead of the cities that are in those states.

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.

As mentioned by someone else earlier, no signage for Pascagoula in MS. To be honest, Pascagoula may not be a good control city since you actually have to travel through Moss Point if exiting from I-10. At least I-10 touches Biloxi and Gulfport and are significantly larger in both population and socially than Pascagoula.

Sorry, but Opelousas is more than legit as an I-49 control city for the following reasons:

It is the parish seat for St. Landry Parish.
It is the largest city between Lafayette and Alexandria.
It serves as a transition point for traffic wanting to use US 190 to/from Baton Rouge without crossing the Atchafalaya Basin.

Also, neither I-12 nor I-55 travel directly through Hammond to begin with, but due to its importance as a junction between I-12 and I-55, I would have no problem with Hammond as a secondary control city.

And..I'd say that even if I didn't live in Opelousas, too.
